Layer Details
Graphite memory foam
A memory foam layer with cooling graphite that helps relieve pressure and regulate temperature. It adds cushioning over the firm feel and helps limit heat build-up.
Individually wrapped pocket springs
Individually wrapped springs sit beneath the memory foam. Each spring works on its own, which helps reduce partner motion when one of you moves.

Key benefits
- A full 6ft of width: At 180 x 200cm, or 6ft x 6ft 6in, the UK super king gives you 90cm each, which means a restless partner can turn over without reaching your side.
- Distance plus independent springs: Individually wrapped pocket springs move on their own, and the extra gap a UK super king puts between you makes a partner's fidgeting far less likely to wake you.
- Room for night-time visitors: When a child wanders in or a large dog settles at the foot, a UK super king still leaves both adults enough room to stay put.
- Firm support across a wide bed: The firm feel keeps you level across the whole width, with a graphite memory foam top easing pressure slightly, which suits back sleepers sharing a big bed.
- Usable edges: Edge-to-edge support lets you sleep on the outer strip of a UK super king too, so the 90cm each is space you can use.
- A clear step up from the UK king: Moving up from the UK king adds 30cm of width and 15cm more each for two people, while the 200cm length stays the same.
This size suits you if...
You share the bed every night with a partner who tosses and turns, children or a dog regularly end up in with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or your stairs and landing are too tight for a bed this wide. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Nova 1800 super king big enough for two adults and a child?
It's the roomiest size of the Nova 1800. Two adults get 90cm each across the 180cm width, so a young child climbing in at night can usually fit between you without anyone ending up on the edge. Edge-to-edge support means the outer strip is usable too, which helps when space gets shared.
How big a bedroom do I need for a super king Sleepeezee Nova 1800?
We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m if you want bedside tables and room to walk round. In a loft conversion, measure where the ceiling slopes first, because the wall with full head height usually decides where the bed can go.
Should I get the Nova 1800 in a super king or king for a restless partner?
A UK super king gives you 15cm more each than the UK king: 90cm each against 75cm. The pocket springs help limit movement, but distance does more of the work. If your partner's turning already wakes you on a UK king, choose the UK super king, provided your room allows at least 3m x 2.9m.
Will a Sleepeezee Nova 1800 super king fit up my stairs?
At 180 x 200cm and 29cm deep, the UK super king is a large, rigid item to carry upstairs. Narrow cottage stairs and tight landing turns are the usual problems at this width. Measure the landing turn and the bedroom door first, then compare the retailers listed on this page.
What bedding fits a Sleepeezee Nova 1800 super king?
You'll need UK super king sheets for the 180 x 200cm surface and a 260 x 220cm duvet. Because the mattress is 29cm deep, check that fitted sheets have deep enough pockets before buying. If you're moving up from a UK king, your current bedding won't fit.
