Layer Details
Top Layer
A sumptuously soft pillow-top of plush filling, which means extra cushioning the moment you lie down. This is what gives the mattress its gentle initial feel.
Soft Foam
A soft foam layer that distributes your weight consistently. In practice, that means fewer pressure points at your hips and shoulders.
Soft Foam
A second soft foam layer continues that even weight distribution. Together the two add depth to the comfortable, cradling feel.
Memory Foam
A memory foam transition layer that lets you sink in slightly while minimising movement. It bridges the soft upper layers and the springs below.
Springs
800 pocket springs conform to your body's shape, supporting you where you need it most. Because each spring moves independently, they help prevent the roll-together effect on shared beds.
Non Slip Fabric
An anti-slip base fabric that keeps the mattress steady on your bed frame. A small detail, but it stops annoying shifting over time.

Key benefits
- 90cm each for two: At 6ft x 6ft 6in, two sharers get 90cm each, so a restless partner's turning reaches you as distance rather than a jolt.
- Room for small visitors: Children climbing in during the night can settle between you without either adult losing their side, something a UK double struggles to manage.
- Movement stays on one side: The 800 pocket springs move independently, so on a bed this wide one person's shifting stays largely on their own half.
- The same soft top across the full width: The plush pillow-top covers all 180cm, so whoever ends up in the middle lies on the same cushioned surface as everyone else.
- In scale with a large room: In a spacious master or a high-ceilinged period bedroom, a UK super king looks properly proportioned where a UK king can seem a little lost.
This size suits you if...
You share with a partner who moves a lot in the night, your children or a large dog regularly end up in bed with you, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your room is under 3m x 2.9m, or door swings and tight landing turns leave little clearance. We'd recommend the UK king instead, which gives 75cm each and needs at least 2.7m x 2.9m.

FAQ's
Is the SleepSoul Bliss super king big enough for two adults and a child?
For a child who wanders in at night, usually yes. Two adults get 90cm each on the UK super king, so a small visitor can settle in the middle without anyone clinging to the edge. The soft pillow-top runs the full width, so the middle feels much the same as either side.
Will a restless partner disturb me on a super king pillowtop mattress?
Less than on a smaller size. Distance does most of the work: on the UK super king you each have 90cm, so a partner who turns over is further away. The 800 pocket springs also move independently, and the memory foam layer helps soak up movement, although you may still feel a little when they get in or out.
SleepSoul Bliss king or super king: which should I get?
The UK super king is 30cm wider than the UK king and the same length. The UK king gives 75cm each for two sharing, and the UK super king gives 15cm more each. We suggest at least 2.7m x 2.9m for the UK king and 3m x 2.9m for the UK super king, so let your room make the final call.
Can a super king fit in a loft conversion bedroom?
Often, but the slope decides where it goes. At 200cm long, the head of the bed needs a full-height wall, so measure the usable floor rather than the whole room and check it still clears 3m x 2.9m. This mattress is 32cm deep, so allow for sitting up under a lower ceiling.
How do you rotate a SleepSoul Bliss mattress in super king size?
Pillow-tops can't be flipped, only turned head to foot. At 180cm wide, the UK super king is awkward for one person to turn, so ask someone to help and slide it partly off the frame before you turn it. It is easier with the bedding off and the bedside tables moved back.
