Layer Details
Copper Infused Memory Foam
Copper helps reduce heat build-up and dissipates body heat away more quickly, which means you're less likely to wake up overheated than with traditional memory foam. It also offers antimicrobial properties, keeping the sleep surface fresher.
White Fibre Filling
This layer cushions the movement of the springs beneath, so you feel a smoother surface rather than individual coils. It also helps reduce allergens, a plus if you're sensitive to dust.
800 Pocket Springs
Each of the 800 pocket springs adjusts independently, which means the mattress responds to your body shape rather than pushing back as one unit. That translates to targeted support and less motion transfer between partners.

Key benefits
- More room for each of you: At 75cm each for two sharing, the UK king gives you 7.5cm more than a UK double, which means less edging towards the side to avoid a partner's elbows.
- Quieter early starts: The 800 pocket springs move independently, so if one of you gets up hours before the other, less of that movement should reach the person still asleep.
- Length for a taller partner: At 200cm, the UK king is 10cm longer than a UK double, which means a partner over six foot is less likely to have their feet reaching past the end.
- Cooler with two in the bed: Two people build up more heat than one, and the copper-infused memory foam draws warmth away faster, which should help a couple where one of you runs a little warm.
- Plan the room carefully: We suggest at least 2.7m x 2.9m, so measure a new build master bedroom after the fitted wardrobes are in, because built-in units take up floor space quickly.
This size suits you if...
You share the bed every night and a UK double leaves you both short of space, one of you is over six foot and keeps running out of length, or you work different hours and want the early riser to disturb the other a little less.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Fusion Pro Hybrid UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each for two sharing, which is 7.5cm more each than a UK double. If one of you sprawls, or a dog regularly joins you, the UK super king gives 90cm each, so the UK king gives 15cm less each by comparison.
Will I feel my partner moving on the Fusion Pro Hybrid king size?
You should feel less than on a smaller size. The 800 pocket springs respond individually rather than as one unit, and the UK king adds 7.5cm of width each over a UK double, so there is more distance between you. A very light sleeper may still notice a partner getting in or out of bed.
Is the Sleepeezee Fusion Pro Hybrid king long enough for a tall person?
The UK king measures 150 x 200cm, or 5ft x 6ft 6in, which is 10cm longer than a UK double. That extra length is often the main reason a couple with one partner over six foot sizes up. The UK super king is the same length, so moving up again gives you width but no more length.
Should I get the Fusion Pro Hybrid in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king and gives 15cm less each for two sharing. We suggest at least 2.7m x 2.9m for the UK king and at least 3m x 2.9m for the UK super king. If your room only just fits the UK king, it is the more practical choice.
