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.

- Sharing space that most bedrooms can take: At 135 x 190cm, or 4ft 6in x 6ft 3in, this size gives couples a proper shared bed in a footprint that fits typical UK rooms.
- Edge support that matters more at this width: With 67.5cm each for two people sharing, the UniCased XT reinforced edges let you use the full width without feeling you'll roll off.
- A soft feel that works for closer sleeping: Two people at this width sleep nearer each other, and the quilted pillow top cushions each sleeper's hips rather than forcing you to a firm middle ground.
- Cooling designed for two: Sharing a UK double means shared body heat, so the copper-infused graphite foam and mesh border are doing useful work here, moving air through a soft surface.
- Easy to dress and replace bedding: Standard double sheets and a 200 x 200cm duvet fit, and both are stocked everywhere, which keeps running costs down on a premium mattress.
This size suits you if...
You're a couple in a typical UK bedroom and want a soft, cushioned bed without giving the whole room over to it, you sleep on your side and share with a partner who does too, or you're kitting out a room where a bigger bed would leave no space for bedside tables on both sides.
Consider another size if...
You have a bedroom of at least 2.7m x 2.9m and either of you sleeps restlessly, because 67.5cm each is snug for two. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

Is the Sealy Elevate Ultra Supreme in a UK double big enough for a couple?
Yes, for most couples. The UK double is 135cm wide, which gives 67.5cm each for two people sharing. The reinforced UniCased XT edges help here, letting you both sleep close to the sides without the mattress giving way. Restless sleepers or taller partners may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Sealy Elevate Ultra Supreme UK double?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves enough clearance to walk round the bed and fit bedside tables on both sides. If your room comfortably exceeds 2.7m x 2.9m, it would also take the UK king, so it's worth measuring before you decide.
Will the UK double Sealy Elevate Ultra Supreme get up a narrow staircase?
Sealy doesn't publish delivery dimensions, but a 135cm wide hybrid at 34cm deep is a substantial thing to manoeuvre, and it won't fold like a boxed foam mattress. If you live in an older terrace with a turning staircase or a new build with a tight landing, measure the awkward points and check with the retailer before ordering.
Is a double or a king better for the Sealy Elevate Ultra Supreme?
It comes down to your room. The UK double suits bedrooms from 2.6m x 2.8m and is the sensible pick where a bigger bed would dominate. The UK king adds 15cm of width and 10cm of length, which restless or taller couples appreciate, but we'd only suggest it for rooms of at least 2.7m x 2.9m.
What bedding do I need for this mattress in a double?
Standard double sheets and a 200 x 200cm double duvet, both easy to find at every price. One caveat: at 34cm deep, this is a tall mattress, so choose fitted sheets labelled for deep or extra-deep mattresses. A regular fitted sheet may ping off the corners overnight, which gets old quickly.
