A zero gravity bed is not a mattress you buy on its own — the tilt is what does the work. The head end lifts, the foot end lifts, and your body settles into a position where your spine is not fighting gravity all night. Two things matter more than anything else: how much the frame can actually incline, and how quietly and reliably it moves there. Get those right and you sleep better. Get them wrong and you own a very expensive flat bed.
I’m Mo Min — the founder and writer behind Non Toxic Blog. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every pick below is an adjustable base built to reach the zero gravity position, and I have matched each one to the buyer it genuinely fits. One important note before you read: this list uses flexible, human-like matching, so not every pick is the exact configuration you searched for — some are queen, some king, some twin XL, and some bundle a mattress with the base. Where a size or setup differs, I say so plainly so you are never caught out. That said, this is the most useful comparison of a 0 gravity mattress setup you will read today.
Our Picks at a Glance
How To Choose The Best 0 Gravity Mattress
The single biggest mistake first-time buyers make is shopping for a mattress and treating the base as an afterthought. It works the other way around. The base is the machine — the motors, the remote, the angle range, the weight limit. The mattress is what sits on top of it. Buy a great mattress for a weak frame and you get a comfortable flat bed. Buy the right frame and any medium-firm mattress on top of it will feel better at an angle than it ever did flat.
Start with the incline range, not the fabric
The head end is the part that matters most. Look at how far the head section actually rises, because that number decides whether you can sit up to read, watch TV, or reach the zero gravity position properly. The head angles on this list range from 57 degrees up to about 75 degrees. The foot end is the second half of the equation — a foot lift of 45 degrees is common, and a lower foot angle like 38 degrees is still enough to take pressure off your lower back but gives you a gentler slope. Zero gravity is the combination: head up, feet up, spine settled. If a base cannot do both independently, it is not really a zero gravity base.
Then think about who has to move it
These frames are heavy. Adjustable bases run well over 100 pounds, and some of the bundles ship in multiple boxes that arrive on different days. That weight is not a defect — it is steel and motors — but it changes the plan. Two people for setup is the norm, and a staircase makes it a three-person job. If you live alone, factor in help before the boxes land, and check whether the base folds for transport, because a foldable frame is far easier to get up a tight stairwell than a rigid one.
Match the mattress type to the moving frame
An adjustable base bends, so the mattress on it has to bend without cracking. Memory foam and gel foam handle that well. If you are buying a bundle, check how the mattress arrives — most of these ship compressed in a box and need time to expand, anywhere from 24 hours to 72 hours. Check the firmness too, because the same medium-firm foam reads as soft to one sleeper and too firm to another. A certified foam mattress (CertiPUR-US is the common one) and a fiberglass-free build are the two labels worth looking for if you care about what is in the foam.

In‑Depth Reviews
1. Irvine Home Collection King Adjustable Bed Base – Dual Massage – USB Ports – Zero Gravity – Underbed Light – Wireless Remote – Zero Clearance – Anti Snore – Memory Positions
Our pick — over 4.5★ from 300+ verified ratings; the strongest balance of quality and price.
The king base that lifts to 75 degrees and still shuts up about it.
If you want the most complete zero gravity base on this list, this is it. The head end rises to 75 degrees and the foot end to 45 degrees, which is the widest range here — good news if you read in bed, and better news if you use the foot lift to take load off your lower back. Alongside the dedicated Zero Gravity and Anti Snore presets, you get a One Touch Flat button and two memory slots so your own preferred angle is one press away. Dual massage motors target your upper body, lower body, or both, and the intensity is programmable.
What wins people over is how little drama the setup causes — screw in the legs, flip it over, plug it in, and you are done, with the maker claiming under five minutes and a second pair of hands recommended. Buyers of rival heavy bases in this category report the same: “Took a couple of guys about 15 minutes to set up.” This one folds for transport, which matters when the box is 80 inches long and the stairs are narrow. It also fits your existing mattress, frame, and headboard without a box spring, and the legs are height-adjustable.
The recurring gripe is weight — it is genuinely heavy, and paying delivery drivers to haul it upstairs is a real line item for some owners. Power outages stop it dead, so if your street loses power often, plan for that. The massage is vibration, not kneading, so its feel depends on how thick your mattress is, and a small number of units have had the USB charger or under-bed nightlight quit early. None of that changes the core picture: this is the best-balanced king base here, and it holds a 4.7-star score across 300+ ratings. It is also 124.1 pounds versus 121.3 pounds for the Beautyrest below — both are two-person jobs, so budget the help either way.
