Layer Details
- Silk. A light, soft silk layer sits at the top, which means the surface feels gentle and luxurious the moment you lie down. It is a comfort layer rather than a support one, so it shapes the initial feel of the mattress.
- Wool. Beneath the silk, wool adds a soft, cushioned feel and helps regulate temperature naturally. It suits people who want a traditional, natural mattress rather than a synthetic one.
- 2000 Pocket Springs. Each of the 2,000 springs sits in its own fabric pocket and works independently, which means support adapts to your body shape and pressure points. This also helps limit motion transfer if you share the bed.
Layer details from mattressnextday.co.uk product page, September 2026.
- 90cm of your own: Each of you gets 90cm of width, which means a partner who fidgets or sprawls is far less likely to reach your side of the bed.
- More room than a UK king: The UK super king is 30cm wider than the UK king at the same length, giving each sleeper 15cm more space.
- Springs that keep movement local: The 2,000 independent pocket springs limit motion transfer, and across a 180cm surface that means a small child climbing in at 3am is less likely to wake you both.
- Space for the household: If children or a large dog regularly join you, the extra width means the adults still keep a proper sleeping space rather than clinging to the edges.
- Suits a grand room: In a period bedroom or a large master, a UK super king fills the space in proportion, where a smaller bed can look a little lost.
This size suits you if...
You share the bed with a genuinely restless partner and want real distance between you, or children and pets often end up in with you at night. It also suits you if 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 two of you sleep still and close together. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee Wool Supreme super king big enough for two adults and a child?
Yes, for occasional night visits. The UK super king gives two adults 90cm each, so a small child tucked between you still leaves each adult usable space. The pocket springs also help, because a wriggling child is less likely to disturb the side of the bed they are not lying on.
Sleepeezee Wool Supreme super king vs king: how much extra space do you get?
The UK super king is 30cm wider than the UK king, and both are the same length. That works out at 15cm more for each person sharing: 90cm each on the UK super king against 75cm each on the UK king. If neither of you is restless, the UK king may be enough.
What size bedroom do I need for a UK super king Wool Supreme?
We suggest at least 3m x 2.9m for a UK super king. In a loft conversion, check that the sloping ceiling leaves a full-height wall for the headboard. If your room falls short, the UK king needs at least 2.7m x 2.9m.
Is a super king mattress worth it if my partner is a restless sleeper?
Usually, yes. With a restless partner, physical distance tends to help more than any soft top layer. The UK super king's 90cm each puts real space between you, and the Wool Supreme's independent pocket springs keep much of their movement on their own side.
Can a large dog sleep on a Sleepeezee Wool Supreme super king with two people?
A UK super king is the most realistic size for this, because at 180cm wide a large dog can settle at the foot or to one side without taking all of your 90cm. The medium feel and soft wool top will show wear where a dog lies nightly, so a mattress protector is sensible.
