Layer Details
- Pillow Top. A plush layer of fillings sits on top of the mattress, which means a softer initial feel before you reach the firmer support below. It gives the surface that cushioned, sink-in-slightly quality without needing a separate topper.
- Belgian Damask Viscose Sleep Surface. A silky, highly breathable cover that helps keep the sleep surface feeling fresher. It's the layer your skin is closest to, so the softness here matters more than you might expect.
- Natural Talalay Latex. 100% natural Talalay latex contours to your body, which means pressure relief with a responsive, slightly buoyant feel rather than a slow sink. It's also hypoallergenic and highly breathable, a genuine plus for allergy sufferers and hot sleepers.
- Natural Latex Layer. Two further layers of natural latex cushion key areas such as the shoulders, hips and lower back. They provide responsive pressure relief without excessive sink, so you stay supported rather than swallowed.
- Sustainably Sourced British Wool & Silk. A naturally soft, lightweight blend of British wool and silk that offers excellent insulation. In practice that means it helps keep you cool in summer and warm in winter, evening out temperature swings through the year.
- Polycotton Comfort Layers. Polyester and polycotton fibre layers add cushioning with good recovery and rebound. This helps the comfort layers keep their shape over time rather than compressing into dips.
- High-Density Polyester Support Layer. A high-density polyester layer beneath the comfort fillings helps maintain the mattress's structure. Think of it as scaffolding that protects the softer layers above and supports long-term durability.
- 4000 Pocket Springs. A 4000 pocket spring system combines 1000 traditional pocket springs with 3000 mini comfort springs, each responding independently to your movements. For couples, that means less disturbance when one of you shifts or gets up in the night.

- All the extra goes into width: The UK super king is 30cm wider than the UK king but the same length, so every added centimetre sits side to side, where two sleepers actually need it.
- Distance from a restless partner: The independent pocket springs limit motion, but the bigger help at this size is 90cm each, which means a partner's tossing happens further away from you.
- Space when the household piles in: When a child or a large dog arrives in the night, a UK super king leaves two adults a proper share rather than a thin strip by the edge.
- Breathable with extra bodies: Talalay latex and the British wool and silk blend are breathable, which counts for more when a UK super king is holding more people and more body heat.
- In proportion in a big room: In a period house or a generous master bedroom, the UK super king fills the floor in proportion where a UK king can look slightly undersized.
This size suits you if...
You share with a partner who moves a lot, or children and the dog regularly end up in bed with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or a tight door swing and landing turn make a 6ft mattress awkward. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

Is the Sleepeezee Natural 4000 UK super king big enough for two adults and a child?
For occasional visits, yes. With 90cm each for two adults, there is room to make space for a small child without anyone clinging to the edge. The Medium Firm feel and responsive latex also mean a child's weight doesn't create a dip that rolls you towards the middle. For three sharing every night, expect it to feel full rather than roomy.
How much more space does the Sleepeezee Natural 4000 super king give than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length. Shared between two people, that gives you 15cm more each: 90cm on the UK super king against 75cm on the UK king. If legroom is your concern, sizing up won't change it.
Will the Sleepeezee Natural 4000 in a UK super king fit my bedroom?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling comfortable once you add bedside tables. In a loft conversion, check ceiling height too: the slope often decides which wall the bed can go against, and you need to be able to sit up on both sides.
Is the Sleepeezee Natural 4000 super king good if my partner is a restless sleeper?
It's a sensible pairing. The 4000 pocket springs move independently, so less of your partner's movement travels across the bed. At this size you also get 90cm each, and that physical distance does more for a genuinely restless sleeper than any comfort layer can. For light sleepers, the UK super king gives both of those benefits together.
Is it worth going from a double to the Sleepeezee Natural 4000 super king?
If you share, the difference is large. The UK super king is 45cm wider and 10cm longer than the UK double, giving 22.5cm more each: 90cm per person instead of 67.5cm. That is a very different night for a couple, but the room has to fit it, and super king bedding adds to the cost.