Where it earns its keep
- Widest incline range on the list at 75 degrees head and 45 degrees foot, with Zero Gravity, Anti Snore, One Touch Flat, and custom memory positions all on the remote.
- Assembly is genuinely quick — screw in the legs and plug in, with a foldable frame that is easier to get up stairs.
- Zero clearance design plus adjustable legs means it works on a platform frame or on its own.
What to plan around
- Heavy enough that one person cannot manage it — plan for two, or pay for carry-in.
- Won’t budge during a power outage, and the massage is vibration only, so its strength depends on your mattress.
Buy it if: you want a full-size king base with the broadest tilt range and every preset already built in.
Pass if: you need the base to still move during a power cut, or you want a kneading massage rather than vibration.
2. Beautyrest baselogic Silver Adjustable Base Bed Frame – Queen
The straightforward queen base that does zero gravity without the gadget pile.
This is the pick for anyone who wants the tilt and nothing else. The head and foot sections both adjust independently, and the remote carries a dedicated zero-gravity preset plus a one-touch flat reset — so getting into and out of the position takes one press, not a fumbling sequence. Body weight sits at 121.3 pounds, which is 2.8 pounds lighter than the Irvine king above; both are still heavy frames, so neither is a solo job. The 9-inch legs are solid and removable, which open up full zero clearance — pull them off and the base drops inside most platform bed frames.
The frame folds for transport and compact storage, so getting it through a doorway or into a spare room is manageable in a way a rigid base is not. Owners tend to describe this one as sturdy and quiet, with the anti-gravity setting standing out as the favorite part of daily use — for a partner with hip or back trouble, the difference shows up quickly. Setup reads as a short job too; buyers of rival heavy bases report the same 15-minute, two-person job.
Here is the honest catch: some owners find the included leg risers are not enough if you want your mattress sitting higher, and the massage option adds audible noise, though it runs on a timer. If you want a taller bed from the start, price extra risers into your plan. For a queen-size base with a real zero-gravity preset and full zero clearance, this remains the easiest way in.
The value read: four inches of leg height you don’t have to pay a premium for, plus a zero-gravity preset that actually gets used.
One thing to know: insufficient risers for a taller bed, so order more if you like sitting up high.
Right for you when: you already own a queen mattress and just want it to tilt.
Think twice when: you want the bed to sit tall straight from the start, or you need quiet massage.
3. Marsail Adjustable Bed Frame Queen with Mattress & Massage,Adjustable Base
Base and mattress in two boxes, zero gravity on one button.
Everything arrives together here — a queen adjustable base plus a 12-inch cooling gel memory foam mattress — so you are not hunting for a compatible mattress after the frame shows up. The base runs two motors and lifts the head from 0 to 60 degrees and the feet from 0 to 45 degrees independently, which covers reading, TV, and zero gravity without forcing you to choose one. Three-speed vibration massage runs through the frame in waves, and the whole thing assembles tool-free in about three minutes per the maker.
The thing that quietly matters most is what the frame is made of: the mattress is CertiPUR-US certified with a fiberglass-free design, and the frame is tested for 50,000+ cycles. If you have been burned by fiberglass shedding from a cheap bed-in-a-box before, that combination is the reassurance you actually wanted. The mattress itself is a three-layer build with a graphene-infused cover and open-cell foam, which is the part meant to keep you from waking up overheated.
The honest caveats are worth hearing. The mattress ships compressed and takes up to 72 hours to reach full shape, so the first couple of nights are not the final product. Firmness is the most debated point — some sleepers find it runs firm and add a topper. A few owners also note the mattress can slide slightly side to side on the base. Weighing in at 124.1 pounds for the set, this is not a solo setup.
What stands out: a fiberglass-free, CertiPUR-US certified mattress riding on a frame rated for 50,000+ cycles — that is the durability story, in plain terms.
The follow-up question: it may feel firmer than expected for the first few weeks, so give it time before you judge it.
Best pick for: buyers who want one order, one delivery window, and a bed that is ready to use together.
Consider skipping if: you want a plush mattress from the start — this one leans firm.
4. ESHINE King Adjustable Bed Frame Base – 3000 Premium Series
German-engineered motors and a decade of cover behind them.
