Layer Details
Mini comfort springs
A layer of 1,000 mini comfort springs forms the first part of the dual spring system. These smaller springs sit closer to the surface, which means a more responsive, contouring feel where your body presses in most.
Traditional pocketed springs
Beneath them, 1,000 traditional pocketed springs make up the support core. Each spring moves independently, which means support tailored to your shape and less motion transfer across the bed.

Key benefits
- 90cm each for two sleepers: Sharing gives you each the width of a whole UK single, so a partner's turning and stretching rarely reaches your side.
- More room than a UK king: You get 15cm more each than on the UK king, which is the difference between feeling a restless partner and barely noticing them.
- Space for small visitors: If a child climbs in at 3am or the dog settles at your feet, the UK super king still leaves both adults a usable share of the bed.
- Distance plus independent springs: Pocketed springs soften a partner's movement, and at this size there is simply more mattress between you for that movement to fade across.
- Longer than a UK double: At 200cm long, the UK super king is 10cm longer than the UK double, which helps taller sleepers keep their feet on the mattress.
This size suits you if...
You share with a partner who tosses and turns all night, children or a large dog regularly end up in bed with you, or your master bedroom is big enough that a UK king looks undersized against the walls.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or a sloping loft ceiling leaves no full-height wall for the headboard. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Serene 2000 super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each, so a small child who wanders in overnight can squeeze into the middle without anyone ending up on the edge. If a child sleeps with you every night, the space will feel tighter, but no mainstream UK size gives you more width than the UK super king.
Serene 2000 king or super king for a restless partner?
If your room allows it, choose the UK super king. It is 30cm wider than the UK king and gives you 15cm more each, and that distance does more for a restless partner than any comfort layer. Both sizes are the same length. The UK king needs at least 2.7m x 2.9m, and the UK super king needs at least 3m x 2.9m.
Will a super king Serene 2000 fit in a loft conversion bedroom?
It can, but the slope usually decides where the bed goes. You need a full-height wall for the headboard end, and the floor space has to reach at least 3m x 2.9m once you exclude the low sections you can't stand up in. Check that the door can swing open fully past the bed's corner as well.
Is the Sleepeezee Serene 2000 super king good for sharing with a large dog?
It's the most practical size for that. At 180cm wide, a big dog can lie across the foot or along one side while both of you keep a reasonable share. The independent pocketed springs also mean a dog shifting position at night is less likely to jolt whoever is sleeping furthest away.
How much longer is the Serene 2000 super king than a double?
The UK super king is 10cm longer than the UK double and 45cm wider. It also gives you 22.5cm more each when two of you share. If you or your partner are tall and your feet reach the end of a UK double, the extra length makes a difference.
