Layer Details
- Top Layer. A 2cm pillow-top of plush filling, which means a soft, cushioned first impression before you reach the firmer support below. It takes a slight edge off the medium/firm feel.
- Cool Gel Foam. A 3cm layer of cool gel foam that slows heat build-up in the mattress. If you're a hot sleeper, this should help you stay comfortable for longer through the night.
- Pocket Springs. 1000 individual pocket springs that conform to your body's shape, supporting you where you need it most. Because each spring moves independently, they also help prevent the roll-together effect that pushes couples into the middle.
- Mini Springs. An additional 2000 mini pocket springs sit within the build for extra comfort and support. These smaller springs respond to lighter pressure, which means a more adaptive feel close to the surface.
- Base. A non-slip fabric base for additional stability. In practice this helps the mattress stay put on slatted or divan bases.

- 90cm each for two: With 90cm of width per person, a restless partner's turning is far less likely to reach you, which means fewer broken nights for the lighter sleeper.
- Springs that move independently: The 1000 pocket springs respond separately, so a child climbing in on one side shouldn't tip the other sleeper towards the middle of this 180cm-wide bed.
- 15cm more each than a UK king: Compared with the UK king, you gain 30cm of width at the same 200cm length, which works out at 15cm more each for two sleepers.
- In proportion in a large room: In a period bedroom or a generous master, a UK super king looks settled against the wall where a smaller bed can look a little lost.
- Cooler with company: More bodies in the bed means more warmth, so the 3cm cool gel foam layer helps slow heat build-up when a child or dog joins you overnight.
This size suits you if...
You share with a partner who tosses and turns and want real distance between you, or children and a large dog regularly end up in the bed overnight and everyone still needs their own share of the mattress.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m, or the bed would block a door swinging open. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the SleepSoul Heaven 3000 super king big enough for two adults and a child?
It's the most room this mattress offers: 180cm across, with 90cm each for two adults before a child arrives. A small child tucked in the middle takes some of that space, but the independent pocket springs should help stop anyone rolling into a dip in the centre.
SleepSoul Heaven 3000 super king or king for a restless partner?
If your partner's movement is the main problem, the UK super king is the better pick. It is 30cm wider than the UK king at the same length, giving 15cm more each. Pocket springs help limit movement, but physical distance does more for a light sleeper than a comfort layer alone.
Will a super king Heaven 3000 fit in a loft conversion bedroom?
Often, but the sloping ceiling usually decides which wall the bed goes against. We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. If the slope eats into your usable floor, the UK king may suit you better, and we suggest at least 2.7m x 2.9m for that size.
How much wider is the SleepSoul Heaven 3000 super king than a double?
The UK super king is 45cm wider and 10cm longer than the UK double. For two people sharing, the UK double gives 67.5cm each, so the UK super king gives 22.5cm more each, which is the difference between brushing elbows and having a side of your own.
Is the Heaven 3000 in super king good if my dog sleeps on the bed?
For a large dog sleeping with you most nights, the UK super king makes the most sense of this mattress's sizes, since 90cm each leaves some room at the foot or between you. The non-slip fabric base also helps the mattress stay put when a dog jumps on and off.
