Layer Details
- Pillow top. A pillow top sewn onto the sleep surface, which means an extra layer of cushioning before you reach the springs. It gives the mattress its plush, sink-in first impression.
- Knitted cover. A soft knitted cover over the top of the mattress. Knitted fabric stretches more than woven, so it flexes with the layers beneath rather than pulling the surface taut.
- Springs. 2,500 pocketed springs in total: 1,500 mini comfort springs and 1,000 traditional pocketed springs. The mini springs respond to smaller pressure points while the full-size springs below provide the core support.

- Real distance from a restless partner: You each get 90cm, which means a partner who turns over all night is much further from you than on a smaller bed.
- More room than the UK king: The UK super king is 30cm wider than the UK king at the same length, giving each of you 15cm more width.
- Space when the household piles in: When a small child or the dog climbs in, 180cm of width means the adults are less likely to end up clinging to the edges.
- The same soft feel edge to edge: The pillow top and 1,500 mini comfort springs run across the full sleep surface, so side sleepers get the same cushioned feel wherever they end up.
- In proportion in a large bedroom: In a period property or a generous master bedroom, a 6ft x 6ft 6in bed fills the space properly where a smaller bed can look a little lost.
This size suits you if...
You share the bed every night with someone who fidgets, kicks or gets up early, you regularly have a child or dog joining you by morning, and your bedroom comfortably clears our suggested 3m x 2.9m with space left for bedside tables.
Consider another size if...
Your bedroom is under 3m x 2.9m, or the door swing and landing turns are already tight. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee Serene 2500 super king big enough for two adults and a child?
It's the most room this mattress offers, at 180 x 200cm with 90cm each for two adults. A small child in the middle will squeeze that, but far less than on the UK king. Because the feel is medium soft, expect the surface to give a little where bodies gather, which most owners of softer mattresses simply get used to.
Sleepeezee Serene 2500 UK super king or UK king for a couple?
The UK super king is 30cm wider and the same length, so you each gain 15cm. If one of you is a restless sleeper, that extra width is the main reason to size up. The trade-off is space: we suggest at least 3m x 2.9m for the UK super king against at least 2.7m x 2.9m for the UK king.
Is a super king Serene 2500 a good idea if my partner moves around a lot?
Yes, and the width does most of the work here. With 90cm each, a partner who tosses and turns has more room to do it before they reach your side. The soft pillow top then gives you a cushioned surface to settle back into, which suits side sleepers in particular.
Can I fit the Sleepeezee Serene 2500 super king in a loft conversion bedroom?
Possibly, but measure carefully first. The slope of the ceiling usually decides which wall the bed goes against, and at 200cm long and 180cm wide there's little flexibility. We suggest a floor space of at least 3m x 2.9m, with enough full headroom along the side where you'll get in and out.
Will the Serene 2500 super king work if our large dog sleeps on the bed?
The 180cm width gives a dog room to settle without pushing either of you towards the edge, which a UK king struggles with. Bear in mind the medium soft feel: a heavy dog lying in one spot every night may leave the surface there a little more compressed than the rest.
