Layer Details
Damask Cover
A breathable Belgian damask fabric cover. It lets air move through the sleep surface, which helps if you run warm at night.
Comfort Fillings
A blend of British wool and silk. Both are natural fibres that wick moisture, so the surface feels comfortable without trapping heat.
Support Layer
A layer of Ecobond that supports your spine and relieves pressure whatever position you sleep in. This is where the extra firm character of the mattress comes from.
Comfort Fillings
Polyester and cotton layers with good rebound and recovery, which means the mattress springs back to shape rather than developing body impressions quickly.
Support System
1,600 barrel-shaped pocket springs, each mounted in its own fabric pocket and working independently. You get support that follows your body's shape, and less motion transfer from a restless partner.

Key benefits
- 90cm each for two: With 90cm per sleeper you can lie fully stretched out, which means a partner who turns over all night is simply further away from you.
- 15cm more each than a UK king: Compared with the UK king, each of you gains 15cm of width at the same length, a clear difference if your elbows currently meet in the middle.
- Independent springs across a wide surface: The 1,600 pocket springs move separately, so on a bed this wide a heavier partner rolling over barely registers on your side.
- Room for a child or a large dog: When a child climbs in during the small hours or the dog settles at the foot, the extra width means the adults still keep a usable share.
- In proportion with a big bedroom: In a period property or spacious master bedroom, a 6ft x 6ft 6in bed sits in proportion where a smaller size can look a little lost.
This size suits you if...
You share the bed every night with a partner who tosses and turns, you want a properly firm surface without giving up any width, or children and pets regularly join you and your room comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or turning a large double-sided mattress sounds like too much work. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Ortho Bespoke Silver 1600 super king good for couples of different weights?
Yes, and the UK super king helps more than smaller sizes. Each of you gets 90cm, and the independent pocket springs respond to each body separately, so a heavier partner doesn't tip you towards the middle. Keep the extra firm rating in mind, though: a lighter partner, especially a side sleeper, may find it too unyielding.
Should I buy the Sleepeezee Ortho Bespoke Silver 1600 in a super king or a king?
The UK super king is 30cm wider than the UK king at the same length, giving 15cm more each for two sharing. Choose the super king if you have the room and a restless partner. If your room is nearer our suggested 2.7m x 2.9m for the UK king, the smaller size leaves you space to move around.
How hard is it to turn a super king Ortho Bespoke Silver 1600?
It is a two person job. The fillings are double-sided, so turning is part of owning it, and at 180 x 200cm and 26cm deep the UK super king is the most awkward size of this mattress to handle. Sleepeezee doesn't publish a weight, so plan for a helper and clear floor space before you start.
Is a super king extra firm mattress suitable for sharing with kids or a dog?
On space, yes: the width lets a child or a large dog fit in without pushing the adults to the edges. On feel, children are light and won't sink into an extra firm surface much, so this suits occasional visits better than a bed chosen around a child's comfort.
Will a super king Ortho Bespoke Silver 1600 fit in a loft conversion?
Check floor space first: we suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. In a loft conversion the sloping ceiling usually decides which wall the headboard goes against. Leave headroom on one side for lifting and turning the mattress too, which a low slope can make awkward.