The headline here is not the tilt — it is what is driving the tilt. Every motor in this king base, including the massage motors, is an OKIN system, which is the same family of motors used by brands that charge several times more. It is backed by a 10-year limited warranty, by far the longest cover in this group. Head and foot both incline on the dual-motor setup, the remote carries 19 buttons covering everything from a watching-TV position to anti-snore, and the legs adjust between 8 inches and 11.4 inches.
The full-body massage runs three intensity levels across three modes — wave, pulse, and full body vibration — with a 10-to-30-minute timer so it shuts itself off. Dual USB ports sit on the frame and under-bed night lights come as standard. The installation is genuinely the fastest here, with the maker quoting a 10-minute job and the listing also noting a 5-minute assembly; either way it is a screw-in-the-legs task that one capable person can mostly handle. For a king base with this motor pedigree, that is a lot of capability under one roof.
The trade-off to know about is quality control on the split-king configuration. Most arrive perfect, but a few owners found loose legs, bent end caps, or a disconnected wire on one of the two frames — fixable, but a hassle you should not have to sort out yourself. Weighing around 150 pounds, it needs two to three people and plenty of floor space to set up, and it fits a king frame snugly. If you get a good unit — and most buyers do — you own the most durable motor setup on this list.
Why buyers rate it
- OKIN motors throughout, including massage — the same engineering tier as premium-brand frames.
- 10-year limited warranty, the longest cover on this list, plus a 10-to-30 minute massage timer.
- 19-button remote with flashlight, dual USB ports, and under-bed night lights.
Worth knowing
- Split-king buyers occasionally receive one frame with loose legs or bent caps — inspect both on arrival.
- At roughly 150 pounds, setup needs two to three people and real floor space.
Choose this one if: the motor quality and a decade of cover matter more to you than the lowest sticker price in the group.
Look elsewhere if: you are setting up alone, or you would rather not deal with a possible split-king QC issue.
5. Nectar Premier Adjustable Base, Twin XL, Head & Foot, Massage
Built for two: buy two Twin XL bases and each side moves alone.
This one is designed around a specific couple. Each base is sold separately, and if you sleep with a partner you order two Twin XL units to build a split king, so each side adjusts independently. That means one of you can be flat while the other is tilted up — the whole reason split setups exist. The frame is steel and rated to hold up to 750 pounds, and the zero-clearance design means no mechanics stick out beyond the frame, so you can drop it onto a platform base or straight onto the floor.
Control is where this stands apart. You can run everything from the wireless remote or the Bluetooth app, save custom positions, and charge from four built-in USB ports. Massage comes with three intensity levels and a dedicated anti-snore setting alongside zero gravity. Setup is tool-free with batteries included, which is a small thing that saves a trip to the shop mid-assembly. Owners find it well-made and pleasant-looking — appearance is the single thing most praised — and it works flawlessly for most, holding a 4.4-star score across 350+ ratings.
The caveats are worth knowing before you order: the massage is vibration through the frame rather than deep tissue, so one buyer calls it more of a novelty, and some note the mattress can slide on the base, especially with a dog jumping on and off. Both are small compared to the upside. Ordering direct from Nectar is the smarter move if warranty confidence matters, since the warranty follows the product and covers a replacement if anything fails.
Pick it for: couples where one sleeper wants to sit up and the other wants to stay flat — the independent sides are the entire point.
One trade-off: the massage is frame vibration only, so do not expect deep-knead relief.
Reach for this if: you are building a split king for two people and want app control plus 750-pound capacity.
Look elsewhere if: you need a single queen base — this ships as Twin XL only.
6. Vipbear Full Size Adjustable Bed Frame with Massage,14 Inch Grey Gel Memory Foam Mattress
A full-size bed and mattress that arrives compressed and sets up fast.
If you sleep alone or want a guest-room adjustable bed, full size is the balance — smaller footprint, no wasted width — and this bundle pairs the base with a 14-inch grey gel memory foam mattress so the whole thing is one purchase. The head lifts from 0 to 65 degrees and the feet from 0 to 45 degrees independently, and the frame carries a dedicated 0 Gravity and Anti-Snore preset for one-press access to both. High-strength steel supports up to 750 pounds, so it handles heavier sleepers without flex.
