Layer Details
- Pillow top. A quilted foam and eternity fibre pillow top, which means an extra layer of inviting softness the moment you lie down. This is where much of the plush feel comes from.
- Cover. A fabric cover woven with SmarTex and aloe vera, designed to keep the sleep surface clean, cool and fresh.
- Sealy INFUSE Copper. A copper-infused graphite foam layer for comfort with enhanced airflow, which should help offset the warmth soft mattresses can sometimes trap.
- MemorySense ComfortCore. A targeted layer that focuses pressure relief on the hips and lower back, the areas that tend to complain first on an unsupportive mattress.
- AlignSupport coil spring unit. Sealy's patented spring unit offers two stages of support, so it responds gently at first and then firms up as you settle in. The coils are twice-tempered for durability.
- UniCased XT edge support. Reinforced edges bring structure and stability, maximise the usable sleep area and help prevent roll off. Useful if you sit on the edge of the bed or share with a partner.
- Mesh mattress border. A breathable mesh border around the mattress for added ventilation.

- Full comfort spec, one-person footprint: Every layer of the model, from the quilted pillow top to the AlignSupport springs, appears in the UK single, so a solo sleeper gets nothing cut down.
- Soft feel suits lighter bodies: The soft, sink-in surface tends to work well for children and lighter teens, who often find firmer mattresses unyielding at this size.
- Edge support widens a narrow bed: UniCased XT reinforced edges matter more at 3ft wide, letting you sleep right to the border without the roll-off feeling.
- Cooling layers for small rooms: The copper-infused graphite foam and mesh border help airflow, useful in compact bedrooms and loft conversions that run warm in summer.
- Fits where doubles can't: At 90cm wide it leaves floor space for a desk, wardrobe or toy storage, and two singles plus a walkway can share one room.
This size suits you if...
You're a solo adult who wants a genuinely plush mattress without moving up to a double, you're buying a long-term bed for a teenager's compact room, or you're furnishing a guest room or a first flat where the frame is a single and you refuse to put a thin budget mattress on it. Side sleepers get the most from the soft feel.
Consider another size if...
You share the bed, or you're an adult who likes room to spread out. We'd recommend the UK double instead: it's 45cm wider than the UK single, the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

What size is the Sealy Elevate Ultra Supreme UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in, the standard UK one-person size. We suggest allowing at least 2.1m x 2.8m of floor space so you can walk around the bed and open drawers comfortably. Standard single sheets fit the width, though at 34cm deep you'll want deep-pocket fitted sheets.
Will the Sealy Elevate Ultra Supreme single fit a bunk or mid sleeper?
Probably not, and we'd urge caution. At 34cm deep, this mattress is far taller than most bunk and cabin frames allow, which means the guard rail may sit too low to be safe and the sleeper too close to the ceiling. For raised frames, a slimmer single is the sensible choice; keep this one for a standard bedstead.
Is a UK single Sealy Elevate Ultra Supreme good for a child?
For an older child or teenager, yes, with caveats. The soft surface suits lighter bodies and side sleepers well, and the 90 x 190cm footprint leaves room in a small bedroom for a desk and storage. It's a premium spend for a child's bed, though, so it makes most sense as a long-term purchase they'll grow into rather than out of.
How much bigger is a UK double than this single?
The UK double is 45cm wider than the UK single and exactly the same length, so you gain width for a second sleeper or extra sprawl without needing a longer room. We suggest at least 2.6m x 2.8m of floor space for the UK double, against 2.1m x 2.8m for the single.
