Layer Details
Damask Cover
A breathable cover made from Belgian damask fabric. Breathability here means air can move through the surface, which helps the mattress feel less stuffy on warm nights.
Polyester and Wool Blend
A comfort layer blending polyester with wool, which is naturally temperature regulating. In practice that means it helps even out warmth rather than trapping heat against you.
Soft White Fibres
Fibre fillings made from 100% polyester, chosen for recovery and durability. They spring back into shape after use, which helps the surface resist dips over time.
1000 Pocket Springs
Up to 1000 springs, each pocketed so it works completely independently of the others. This gives targeted support and reduces the ripple you feel when a partner moves.

Key benefits
- Real distance from a restless partner: With 90cm each, the independently pocketed springs and the extra width both reduce disturbance, which means a fidgety partner is felt less on your side of the bed.
- Room for late night visitors: When a small child or the dog climbs in, the firm surface stays level under the extra weight, so nobody ends up rolling into a dip in the middle.
- 15cm more each than the UK king: Compared with the UK king, the UK super king gives 15cm more each for two sharing, a difference you notice most when you both sleep on your backs.
- Firm support across the full 6ft: At 6ft x 6ft 6in, the firm feel runs edge to edge, which suits back and front sleepers who want to be held up wherever they settle.
- Extra length over smaller sizes: The UK super king is 10cm longer than the UK double, which helps taller sleepers whose feet hang off a 190cm mattress.
This size suits you if...
You share with a partner whose tossing and turning wakes you, and you want firm support without giving up any width. It also suits you if children or a large dog regularly end up in the bed and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much space does each person get on the Sleepeezee Ortho Firm 1000 super king?
Each of you gets 90cm of width when two people share the UK super king. That is 15cm more each than the UK king and 22.5cm more each than the UK double, which is the extra elbow room that makes a real difference if one of you sprawls.
Sleepeezee Ortho Firm 1000 super king or king: which should I choose?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. Choose the UK super king if a restless partner or children in the bed is the problem. If your room is tighter, the UK king needs at least 2.7m x 2.9m against 3m x 2.9m for the UK super king.
Will I feel my partner move on a super king Ortho Firm 1000?
Less than on a smaller size. The pocketed springs each move on their own, which limits the ripple when someone turns over, and 90cm each puts more physical distance between you. On a genuinely restless partner, that distance tends to help more than any comfort layer could.
Is a firm super king mattress good for sharing with kids and dogs?
Yes, in most cases. A firm pocket spring surface resists sagging where extra bodies pile in, and the UK super king's 180cm width gives everyone a share. The one flaw: lightweight side sleepers may find the firm feel a little hard on the shoulder, so consider who sleeps on the edge.
Where should a super king go in a loft conversion bedroom?
At 180 x 200cm, the UK super king needs a wall with full headroom behind it, so the sloping ceiling usually decides the layout. Allow at least 3m x 2.9m of floor, check the stair turns and door swing before ordering, and keep space to get out of bed without stooping.
