Layer Details
Damask Cover
A breathable Belgian damask fabric cover. It lets air move through the surface, which means less heat building up around you overnight.
Comfort Layer
A generous polyester and cotton blend layer that cushions your body. It softens the surface slightly without compromising the firm feel underneath.
Soft White Fibres
Fibre fillings made from 100% polyester. These recover their shape well, which means the comfort layers should resist flattening over time.
Cotton
A natural filling that helps regulate body temperature. It also adds a touch of extra support and comfort.
Pocket Springs
Up to 1600 pocket springs that work independently, contouring to your body as you move. That means targeted pressure relief where you need it, and less disturbance from a partner shifting about.
High-density Support Layers
Dense support layers on both sides of this double-sided mattress. They add further pressure relief and let you flip the mattress to spread the wear.

Key benefits
- 90cm each for two: With 90cm each for two people sharing, you get 15cm more per person than the UK king, which means a turning shoulder rarely crosses onto your partner's side.
- Movement stays local: Up to 1600 independently moving pocket springs spread across 180cm of width, which means a partner getting up early is far less likely to jolt you awake.
- Space for small visitors: When a child pads in after a bad dream or the dog claims a corner, 180cm of width still leaves both adults a usable share of the bed.
- Wider without being longer than the UK king: The UK super king matches the UK king's 200cm length, so moving up from the UK king adds width without changing where the foot of the bed sits.
- Double-sided, with a heavier flip: Yes, turning a mattress this size is a two-person job, but flipping it spreads wear across both sides of a bed that two adults use every night.
This size suits you if...
You share with a restless partner and want the most distance a mainstream UK bed offers on a firm surface, children or a large dog regularly end up in the bed with you, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your room falls short of 3m x 2.9m, or you'll be flipping the mattress on your own. The UK king would suit you better; we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the Sleepeezee Ortho Firm 1600 super king worth it over the king?
If your partner tosses and turns, usually yes. The UK super king is 30cm wider than the UK king at the same length, giving 15cm more each. An extra firm mattress has little give to soak up a partner's movement, so extra distance does more of the work. If your room is tighter, we suggest at least 2.7m x 2.9m for the UK king.
Can one person flip a super king Ortho Firm 1600?
Realistically, it's a job for two. The mattress is double-sided and needs regular flipping, and at 180 x 200cm the width alone makes it awkward to handle solo. Sleepeezee doesn't publish a weight for this mattress, so if lifting is a concern, plan for help each time or consider a smaller size.
Is a super king Sleepeezee Ortho Firm 1600 big enough for two adults and a child?
For occasional night-time visits, yes. At 180cm wide there's room for a small child to settle between you without either adult being pushed to the edge. If it becomes a nightly arrangement with older children, even a UK super king starts to feel full, so be realistic about how often it happens in your house.
Is the Ortho Firm 1600 in super king good if your dog sleeps on the bed?
It's a sensible size for it. 180cm of width gives a dog room at the side or foot while both of you keep a proper share, and the independent pocket springs limit how far a dog jumping on or off moves your side. Flip it regularly so the dog's favourite spot doesn't wear one area unevenly.
Sleepeezee Ortho Firm 1600 super king vs double for a couple?
The UK super king is 45cm wider and 10cm longer than the UK double, and gives 22.5cm more each. For two adults on an extra firm bed, that gap makes a real difference to how much of each other's movement you notice. The UK double does suit smaller rooms, where we suggest at least 2.6m x 2.8m.
