Layer Details
Cover
Soft-touch Pisa fabric with cooling technology, which means the surface feels cool when you get in and resists heat transfer through the night. A sensible pairing with memory foam, which can otherwise run warm.
Memory foam
A body-conforming upper layer that moulds to your shape, giving that slow, cradled feel. It sits at the top as a pillow top, so it is the first thing you feel.
Eco foam
A high-density eco foam layer aimed at targeted pressure relief. In practice, that means less build-up at heavier points like hips and shoulders.
Microsprings
2,000 microsprings for finely tuned, body-responsive support. These small springs react to detail the main unit can miss, which means more even contouring.
Pocket springs
The Sleep Sound Pocket+ system uses 1,000 individually nested springs in the king size. Each spring moves independently, so your partner's movement is less likely to disturb you.
Insulating fillings
The springs are encased in insulating fillings for superior edge support. That gives you a firmer perimeter, so you can use the full width of the bed.

Key benefits
- Room to stop negotiating: Each of you gets 75cm of width, 7.5cm more than on a UK double, which means fewer elbows and less quiet competition for the middle of the bed.
- Length for a taller partner: At 200cm (6ft 6in) the UK king is 10cm longer than a UK double, so a tall sleeper's feet stay on the mattress rather than hanging off the end.
- Movement kept on one side: The UK king version holds 1,000 independently moving pocket springs plus 2,000 microsprings, so a partner turning over is less likely to register on your side.
- Usable edges: Insulating fillings firm up the perimeter, which means you can sleep near the edge of the 150cm width without feeling you might roll off.
- A cooler start for two: Two bodies share more warmth than one, and the Pisa cover is designed to feel cool when you get in, which helps offset memory foam's tendency to run warm.
This size suits you if...
You share the bed every night and keep disturbing each other, one of you is over 6ft and tired of cold feet poking past the end, or you work different hours and want the early riser's movements to stay on their own side of the mattress.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes and drawers are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
How many springs are in the Sleep Sound Cooler Memory 3000 UK king?
Furniture Village states the UK king holds 1,000 pocket springs in its Pocket+ system, plus 2,000 microsprings above them. Spring counts usually differ between sizes, so if you are comparing against a smaller size of this mattress, check the brand's own figures for that size before buying.
Is the Sleep Sound Cooler Memory 3000 king long enough for a tall person?
It is 200cm long, or 6ft 6in, which is 10cm more than a UK double. If one of you is over 6ft, that extra length is often the bigger upgrade than the width, because it lets you lie straight without your feet reaching past the edge.
Will I feel my partner move on a UK king memory foam hybrid?
Less than on a smaller bed, for two reasons. You each have 75cm of your own space, and the pocket springs move independently, so a partner getting up for an early shift is less likely to jolt you. Memory foam also absorbs some movement, although nothing removes it entirely.
Is it worth going from a UK double to a UK king in this mattress?
For most couples, yes. You gain 7.5cm each and 10cm of length. The trade-off is room: we suggest at least 2.7m x 2.9m for the UK king against 2.6m x 2.8m for the UK double. Measure a new build master bedroom with its wardrobes fitted, as it can feel smaller than the plans suggest.
