Layer Details
Cotton and viscose cover
An unbleached cotton and viscose ticking that is naturally flame-retardant without added chemicals. If you want a chemical-free cover, this is a reassuring starting point.
Solotex
A soft Solotex layer sits at the top and the base. It adds a gentle cushioning layer to the surface, and because the mattress turns, you get it on both sides.
British wool
Layers of British wool from Red Tractor assured farms. Wool is a natural fibre, so it gives you a traditional, natural-fibre feel.
Cotton
Two layers of responsibly sourced cotton. They add to the natural filling and help build up the comfort layer above the springs.
eOlus fibre layer
The final layer around the ReActive 8-turn pocket spring core is made from adaptive eOlus, a recycled fibre. It sits between the fillings and the springs, so you get a recycled material in the build.

Key benefits
- Room for two proper sleepers: At 75cm each for two people sharing, you both get genuine personal space rather than negotiating the middle of the bed.
- 15cm wider than the UK double: The UK king is 15cm wider than the UK double, a difference you notice on the first night you stop bumping elbows.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK double, so anyone approaching six foot keeps their feet on the mattress.
- Kinder on different schedules: If one of you gets up hours before the other, the extra width means an early alarm is less likely to wake the whole bed.
- A sensible fit for most master bedrooms: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms can manage without giving up wardrobe space.
This size suits you if...
You share the bed every night and a double has started to feel tight, especially if one of you is a restless sleeper or you keep different hours. It also makes sense if either partner is on the taller side, since the 200cm length is the quiet upgrade here, or if a dog has become a permanent fixture and keeps claiming more than its share.
Consider another size if...
Your bedroom falls below our suggested 2.7m x 2.9m minimum, or you sleep alone and don't need the width. We'd recommend the UK double instead, which needs a slightly smaller room at 2.6m x 2.8m.

FAQ's
Is the Hypnos Orthos Support 8 UK king big enough for a couple?
Yes, comfortably for most. At 150 x 200cm you get 75cm each for two people sharing, which is enough to change position without disturbing your partner. If you regularly share with a child or a large dog, the UK super king is 30cm wider and may be the better call.
What room size do I need for the Hypnos Orthos Support 8 in a UK king?
We suggest at least 2.7m x 2.9m, which leaves room to walk round the bed and open drawers. In a new build master bedroom, measure after accounting for wardrobes: rooms that look generous empty can feel tight once furniture is in. If yours falls short, the UK double needs at least 2.6m x 2.8m.
How does the UK king compare with the UK super king for this mattress?
The UK king is 30cm narrower than the UK super king, and the two are the same length, so sizing up buys width only. Both sizes of the Orthos Support 8 are listed on this site, so compare the retailers shown on each page. We suggest at least 3m x 2.9m for the UK super king.
Is the UK king worth it for a tall sleeper?
Often, yes. The UK king is 10cm longer than the UK double as well as 15cm wider, and for anyone over six foot that extra length is usually the upgrade that matters. Hanging your feet off the end of a 190cm mattress every night gets old quickly; 200cm solves it.
Where can I buy the Hypnos Orthos Support 8 in a UK king?
Availability for this size is shown in the live price table on this page, and the prices there are updated as retailers change them. This model has limited stockist coverage, so there's less scope to shop around than with more widely stocked mattresses. It pays to check back if the listing changes.
