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.

- Fits the bedrooms most couples actually have: At 135 x 190cm, it leaves space for bedside tables on both sides, provided the room is at least 2.6m x 2.8m, which is our suggested minimum.
- Less disturbance at close quarters: With 67.5cm each you sleep close together, and pocket springs that move independently mean a partner turning over is less likely to jolt your side of the bed.
- Cooler when two of you share: Two people in a double build up more warmth, and the cool gel memory foam in the pillow top is designed to draw that heat away rather than trap it.
- Firm support on both sides: The firm, orthopaedic feel suits couples who both like support, although a lightweight side sleeper may find it presses a little on hips and shoulders.
- Simple to dress: Double sheets and a 200 x 200cm double duvet fit the UK double, and both are sold widely at every level of the market.
This size suits you if...
You share the bed with a partner who also prefers a firm feel and your bedroom is at least 2.6m x 2.8m, or you're furnishing a guest room for visiting couples, or a first flat where the bed must share floor space with a wardrobe and drawers.
Consider another size if...
One of you sprawls across the bed, or you're both tall enough to feel the end of a 190cm mattress. We'd recommend the UK king instead, which is 10cm longer; we suggest at least 2.7m x 2.9m for it.

Is the Coolology 3000 UK double wide enough for two hot sleepers?
You each get 67.5cm, which is close contact for two people who run warm. The cool gel memory foam in the pillow top and comfort layer is designed to pull heat away from your body, and the knitted cover lets air move through the surface. If you want more space between you as well, the UK king gives 75cm each.
Will a SleepSoul Coolology 3000 UK double fit in a small second bedroom?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable. In a smaller second bedroom that also holds a wardrobe and drawers, measure door swing and drawer clearance before you commit. If the room falls short, the UK double will feel cramped.
How much smaller is the Coolology 3000 UK double than the UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king, giving each sleeper 7.5cm less width. For the UK king we suggest a room of at least 2.7m x 2.9m, so it needs a slightly larger bedroom than the UK double does.
Is the Coolology 3000 UK double long enough for tall couples?
The UK double is 190cm long, which is 6ft 3in. That suits most adults, but if either of you is tall enough for your feet to reach the end, the UK king adds 10cm of length as well as extra width.
Is the SleepSoul Coolology 3000 in a UK double good for a guest room?
For visiting couples, yes, as long as your guests are happy on a firm mattress. The UK double gives two people room to share without taking over a spare room, and the gel foam helps if guests sleep warm in an unfamiliar bed. Guests who like a soft, sink-in feel may find it a little unforgiving.
