Layer Details
- Copper Infused Memory Foam. The top layer uses memory foam infused with copper, which helps reduce heat build-up and moves body heat away more quickly, so you should feel noticeably cooler than on standard memory foam. Sleepeezee also credits the copper with antimicrobial properties.
- White Fibre Filling. A white fibre filling sits between the foam and the springs, cushioning spring movement so you feel a smoother surface rather than individual coils. It also helps reduce allergens, a small but welcome touch for sensitive sleepers.
- 800 Pocket Springs. The base is 800 traditional pocket springs that adjust independently, which means support that responds to your body shape rather than the whole bed moving as one. That independence also helps limit disturbance when a partner shifts position.
Layer details from sleepeezee.com product page, September 2026.
- Distance from a restless partner: With 90cm each, a partner who kicks and turns is further away, and the independently moving pocket springs limit how much of that motion reaches your side.
- Space when a child climbs in: The UK super king gives 22.5cm more each than the UK double, so a small visitor at 3am doesn't leave either adult clinging to the edge.
- Wider than a UK king, same length: You gain 15cm more each than the UK king without any extra length, so the bed grows sideways rather than creeping towards the foot of the room.
- Cooler with a crowded bed: The copper-infused memory foam is designed to move heat away faster than standard memory foam, which helps when extra bodies are adding warmth under one duvet.
- Steadier surface for shared nights: A Medium Firm feel should mean a dog or child lying close by creates less of a dip, so you are less likely to roll towards the middle.
This size suits you if...
You share with a partner whose movement regularly wakes you, or your children and a large dog end up in the bed most nights, and 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 opening wardrobe doors would leave you squeezing past the bed. We'd recommend the UK king instead, where we suggest at least 2.7m x 2.9m.

Is a UK super king Fusion Pro big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each, so a small child tucked between you still leaves both of you a usable strip of mattress. If a child shares every night into their later years, the space shrinks quickly, but the UK super king is the largest mainstream size and the one most likely to keep everyone asleep.
Sleepeezee Fusion Pro super king vs king: is the extra width worth it?
It is if you disturb each other. The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each. The trade-off is floor 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.
Will I feel my partner move on a super king Fusion Pro?
Less than on a smaller size. The UK super king gives 22.5cm more each than the UK double, and distance does a lot to reduce disturbance. The 800 pocket springs also move independently, so a partner shifting position shouldn't set your side moving as well, although a very heavy turn may still register slightly.
Will a super king mattress fit in a loft conversion bedroom?
Only if the full-height floor area is large enough. In a loft room the slope of the roof usually decides which wall the headboard goes against, so measure the space where you can stand upright. Allow at least 3m x 2.9m, and check you can still get in and out on both sides without stooping.
Can a large dog sleep on a UK super king Fusion Pro with two people?
A UK super king is the most realistic size for it. With 90cm each for two adults, a dog at the foot or along one edge takes space without pushing anyone off. The Medium Firm feel should help the surface stay level under an animal's weight, though a big dog sprawling across the middle will still cost you room.
