Layer Details
Pillow Top
An additional layer of plush fillings sewn onto the top, which means a softer initial feel when you lie down. You get cushioned comfort without changing the medium firm support underneath.
Knitted Cover
A soft knitted cover that's breathable, helping to keep you at an even temperature through the night.
Body-Contouring Memory Foam
Super-soft memory foam that adapts to your shape, easing pressure on your joints. Its slow response minimises bounce, so you're less likely to feel a partner moving.
Soft Polyester Comfort Layers
Soft polyester layers that add cushioning without compromising the medium firm feel.
High-Density Polyester Support Layer
A denser polyester layer beneath the comfort fillings, which helps the mattress hold its structure and last longer.
4000 Pocket Spring System
1000 traditional pocket springs combined with 3000 mini comfort springs. Each spring moves independently, which means support that follows your body rather than pushing back as one flat surface.

Key benefits
- Distance and stillness together: The 90cm each for two sharers adds space, and the slow-response memory foam dampens bounce, so a partner who turns over often is less likely to wake you.
- Room when a child climbs in: When a little one arrives after a bad dream, the 180cm width lets them settle between you without either adult ending up balanced on the edge.
- A patch of its own for the dog: If a large dog sleeps on the bed every night, the extra 30cm over the UK king gives it somewhere to lie without claiming half of your side.
- In proportion with a big bedroom: In a high-ceilinged period bedroom or a generous master, a UK super king fills the floor sensibly where a UK king can look slightly lost.
- Same length as the UK king: At 200cm long, the UK super king matches the UK king for length, so moving up here gains you width rather than legroom.
This size suits you if...
You share the bed every night with a partner who tosses and turns, children or a large dog regularly join you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or your doorways and landing turns are tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Memory 4000 super king good if my partner is restless?
Yes, for most couples. You each get 90cm, which is 15cm more each than the UK king, and the memory foam's slow response keeps movement from travelling far. A very active sleeper may still be felt now and then, but distance plus damped bounce gives you a better chance than any narrower size of this mattress.
Sleepeezee Memory 4000 super king or king: which should I buy?
Choose the UK super king if your room allows at least 3m x 2.9m and you want every bit of width: it is 30cm wider than the UK king at the same length. If your room is closer to 2.7m x 2.9m, the UK king is the better fit and still gives you 75cm each.
Can two adults and a child share a Sleepeezee Memory 4000 super king?
For occasional nights, yes. The UK super king is the widest size this mattress comes in, so a small child who wanders in can lie between you without anyone being pushed to the edge. If it happens most nights and the child is growing, expect the bed to feel a little snugger over time.
Will the Sleepeezee Memory 4000 in super king fit a loft conversion bedroom?
Only if a full-height wall can take the 180cm width at the head end. Sloping ceilings usually decide where the bed goes, and at 30cm deep plus a base, sitting up under a low slope can feel cramped. Measure floor space at standing height, and check the stair turns, as a 180 x 200cm mattress is awkward on tight corners.
Is the Sleepeezee Memory 4000 super king big enough for a large dog as well?
For most couples, yes. A large dog on a UK king often takes over one sleeper's space, whereas the extra 30cm of width here leaves room for it along one side or across the foot. The pillow top's plush fillings are soft, so a mattress protector is sensible if paws and claws are involved.
