Layer Details
Cover
A dual-sided graphite cool cover: one side uses heat-removing graphene, the other a soft teddy bear fabric. Flip it seasonally, which means a cooler surface in summer and a warmer one in winter.
Comfort layer
StaycoolTM gel provides body-sensitive pressure relief while helping to keep you cool. In practice, it cushions your hips and shoulders without letting heat build up.
Support layer
A high-density support layer with polyester fillings sits beneath the gel. This adds structure, which means the comfort layer above has a stable base to work from.
Springs
Pocket springs form the base, with 2,000 in the king size. Each spring moves independently, which means better contouring and less motion transfer between partners.

Key benefits
- Room to spread out: You get 90cm each for two sharing, 15cm more each than the UK king, which means a partner's tossing and turning reaches your side far less often.
- Distance and independent springs together: The pocket springs move independently, and the extra width puts more mattress between you, which does more than any comfort layer to quieten a fidgety partner.
- A share for everyone at 3am: When a small child climbs in, or a large dog sleeps at your feet every night, both adults still keep a usable strip of mattress rather than clinging to the edge.
- Extra width, same length: At 200cm long, the UK super king matches the UK king for length, so you're buying elbow room here rather than legroom.
- One seasonal side for both of you: Whichever face of the dual-sided cover is uppermost, graphite cool or teddy fabric, you both sleep on it, so couples who disagree on temperature may prefer separate duvets.
This size suits you if...
You share with a partner who tosses and turns, or you regularly wake to find a child or dog between you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room is smaller than 3m x 2.9m, or turning a 180cm-wide mattress regularly sounds like too much. We'd recommend the UK king instead, where we suggest at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee SmartTemp Seasons super king hard to turn?
It takes some effort. This mattress needs regular turning so you can switch between the cool and warm sides, and at 180cm wide and 28cm deep, the UK super king is realistically a job for two people. Sleepeezee doesn't publish a weight for this size, so plan on having a second pair of hands.
How much more space does the SmartTemp Seasons super king give than the king?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. When two of you share, that works out at 90cm each on the UK super king against 75cm each on the UK king, so 15cm more each.
Is a Sleepeezee SmartTemp Seasons super king big enough for a couple and a child?
For the occasional night, yes. With 180cm of width, a child who wanders in at night can settle in the middle while both adults keep a reasonable share. If a child sleeps with you every night, you'll still notice the squeeze, although far less than on a UK king or UK double.
Can two people with different temperature needs share the SmartTemp Seasons super king?
Partly. The whole cover flips together, so on a UK super king you both sleep on the graphite cool side or you both sleep on the teddy fabric side. If one of you runs hot and the other runs cold, separate duvets on top usually bridge the gap better than the mattress alone can.
Will the Sleepeezee SmartTemp Seasons super king fit in a loft conversion bedroom?
Allow at least 3m x 2.9m of floor space. In a loft conversion, the sloping ceiling usually decides which wall the headboard can go against. Because this mattress needs regular turning, also check there's enough standing height on both sides to lift and flip a 180cm-wide mattress.
