Layer Details
- Cover. A knit fabric woven with SmarTex and aloe vera, which draws moisture away from you overnight. That helps keep your sleep climate cool and fresh rather than clammy.
- Sealy INFUSE Copper. A copper-infused graphite foam layer that provides the comfortable top feel. The infusion also improves airflow, so heat is less likely to build up in the foam.
- ComfortCore. A targeted layer that concentrates pressure relief where you need it most, at the hips and lower back. This softens the firm feel just enough in the areas that carry your weight.
- AlignSupport coil spring unit. A patented two-stage spring system that senses your body shape and responds with deep, consistent support. The coils are twice-tempered, which means they're heat-treated twice to hold their resilience over the years.
- UniCased edge support. A reinforced perimeter that brings structure and stability to the mattress. It maximises the usable sleep surface and helps prevent that roll-off feeling near the edge.

- 90cm each for two sharers: Two people sharing get 90cm each, which means a partner who turns over frequently is simply further away and far easier to sleep through.
- Firm support across the full width: The AlignSupport coil unit keeps the same firm, consistent feel edge to edge, so neither sleeper drifts into a soft middle on a bed this wide.
- Edges you can actually use: UniCased edge support stiffens the perimeter, which means the outer inches of a 180cm mattress are proper sleeping space, useful when a child lands in the middle.
- Copper-infused foam over a big surface: A larger mattress holds more body heat with more people in it, and the copper-infused graphite foam and SmarTex cover help move that warmth and moisture away.
- Sized for larger rooms: We suggest a room of at least 3m x 2.9m, and in a big master or period bedroom this size fills the space where a UK king can look lost.
This size suits you if...
You share every night and want real distance from a partner who fidgets, or your mornings regularly include children or a dog and you'd like everyone to keep a fair share of the bed. It also suits you if you have a generous master bedroom, ideally around 3.5m x 3.2m, where a smaller mattress would leave the room feeling oddly empty.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m minimum, or it's just the two of you and space has never felt tight. We'd recommend the UK king instead, which is the same length, 30cm narrower, and needs at least 2.7m x 2.9m.

Is the Sealy Elevate Elite super king good for couples with a restless partner?
Yes, and the size does most of the work. With 90cm each, movement on one side is happening a long way from you, and the firm AlignSupport spring unit doesn't tip you towards a heavier partner. A firm hybrid transmits a little more motion than memory foam, but at this width you're unlikely to feel it.
What room size do I need for the Sealy Elevate Elite in a UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables on both sides and space to walk around. Before you order, check the door swing and any tight landing turns too, as a 180 x 200cm mattress is an awkward shape to carry upstairs.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All that extra space goes across the bed, which is exactly where you want it if children or pets join you at night. The firmness, 31cm depth and layer construction are identical in both sizes.
Can the super king cope with children climbing in at night?
Better than most sizes. At 180cm wide there's genuinely room for a small visitor without either adult ending up on the edge, and if you do get pushed outwards, the UniCased edge support keeps the perimeter stable rather than letting it sag under you. The firm feel also means a child in the middle doesn't create a dip everyone rolls into.
Does the Sealy Elevate Elite super king sleep warm with two people?
More bodies in one bed means more heat, but this size gives it somewhere to go. With 90cm each you're not pressed together, and the copper-infused graphite foam improves airflow while the SmarTex knit cover draws moisture away. It should run cooler than a standard foam-topped hybrid, although very hot sleepers may still want breathable bedding.
