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.

Key benefits
- Room to sink in separately: With 75cm each for two people sharing, both of you can settle into the soft pillow top without ending up in each other's space.
- Less disturbance on different schedules: The AlignSupport coil unit responds gently to movement, and the extra width of a UK king means an early alarm on one side travels less far.
- Length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, a genuine relief for anyone approaching six foot on a soft mattress where feet tend to drift.
- Edges you can actually use: UniCased XT edge support keeps the sides of this 150cm width stable, so sitting on the edge or sleeping near it doesn't feel precarious.
- Airflow across a bigger surface: The copper-infused graphite foam and mesh border help a soft, deep mattress run cooler, useful when two people share one sleep surface every night.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a soft mattress you both settle into. It also suits couples on different schedules who want movement to travel less, and anyone approaching six foot who needs the 200cm length. If your room offers at least 2.7m x 2.9m, this size fits comfortably.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead, which is 15cm narrower and needs at least 2.6m x 2.8m of room.

FAQ's
Is the Sealy Elevate Ultra Supreme in a UK king big enough for a couple?
Yes, for most couples. The UK king measures 150 x 200cm, giving 75cm each for two people sharing. On a soft mattress like this one, that extra width matters more than usual, because you sink into the pillow top rather than lying on it, and cramped conditions become obvious quickly.
Should I choose the UK king or the UK super king in this mattress?
The UK king is 30cm narrower than the UK super king, and both are the same length. If one of you moves a lot at night, or a dog routinely claims part of the bed, the extra width may be worth it. We suggest at least 3m x 2.9m for the UK super king, so measure first.
What size room do I need for a UK king Sealy Elevate Ultra Supreme?
We suggest at least 2.7m x 2.9m for a UK king. That allows walking space around the bed and room to open drawers and wardrobes. New build master bedrooms can feel smaller than expected once furniture goes in, so measure the usable floor rather than the room's stated size.
Will standard king fitted sheets fit this mattress?
You'll need king sheets for the 150 x 200cm surface, but check the pocket depth carefully. This mattress is 34cm deep, which is more than many standard fitted sheets are cut for, so look for deep or extra deep versions. A 230 x 220cm king duvet is the usual pairing.
Is the UK king long enough for a tall sleeper?
At 200cm, the UK king is 10cm longer than the UK double, which helps anyone approaching six foot. The soft feel of this mattress means you settle down into it, so having spare length stops feet hanging over the edge. Sleepers well over six foot may still want to size up to the UK super king for width, though the length is the same.
