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.

- More room each than a UK double: Compared with the UK double, the UK king gives each of you 7.5cm more width, which you tend to notice most when you both lie flat on your backs.
- Extra length for a taller partner: At 200cm long, the UK king is 10cm longer than the UK double, so a partner over six foot is less likely to find their feet at the very edge.
- Kinder to different body clocks: If one of you leaves for work hours before the other wakes, the independent springs and the wider surface help keep the early riser's movement on their own side.
- Less floor than a UK super king: We suggest at least 2.7m x 2.9m for the UK king, a little less than the 3m x 2.9m we suggest for the UK super king.
- Breathable across a shared bed: Sharing a bed can run warm, and the Talalay latex with its British wool and silk layer helps even out temperature across the full 5ft x 6ft 6in surface.
This size suits you if...
You share the bed every night and feel cramped on a UK double, one of you is tall enough to find a 190cm mattress too short, or your working hours differ and you want the early riser's movement kept to their own side.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m. If 75cm each still feels tight, choose the UK super king.

Is the Sleepeezee Natural 4000 UK king worth it over the UK double?
For most couples, yes. The UK king is 15cm wider and 10cm longer than the UK double, giving each of you 7.5cm more width. On a mattress whose springs already move independently, that extra space puts a little more distance between you, so one partner's restless night is less likely to become both of yours.
Is a UK king Sleepeezee Natural 4000 long enough if you're over six foot?
It measures 200cm, which is 10cm longer than the UK double and the same length as the UK super king. That makes the UK king the length upgrade in this range, so if your main complaint is feet near the end rather than a lack of width, you don't need to size up further.
Sleepeezee Natural 4000 UK king or super king for a couple?
The UK super king is 30cm wider and gives 90cm each, which is 15cm more each than the UK king's 75cm. Both are the same length. Choose the UK super king only if your room allows at least 3m x 2.9m; otherwise the UK king gives most couples comfortable space.
Will a UK king Sleepeezee Natural 4000 fit a new build master bedroom?
New build bedrooms can feel smaller once wardrobes go in, so measure the floor you actually have left. We suggest at least 2.7m x 2.9m for the UK king, with 3.2m x 3.2m giving you comfortable room to walk around it. Allow for the frame as well as the 150 x 200cm mattress.
Does the UK king size help with partner disturbance on the Sleepeezee Natural 4000?
It helps on two fronts. The pocket springs respond individually, which limits how far movement travels, and the UK king adds 7.5cm each over the UK double, so there is simply more mattress between you. If one of you gets up hours earlier, that combination tends to matter more than it does for solo sleepers.
