Layer Details
Luxurious comfort quilting
A quilted top layer, which gives the sleep surface a softer, more cushioned initial feel.
Soft Foam
A 1cm layer of soft foam that spreads your weight consistently across the surface. It adds a touch of deep comfort before you reach the springs.
Cool Gel Foam
A 1cm layer of cool gel foam with temperature regulation that slows heat build-up in the mattress. In practice, this means you should stay cooler for longer through the night.
Pocket springs
600 individually pocketed springs conform to your body's shape, supporting you where you need it most. Because each spring moves on its own, the design helps prevent the 'roll-together effect' when two people share the bed.
Non Slip Fabric
An anti-slip base fabric that keeps the mattress steady on your bed frame or divan.

Key benefits
- More room each: At 150 x 200cm you each get 75cm, which means an elbow or a turned shoulder is less likely to land on your partner's side.
- Extra length: It is 10cm longer than the UK double, so if you're around 6ft you can stretch out without your feet hanging off the end.
- Less disturbance on early starts: The 600 pocket springs move independently, and the extra width puts more distance between you, so a partner getting up hours earlier should disturb you less.
- Largest size in the range: SleepSoul doesn't make the Paradise in a UK super king, so the UK king gives you the most space this mattress offers.
- Familiar imperial size: In imperial it measures 5ft x 6ft 6in, which helps if your bed frame or headboard is listed in feet.
This size suits you if...
You share the bed every night and wake up when your partner turns over, or one of you is tall and has run out of length on a UK double. It also suits couples who keep different hours and want a little more distance at 5am.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the SleepSoul Paradise UK king big enough for two adults?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. That doesn't sound like much, but you notice it when one of you sleeps with an arm out or turns over often. If you need more than 75cm each, SleepSoul doesn't offer a larger size of the Paradise.
Is the SleepSoul Paradise king size long enough for tall people?
The UK king is 200cm long, 10cm longer than the UK double and the smaller sizes in this range. If one of you is around 6ft or taller, the extra length is often worth more than the extra width. It gives you room for a pillow at the top without your feet pressing against the footboard.
Will the Paradise UK king stop my partner waking me up?
It should help, although no mattress removes disturbance completely. Because the 600 pocket springs move separately, movement spreads less across the bed. The UK king also puts 7.5cm more between each of you than the UK double. This matters if one of you gets up hours before the other.
Does the SleepSoul Paradise come in a super king?
No. The Paradise stops at the UK king, so this is the widest version you can buy. If you really want 90cm each, you'd need a UK super king, and SleepSoul doesn't make one in this model. For most couples, the 75cm each on the UK king is a comfortable middle ground.
Will a SleepSoul Paradise UK king fit a new build master bedroom?
Measure before you buy, because new build rooms often feel smaller once fitted wardrobes are in. We suggest allowing at least 2.7m x 2.9m for a UK king. If your room is tighter than that, the UK double needs at least 2.6m x 2.8m and may leave you more space to walk around the bed.