Control options go beyond the remote here: there is a mobile app and voice control as well, which is rare at this price. A 3.5-inch thickened foam frame sits around the steel, and adjustable legs let you dial in the bed height. The mattress is medium-firm with a removable cover and a fiberglass-free cooling gel and tea foam build using CertiPUR-certified foams. Owners describe the motor as whisper-quiet and the mattress as comfortable — not too firm, not too soft — and there is a lifetime warranty attached, which is unusually generous for this category.
Two things to plan for. At 139 pounds the frame is heavy, and the manufacturer’s own guidance is that two people should move and assemble it. The mattress ships in a box and expands over 24 to 48 hours, so it will not be at full form on night one. And the foam sleeps slightly warm for some sleepers, which a cooling blanket solves cheaply. None of that undercuts the value — a full-size adjustable set with massage at this price is hard to match.
The standout spec: a 750-pound steel capacity on a full-size frame, so the base stays rigid no matter the load.
What to expect: the foam runs slightly warm, and the box is heavy enough to need a helper.
Pick this if: you want a full-size adjustable bed and mattress in one order with a lifetime warranty.
Skip if: you want a king, or you are sensitive to foam that sleeps a touch warm.
7. Pipishell Adjustable Bed Frame Queen with Massage and 12” Mattress Set
Four leg heights and a bed that looks good doing it.
Appearance is what sells this one — owners call it sleek, and for a bed frame that is genuinely hard to earn. Beneath the look it is a queen base with independently adjustable head and feet, lifting up to 65 degrees and 45 degrees, plus a zero gravity setting and a retainer bar that keeps the mattress from creeping. Dual motors drive both a head and foot massage, with four modes and three intensity levels, so you can target one area or run both.
The practical standout is the leg range. Interchangeable 2-inch, 3-inch, and 8-inch sections let you set the bed at 8, 10, 11, or 13 inches — four options in one frame — so you can either lower it for easier getting in and out or raise it for under-bed storage. A soft under-bed night light handles those middle-of-the-night trips, and the electric base supports up to 750 pounds. The bundle includes a 12-inch mattress with a graphene-enhanced cover meant to pull heat away, and the foam is CertiPUR-US certified.
Here is where it gets honest: a couple of owners find the mattress softer than described and note it slides on the base, wanting an extra side rail to hold it. The massage motors are on the smaller side and adjust slowly, with the vibration described as subtle and slightly noisy. It also ships as two boxes that may arrive separately, so do not panic if only one shows up first. If you care most about looks and height flexibility, this is your pick; if you need a firm mattress or powerful massage, go elsewhere.
Best for: buyers who want a low-entry bed, since 8-inch legs make it easier to swing your legs out and stand.
Not for: firm-mattress fans or anyone who needs a heavy-duty massage motor — those run slow and subtle here.
Choose it if: getting in and out easily matters, or you want a bed that looks sharp in the room.
skip it if: you need a firm mattress — this one reads soft to some sleepers.
8. Amada Queen Adjustable Bed Frame and 12 Inch Cooling Gel Memory Foam Mattress Set
The remote does the thinking so you don’t have to at 2 a.m.
This queen set leads on one-click convenience. The backlit remote carries one-touch Anti-Snore, Zero Gravity, and Flat presets plus two memory slots for your own favorite angles, so you rarely have to fiddle with individual buttons. Under-bed LED lights and the charging ports are controlled from the same remote. The head lifts to 65 degrees and the feet to 45 degrees, running on a 750-pound base with a retainer bar, and the mattress layers gel-infused memory foam over wave-cut foam with a graphene-infused cover meant to keep you cool.
The tool-free three-step assembly is the other selling point — no tools, and interchangeable 2-inch, 3-inch, and 8-inch legs give you four heights: 8, 10, 11, and 13 inches. The foam is CertiPUR-US certified and fiberglass-free. Owners call the mattress soft yet supportive and say it helps sleep quality, especially for side sleepers who hold the tall corners with deep-pocket sheets. It holds a 4.4-star score across 280+ ratings, and most buyers describe setup as a matter of minutes.
Two things to know: it is heavy and awkward to move alone, and it will feel different from a traditional mattress for a week or two while you adjust — the medium-firm foam settles in as it breaks in. The foam uses a cooling cover and gel layers, but if you sleep hot, do not expect it to feel cold. For a presets-first queen set with tool-free assembly, this is a clean fit.
