Yes, split queen adjustable beds exist, but they are a niche size. A split queen is two narrow adjustable bases under two separate mattresses, each typically about 30 by 80 inches, that together fill a standard 60 by 80 inch queen footprint so each sleeper controls their own side. Few brands sell them, and the 30-inch mattresses and sheets are non-standard. SweetNight doesn't make one: its SenseSync base comes in Queen, which moves as one surface, and Split King.
That leaves three realistic paths: hunt down a split queen and vet the seller carefully, share a regular queen base, or make room for a split king. Here is how to pick.
What Is a Split Queen Adjustable Bed?
It is a queen-size bed cut lengthwise into two halves, each with its own adjustable base and its own mattress. According to Sleep Foundation's split queen guide, each half typically measures 30 inches wide by 80 inches long, though dimensions vary slightly by model. Two halves at 30 inches add up to the 60-inch width of a standard queen.
The width is the whole story. A Twin XL is 38 inches wide, and Sleep Foundation's twin vs Twin XL comparison notes the width is sometimes listed as 39. A split queen half is 8 inches narrower than that, which makes it an unusual mattress size. That is why Sleep Foundation warns regular twin sheets won't fit.
In fairness, 30 inches per person is roughly what each partner already gets on a shared queen. What changes is that you can no longer borrow space. On one mattress, a partner who curls up leaves room for the other to stretch into. On a split queen, your 30 inches is all there is, with an edge on each side.
Split queen vs split-head queen
Shoppers sometimes run into a second design with a similar name. Serta, as listed on its site in September 2026, offers its baselogic Gold base in a "Split Head Queen" version, described as letting you raise or lower each side of the bed independently, at a listed $1,699. Split-head designs generally divide only the upper part of the bed, so the head of each side moves on its own while the lower half is shared. They usually call for a mattress made for that design. Ask the brand exactly which sections are independent and which mattress it requires.
Split Queen vs Queen vs Split King at a Glance

Queen dimensions are from Sleep Foundation's queen size guide; split king figures are two standard Twin XL mattresses side by side. Our full adjustable bed size chart lists base dimensions too, which run slightly smaller than the mattresses.
Why Split Queen Adjustable Beds Are So Hard to Find
The base is not the difficult part. The mattress is. A split queen only works if someone sells a 30-inch-wide mattress that bends well on an adjustable base, and if you can still buy that mattress when the first one wears out. Twin XL mattresses are made by nearly every mattress company, so a split king owner can shop anywhere. A split queen owner usually depends on the company that sold the base.
Sheets follow the same logic. Twin XL fitted sheets are everywhere. Fitted sheets for a 30-inch mattress are a specialty item, and on an adjustable bed they need deep, fully elastic pockets because the surface stretches over the hinge every time the head rises. Our guide to sheets for adjustable beds explains why they pop off and what holds them.
Then there is demand. Couples who want independent sides and have the floor space almost always buy a split king, because it uses standard mattresses. That leaves split queen serving a narrower group: couples who want independent positions and whose bedroom tops out at queen width.
Who Sells Split Queen Adjustable Beds?
A handful of brands list a split queen, and Sleep Foundation maintains a roundup of them, so the size is real. It is not on most size menus, though. Of the three major base brands whose listings we checked in September 2026:
- Nectar offers Twin XL, Full, Queen, King and Split King across its adjustable bases, with no split queen.
- Tempur-Pedic's TEMPUR-Ergo bases come in Twin Long, Queen, King, California King, Split King and Split California King (plus Full on some models), with no split queen.
- Serta's baselogic Gold is the closest, with the split-head queen described above rather than two separate queen halves.
Before you buy a split queen from anyone, get clear answers to these questions:
- What is the exact width and length of each half? It varies by model.
- Do you sell mattresses in that exact size, and what are they made of? Foam that flexes with the hinge matters more on a narrow mattress.
- Will you still sell replacement mattresses in five or ten years?
- Do you sell fitted sheets and mattress protectors for that size, and how deep are the pockets?
- What is the weight rating per side, and does it include the mattress?
- Can the two halves be paired to move together from one remote?
- Can the base be returned? Some brands don't allow it. Tempur-Pedic, for example, states its power bases cannot be returned.
- How is the warranty structured year by year, beyond the headline number?
If a seller can't answer the mattress and sheet questions, treat that as your answer.
Who Makes Split Queen Adjustable Beds?
The name on the box is not always the name in the manual. Serta's baselogic owner's manuals, for example, come from Ergomotion Inc., and the Silver model also has a manual from Nisco. Retail brands often work with specialist base manufacturers. That matters for split queen buyers because, years later, warranty service and replacement parts come from whoever stands behind the product. Ask the seller who handles warranty claims and where replacement remotes and motors come from. A split queen from a brand that also makes its own matching mattresses is a safer long-term bet than a base-only listing.
Should You Get a Split King Instead?
