Layer Details
- Cover. A soft, woven viscose cover sits on top. Viscose is smooth and breathable, so the surface feels gentle against bedding rather than clammy.
- Comfort fillings. Beneath the cover sit generous natural fillings of British wool and alpaca wool. Wool helps regulate temperature, which means it can feel warmer in winter and cooler in summer than synthetic fillings.
- Mini Pocket Springs. A layer of small, individually cased springs adds comfort close to the surface. These respond to lighter pressure, giving soothing relief at the shoulders and hips.
- Pocket Springs. The main support comes from individual springs encased in cloth pockets. Each one adapts to movement separately, so support is distributed to each part of your body rather than the whole bed tilting when your partner turns over.

- Real distance from a restless partner: With 90cm each, the independently moving pocket springs have less to absorb, because a partner who kicks and turns is simply further away from you.
- Space when the family piles in: If a small child wanders in most nights, the UK super king gives 22.5cm more each than the UK double, so two adults and a little one can all stay flat.
- Room for a large dog on the bed: If your dog sleeps at your feet as a matter of routine, the extra 30cm of width over the UK king stops you curling around them.
- Wool fillings across a bigger surface: More bodies in the bed means more warmth, and the breathable British wool and alpaca fillings help keep a crowded UK super king from feeling stuffy.
- Looks in proportion in a large bedroom: In a period property with high ceilings or a generous master bedroom, the UK super king fills the space properly where a UK king can look a little lost.
This size suits you if...
You share the bed every night with someone who moves a lot, a young child or a large dog regularly joins you, or your bedroom is at least 3m x 2.9m and a UK king would look undersized in it.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m or your landing is tight. We'd recommend the UK king instead, which is 30cm narrower; allow at least 2.7m x 2.9m for it.

Is the Sleepeezee Centurial 01 4500 UK super king big enough for two adults and a child?
For occasional night-time visits, yes. The UK super king gives two adults 90cm each, and that margin is what lets a small child squeeze in without anyone ending up on the edge. If your child joins you most nights as they get older, the space will tighten, but the UK super king is still the widest option in this range.
Sleepeezee Centurial 01 4500 super king or king for a restless partner?
If a partner's movement regularly wakes you, choose the UK super king. It gives 15cm more each than the UK king, at 90cm against 75cm per person. The pocket springs already limit how far movement travels, but a little extra distance is often what makes the real difference for light sleepers.
Will a Sleepeezee Centurial 01 4500 UK super king fit my bedroom?
We suggest a room of at least 3m x 2.9m, and nearer 3.5m x 3.2m is more comfortable. Check which way the door swings and whether you can still walk round both sides. In a loft conversion, the sloping ceiling often decides which wall the bed can go against, so measure the full-height floor area.
Can I get the Sleepeezee Centurial 01 4500 super king upstairs?
At 180cm wide, a single-piece UK super king can struggle on tight landing turns and narrow staircases. Sleepeezee doesn't publish a weight or handling guidance for this size here, so check the route from the front door to the bedroom before buying and ask the retailer whether the mattress can be flexed or carried on its side.
How much extra space does the UK super king give over a double?
The UK super king is 45cm wider and 10cm longer than the UK double. For two people sharing, that works out at 22.5cm more each, rising from 67.5cm to 90cm per person. If you're moving up from a UK double, the difference at night is considerable. Remember that super king sheets and a 260 x 220cm duvet add to the cost of the bed.