The draw: one-touch Anti-Snore, Zero Gravity, and Flat buttons, plus two memory slots — the friendliest remote in the queen group.
The caveat: it is heavy to maneuver alone, and the new-foam feel takes a week or so to settle in.
Best for: buyers who want preset buttons and a tool-free setup with no wrench required.
Think twice if: you like a firm feel from the start — this one breaks in over time.
9. Irvine Home Collection Premium Full Adjustable Bed with 14 Inch Prime Gel Memory Foam Sleep System
The full set that feels like a hotel room moved in with you.
Everything about this one points upmarket. The head section inclines to about 75 degrees and the feet to about 45 degrees, with Zero Gravity and Anti-Snore presets plus programmable memory positions on the intuitive remote. Dual massage motors give you three intensity levels, and the frame carries USB and USB-C charging ports, under-bed LED lighting, a backlit remote, and a remote pouch. The zero-clearance design means you can set it on box springs or slats and skip the legs entirely, or swap in the adjustable legs up to a 12-inch height.
The mattress that comes with it is a 14-inch medium-firmness build — cooling gel-infused copper memory foam over a transitional support layer and a durable base foam. If you want the bed to feel like a considered purchase rather than a compromise, that three-layer stack is where the difference lives. The included extended premium warranty and a dedicated nationwide service contact for warranty claims and replacement parts round out the package. Owners praise the luxury-height feel and the attention to detail, and repeatedly call out the zero gravity setting as the noticeable difference.
The honest trade-off is weight. This is a heavy frame and most owners say a second person makes the setup go smoothly — one buyer even ended up with help bringing it inside after the delivery service called ahead. A handful found the manual diagram showed one wire where two needed connecting, so watch for that at assembly. Get past those two steps and what you have is the most feature-dense base here, holding a 4.4-star score across 440+ ratings.
The standout build: cooling gel-infused copper memory foam over two support layers, at a 14-inch medium-firmness profile.
What’s left unsaid: it is heavy and the manual has a wire-count quirk at setup, so read the diagram carefully.
The premium pick for: buyers who want a full-feature base and a quality mattress in one package with service included.
Worth a second look if: you are setting it up solo — plan for a helper.
10. Vipbear Split King Adjustable Bed Frame with Mattress, 12 Inch Gel Memory Foam
Two halves that move on their own, and a lock for little hands.
Split king is the configuration that lets two sleepers do entirely different things, and this bundle pairs a split king base with a 12-inch grey gel memory foam mattress in the same order. Head and foot sections lift independently, 0 to 65 degrees and 0 to 45 degrees respectively, and the frame carries 0 Gravity and Anti-Snore presets. High-strength stainless steel supports up to 750 pounds per side. The details that stand out are the ones built for a household with kids: a child lock on the remote so nobody rockets the bed up while you are resting, and mobile app control alongside the wireless remote.
The mattress is medium-firm with strong support, a removable cover, and a fiberglass-free cooling gel and tea foam build using CertiPUR-certified foams. Owners describe it as comfortable, easy to set up, and sturdy, with the medium-firm feel called out as hitting the mark — better than expected for the money. It also carries a lifetime warranty. If you want a split king that is honest about its foam and its steel, this delivers.
The caveat that shows up in owner feedback is not the bed itself — it is the delivery. Several buyers received the mattress before the frame, or had a box arrive damaged in transit, and the resolution took longer than anyone wanted. The customer service does respond and does make it right, including refunds for damaged parts. Order early and inspect the boxes, and you will be fine. It holds a 4.3-star score across a smaller but positive base of ratings.
Pick it for: the child lock — if you have kids or pets that like buttons, this is the only pick here with that safeguard.
Watch for: split shipments, so check the boxes on arrival and confirm both parts are intact.
Right for you when: you want split king independence with a mattress included and a remote lock for the household.
Look elsewhere when: you want a single-piece base — this is two independent halves by design.
11. Dyonery Split King Adjustable Bed Frame + 14 Inch Memory Foam Mattress
The split king people buy for a reason, not for a discount.
This is the premium end of the split king group, and the numbers back it up. The base lifts the head to 57 degrees and the feet to 38 degrees — a gentler slope than the 65-degree picks above, which some sleepers prefer because it feels less like sitting up and more like floating. The updated zero clearance mechanical design means you can run it without legs at all, so it drops neatly inside an existing headboard, footboard, and side rails. It holds up to 700 pounds. Tools-free assembly is the norm here, with most owners reporting a 10-to-15-minute job.
