Layer Details
Pillow-top layer
A 2cm layer of soft foam in a quilted pillow-top cover. It gives the surface a plush, cushioned feel, so the mattress feels softer on top than the medium soft rating alone suggests.
CoolGel layer
A 3cm layer of CoolGel foam that SleepSoul says slows down heat build-up in the mattress. That should help you stay more comfortable through the night if you tend to sleep warm.
Mini pocket springs
An extra layer of 1200 mini pocket springs. They add comfort and support just beneath the foam, so the surface responds to your body more closely.
Pocket spring base
800 pocket springs that SleepSoul says conform to your body's shape. They support you where you need it most and form the main support in the mattress.

Key benefits
- Real distance from a restless partner: With 90cm each, a partner who kicks or turns all night is a full arm's length further away, and no comfort layer can match that much separation.
- 15cm more each than a UK king: The UK super king is 30cm wider than the UK king at the same length, so each sleeper gains 15cm without the bed reaching further into the room.
- Room for night-time visitors: When a small child climbs in or the dog settles at your feet, the 180cm width means both adults keep a usable share of the cushioned pillow-top surface.
- A cushioned feel across the whole width: SleepSoul rates it medium soft, so the extra width is plush from edge to edge, which suits two side sleepers who both like to sink in a little.
- Proportioned for a large master bedroom: In a high-ceilinged period bedroom or a spacious new build master, the 30cm deep UK super king fills the space properly where a UK king can look lost.
This size suits you if...
You share the bed with a partner who tosses and turns, your children or pets regularly end up in bed with you, or your bedroom is large enough that a UK king would leave the wall looking bare.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or both of you are heavier sleepers who need firmer support. In a tighter room, we'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will the SleepSoul Heaven 2000 in a UK super king fit my bedroom?
Allow at least 3m x 2.9m for the 180 x 200cm UK super king, although around 3.5m x 3.2m feels comfortable once bedside tables are in. In a loft conversion, measure where the ceiling slopes first, because the headroom usually decides which wall the bed can go against.
How much extra space does a UK super king give over a UK king?
The UK super king is 30cm wider than the UK king, and the two are the same length. Shared between two people, that works out at 90cm each on the UK super king against 75cm each on the UK king, so you each gain 15cm.
Is a UK super king big enough for two adults and a child?
Two adults get 90cm each on a UK super king, which leaves enough slack for a toddler who wanders in overnight without one parent ending up on the edge. If it happens most nights rather than occasionally, the extra width over a UK king makes the biggest difference.
What bedding do I need for a 30cm deep UK super king mattress?
You'll need UK super king sheets and a 260 x 220cm duvet. At 30cm deep, with a pillow top, this mattress is thicker than many, so choose a fitted sheet with deep pockets or the corners will keep pulling off. Bedding at this size also tends to cost more.
Will a super king mattress fit up my stairs?
Measure the tightest landing turn and how far the bedroom door swings open before ordering, because a 180cm wide mattress struggles in narrow hallways. SleepSoul doesn't publish a weight for this mattress, so check with the seller about delivery to an upper floor, then compare the retailers listed on this page.
