Layer Details
- Pillow Top. A deep pillow top filled with cool gel memory foam, which means a cushioned surface that actively draws heat away from your body. It helps regulate your temperature through the night rather than letting warmth build up.
- Cool Gel Memory Foam. This layer adds pressure relief and support, moulding to your shape for a more comfortable night. It regulates body temperature better than standard memory foam, so hot sleepers get the contouring without the heat.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means support and pressure relief exactly where your body needs it. It also helps limit motion transfer if you share the bed.
- Knitted Cover. A soft, breathable knitted cover that lets air move through the surface. That helps keep you at an even temperature all night long.

- 90cm each for two sharing: Each of you gets 90cm, which means you can turn over, sprawl or get up early without nudging the person beside you.
- Room for a small visitor: When a child climbs in after a bad dream, a UK super king leaves the adults a usable share instead of clinging to the edges.
- Distance plus independent springs: The pocket springs limit motion transfer, and 15cm more each than the UK king puts extra space between you and a restless sleeper.
- Cooler with more bodies in bed: Cool gel foam in the pillow top helps draw heat away, which is useful when two adults, a child or a dog share one surface.
- Firm support across the full width: The firm, orthopaedic feel holds a heavier sleeper and a lighter one level, so neither of you rolls towards a dip in the middle.
This size suits you if...
You share with a partner whose tossing and turning keeps waking you, or your children or a large dog regularly end up in the bed by morning. It also suits a big master bedroom where a UK king would look lost against the wall.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m. We'd recommend the UK king instead, which is 30cm narrower and needs at least 2.7m x 2.9m.

Is the Coolology 3000 UK super king big enough for two adults and a child?
For occasional night visits, yes. The UK super king gives 90cm each to two sharing, so a small child can fit between you without either adult losing the whole of their side. The firm surface also means nobody sinks towards the middle, although a child who joins every night will still eat into that space.
Will a restless partner disturb me on a super king Coolology 3000?
Much less than on a smaller size. The pocket springs move independently, so movement travels less across the mattress, and the UK super king adds 15cm more each than the UK king. If your partner is a genuinely heavy fidgeter, that extra distance often helps more than any comfort layer could.
Coolology 3000 super king or king: which should I buy?
Choose the UK super king if you want the most space and your room is at least 3m x 2.9m. The UK king is 30cm narrower but the same length, and we suggest at least 2.7m x 2.9m for it. If the room is borderline, the UK king leaves more floor to walk around.
Is the Coolology 3000 in a UK super king hard to move or rotate?
It can be. This is a heavy 32cm hybrid, and at 180cm wide it is awkward for one person to turn. SleepSoul doesn't publish a weight for the UK super king, so plan on two people for rotating it and for carrying it into the bedroom.
What should I measure before ordering the Coolology 3000 UK super king?
Check the bedroom first: allow at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. Then measure door swing and any tight landing turns, because a 180 x 200cm hybrid this deep does not bend easily. In a loft conversion, the sloping ceiling may decide which wall the bed goes on.