The mattress is where this one separates itself from the pack. It uses gel copper memory foam for temperature regulation, and it is certified by both CertiPUR-US and Oeko-Tex Standard 100 — the second certification is the strict one on harmful substances, and it is rare to see both on the same mattress. Both certifications mean the foam and fabrics are independently tested against mandatory and voluntary mattress safety standards. If you want the cleanest build you can get in this category, that certification pair is the strongest signal on the list.
Where it earns its place is versatility. Owners use it for couples who sleep differently, for recovery after surgery, for a husband with Parkinson’s who needs help getting out of bed, and even in an RV — a range that speaks to how reliably the frame moves. The recurring honest note is the mattresses cannot be returned once opened, so be sure about the size before you unwrap. The mattress runs firm-medium, and some owners add a topper. It carries a 4.5-star score across 600-plus ratings, the strongest confidence signal here.
What makes it premium
- Double-certified mattress: CertiPUR-US and Oeko-Tex Standard 100, a rare pairing at any price.
- 700-pound capacity with tools-free assembly and a gentle 57/38 degree tilt.
- Gel copper memory foam built for temperature regulation, not just pressure relief.
The honest limits
- The mattress cannot be returned once opened, so the size decision is final.
- The 57/38-degree tilt is gentler than the 65-degree-degree picks above — better for some, less for those who want a steep sit-up.
For the buyer who: wants a premium split king with the cleanest mattress certifications and a gentle zero-gravity slope.
Think twice if: you want a steep 65-degree recline, or you are unsure about the size — returns are not an option once the mattress is opened.
Understanding the Specs
Head and Foot Incline Angles
These two angles are the heart of any zero gravity setup. The head number tells you how far the top of the bed rises — the range across these picks runs from 57 degrees up to about 75 degrees. A steeper head angle lets you sit up properly to read or watch TV; a gentler one feels more like a floating recline. The foot number, usually 38 to 45 degrees, is what takes load off your lower back and legs. Zero gravity is simply both raised at once so your spine is supported and pressure is spread out. If a base only lifts one end, it cannot reach the position.
Weight Capacity and Frame Weight
Weight capacity is the load the frame can hold, motors and all — several picks here are rated for 750 pounds. It matters if two people share the bed or if you want to know the frame will not strain over years of use. Separately, the frame’s own weight is the number that affects your moving day. These bases run well over 100 pounds, and some bundles tip toward 140 pounds. Heavy is good for stability and quiet operation; it is bad for stairs and solo setup. Plan for two people on arrival, whatever the capacity figure says.
Zero Clearance and Leg Heights
Zero clearance means nothing mechanical extends below the frame deck, so you can set the base directly on a platform bed, on slats, or on the floor without legs. That is the pick for anyone who already owns a bed frame they love. The alternative is adjustable legs — a few bases here offer multiple height settings, letting you go low for easy standing or high for under-bed storage. If you want your current headboard and footboard to stay in use, check the zero clearance design first.
Mattress Type and Certifications
An adjustable base bends, so the mattress on it needs to flex without cracking — memory foam and gel foam are the right match. When a bundle includes a mattress, two things are worth checking. First, how it arrives: most ship compressed and need 24 to 72 hours to expand fully. Second, what is in the foam — CertiPUR-US and Oeko-Tex Standard 100 are the certification labels to look for, and a fiberglass-free build is worth seeking out if you care about what is inside. Firmness is personal, so treat any “medium-firm” label as a starting point and adjust with a topper if needed.

Final Thoughts: The Verdict
For most people, the winner is the Irvine Home Collection King Adjustable Bed Base — its 75-degree head and 45-degree foot range is the widest here, and it bundles zero gravity, anti-snore, memory positions, dual massage, USB ports, and under-bed lighting into one frame that folds for transport. If a full-size set with a lifetime warranty appeals more, the Vipbear Full Size Adjustable Bed Frame with Mattress pairs a 750-pound steel base with a 14-inch gel foam mattress in a single order. And for a couple who wants each side to move independently with the cleanest mattress certifications on the list, the Dyonery Split King Adjustable Bed Frame is the one to reach for, backed by CertiPUR-US and Oeko-Tex Standard 100 foam. Whichever you pick, plan for two people on delivery day — these frames are built heavy for a reason.
