Layer Details
- Quilted cover. A traditional quilted cover treated with SmarTex and ProShield, which means it helps manage moisture and temperature while offering allergen relief. A sensible top layer if you're prone to sniffles.
- Geltex. A supremely breathable foam with an open-cell structure that reduces overheating. It also has excellent bounce back, so you won't feel stuck in one position.
- MemorySense ComfortCore. A core layer similar to memory foam that moulds around your body. This keeps joints, bones and muscles protected while you sleep.
- Dual firm foam layer. An additional stability layer. It adds to the firm, planted feel of the mattress as a whole.
- AlignSupport Coil Springs. Sealy's Posturepedic spring system, designed to align the spine by sensing and responding to your body weight. The springs are twice tempered, which means they hold their shape and resilience for longer.
- Base plank. A sturdy platform that supplies stable support for all the layers above. It helps avoid the mattress dipping in the middle over time.

- Leaves the rest of the room usable: At 90cm wide, it leaves space for a desk, wardrobe and toy storage in a child's room where the bed competes for every inch.
- Firm support that suits growing sleepers: The AlignSupport springs respond to body weight, which means a teenager gets proper spinal support rather than a saggy hand-me-down feel.
- Edge support matters more in a narrow bed: UniCased XT reinforcement keeps the sides usable, which counts on a 3ft width where you sleep closer to the edge by default.
- Cool for radiator-adjacent rooms: The Geltex layer's open-cell structure reduces overheating, useful in small bedrooms and loft rooms that hold their heat.
- A spare bed guests won't grumble about: The 27cm depth and hypoallergenic quilted cover give a guest room single a substantial, cared-for feel rather than an afterthought.
This size suits you if...
You're buying for a teenager or older child who needs firmer support as they grow, you're a single adult in a compact room or first flat where a 90cm width is the practical limit, or you're furnishing a spare room, perhaps one that doubles as an office, and want a single that feels like a proper bed rather than a stopgap.
Consider another size if...
You share the bed, or you're an adult sleeper who wants space to stretch out. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Is the Sealy Elevate Premier Gel UK single good for a child's room?
For older children and teenagers, yes: the firm AlignSupport springs give growing spines proper support, and the 90cm width leaves room for a desk and storage in a smaller bedroom. One caution: lighter children may find the firm surface a little unforgiving, as they won't sink into the comfort layers as much as a heavier sleeper would.
Will the UK single Sealy Elevate Premier Gel fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. The catch is depth: at 27cm, this is a substantial mattress, and many raised frames set a maximum mattress depth so the guard rail stays high enough. Check your frame's limit before buying; if it's under 27cm, this mattress isn't a safe fit.
What room size do I need for a UK single mattress like this?
We suggest at least 2.1m x 2.8m of floor space for a UK single, which is our guidance rather than Sealy's. That allows walking room alongside the bed. In a loft conversion, position the 90cm width along the slope and most rooms will take it, since the single's narrow footprint is the easiest of any size to place.
How much smaller is the UK single than the double in this mattress?
The UK single is 45cm narrower than the UK double, and the two are the same length. If you're an adult buying for yourself and the room can take it, that extra width is the difference between sleeping in one position and being able to spread out. For a child or a guest room, the UK single is usually plenty.
Is the Sealy Elevate Premier Gel single a good guest room mattress?
It's a strong fit for a spare room, particularly one doubling as an office where floor space is tight. Two UK singles plus a walkway can also work where one larger bed wouldn't. The firm feel won't suit every guest, but the breathable Geltex layer and reinforced edges make it a more comfortable single than most spare rooms offer.