If the room allows it, usually yes. A split king is 76 inches wide, 16 inches more than a queen. In return, each sleeper gets 38 inches instead of about 30, and every mattress, sheet and protector is a standard Twin XL you can buy anywhere.
The question is floor space. Sleep Foundation suggests leaving at least 24 inches on the foot and either side of a bed. With the head against a wall:
| Bed | Width with 24" each side | Length with 24" at the foot |
|---|---|---|
| Queen or split queen | 108" (9 ft) | 104" (8 ft 8 in) |
| Split king | 124" (10 ft 4 in) | 104" (8 ft 8 in) |
The 24 inches is a comfort guideline to avoid a cramped room, not a building code. If one side of the bed sits against a wall nobody walks along, some couples accept less clearance there. Tape both footprints on the floor, then open every door and drawer in the room before you decide.
A split king is what SweetNight offers for couples who want independent sides. The SenseSync Split King is two Twin XL bases, each rated for 400 pounds including the mattress, with remotes that work each side separately or pair so one remote moves both. (Disclosure: SweetNight makes the SenseSync adjustable bed base.) Each side needs a Twin XL all-foam memory foam mattress 12 or 14 inches thick. SweetNight doesn't sell a Twin XL mattress, so any all-foam Twin XL memory foam mattress of that thickness works, ideally two of the same height. Our split king adjustable bed guide covers the center gap, sheets and pairing in detail.
Sharing a Queen Adjustable Base: How to Make It Work
If a split king won't fit and a split queen feels like too much of a gamble, a regular queen base is the practical option. Both sleepers move together, and the head and foot still adjust separately from each other. The SenseSync Queen base measures 79.7 by 59.8 inches and is rated for 750 pounds, a figure that includes the mattress and both sleepers with weight spread evenly.
Couples who share a base well usually settle on a routine rather than a single perfect angle:
- Sit up together before sleep. Read or watch TV at a steeper angle, then press Flat at lights-out.
- Find a mild sleeping angle you both tolerate. The SenseSync Anti-Snore preset lifts the head about 15 degrees, a gentle angle that is a sensible place to start. For side sleepers, SweetNight's product team suggests starting around 5 to 8 degrees at the head and 5 to 12 at the foot.
- Save the compromise. The M1 and M2 memory buttons hold two positions, so one can be your shared sleep setting and the other your shared evening setting.
The mattress matters more on a shared base, because every turn a partner makes travels across one surface. All-foam generally keeps motion from spreading well, and it is also what SenseSync requires: all-foam memory foam, 12 or 14 inches. The CoolNest memory foam mattress comes in Queen at both thicknesses. For why a partner's movement wakes you and what reduces it, see why partner movement disrupts sleep.
Sharing stops working when one person needs a position every night that the other can't sleep in, such as a steep incline the other finds uncomfortable. That is the point where independent sides earn their cost, whether as a split king or, if the room truly can't fit one, a carefully vetted split queen.
Who a Split Queen Actually Suits
A split queen makes sense when three things are all true: the bedroom can hold a queen but not a king, both partners want different positions most nights, and the seller supplies matching mattresses and sheets in the exact size. If any one of those is missing, a shared queen base or a split king is the better buy.
Skip it if you like to sprawl, if either partner is broad-shouldered enough that 30 inches feels tight, or if you want to replace the mattresses later with whatever you find on sale. Before you look further, check whether the queen-vs-king question is really settled. Our queen vs king mattress comparison helps with that.
FAQ
Is there a split queen adjustable bed?
Yes, but it is a niche size. A split queen is two narrow adjustable bases, each carrying its own mattress, that together fill a standard 60 by 80 inch queen footprint. Far fewer brands offer it than offer split king, so check that the seller also supplies matching mattresses and sheets.
How wide is each side of a split queen?
Each half is typically 30 inches wide by 80 inches long, according to Sleep Foundation, though dimensions vary slightly by model. That is 8 inches narrower than a Twin XL. Because the width is not standardized, confirm the exact measurement with the brand before buying mattresses or sheets.
Do twin sheets fit a split queen adjustable bed?
No. Twin and Twin XL mattresses are about 38 inches wide, while each split queen mattress is typically 30 inches, so standard twin fitted sheets will be too loose. Buy fitted sheets made for that exact mattress width, ideally from the company that sells the split queen mattresses.
Does SweetNight make a split queen adjustable bed?
No. The SweetNight SenseSync adjustable bed base comes in Twin XL, Full, Queen and Split King. The Queen moves as one surface for both sleepers. For independent sides, the Split King pairs two Twin XL bases, each rated for 400 pounds, and needs about 16 inches more width than a queen.
Is a split king better than a split queen?
If your room can fit it, usually yes. A split king gives each sleeper 38 inches instead of about 30, and it uses standard Twin XL mattresses and sheets that are easy to find and replace. A split queen makes sense mainly when the room cannot take the extra 16 inches of width.
