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.

- Distance from a restless partner: With 90cm each for two people sharing, movement on one side has much further to travel before it reaches you.
- Softness that works better with space: A soft, sink-in surface is easier to enjoy when you're not clinging to your half, and this size gives both of you room to settle.
- Room for the whole household: Children who appear at 3am or a dog who considers the bed theirs can join without anyone ending up on an edge.
- Edges you can actually use: The UniCased XT reinforced border matters more at this width, letting you sleep right to the sides rather than losing usable space.
- Real presence in a large bedroom: In a big master or period room where a UK king can look undersized, the 180cm width fills the space properly.
This size suits you if...
You share every night and want the maximum standard UK size, your sleep gets broken by a partner who turns over a lot, or children and pets regularly join you and a UK king has started to feel crowded. It also suits a genuinely large bedroom: we suggest at least 3m x 2.9m for a super king, with around 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest for a super king, or you'd struggle to get a 34cm deep mattress up your stairs. The UK king is 30cm narrower, the same length, and needs only 2.7m x 2.9m: we'd recommend that instead.

Is the Sealy Elevate Ultra Supreme super king good for restless couples?
It's one of the better choices for this. With 90cm each for two people sharing, a fidgety partner is simply further away, and the AlignSupport spring unit responds gently rather than bouncing. Soft mattresses transfer a little more movement than firm ones, so at this size distance does most of the work.
What size room do I need for the Sealy Elevate Ultra Supreme super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right if you want bedside tables on both sides and space to walk around. Check door swing too: at 180 x 200cm this mattress takes up a lot of floor, and a door that opens into the room eats into your margin.
Will the Sealy Elevate Ultra Supreme in a super king get up my stairs?
This is the check that bites at this size. At 180 x 200cm and 34cm deep, it's a heavy, bulky item, and the pillow-top hybrid build doesn't fold the way a rolled foam mattress does. Measure your stairwell and any landing turns before ordering, and check the retailer's delivery access guidance.
What bedding fits the Sealy Elevate Ultra Supreme super king?
You'll need super king sheets, and a 260 x 220cm duvet suits the 180cm width. The catch is depth: at 34cm, standard fitted sheets may not stretch over the corners, so look for deep or extra-deep versions. Bedding costs more at this size, which is worth budgeting for alongside the mattress.
Is a super king worth it over a king for this mattress?
If children or pets share regularly, yes. The UK super king is 30cm wider than the UK king and the same length, and that extra width is the difference between everyone having space and someone hanging off the side. If it's just the two of you and you sleep calmly, the UK king may be plenty.
