Layer Details
Pillow top
A soft pillow top with cosy cotton fibres and Solotex recycled synthetic filling. It gives the mattress its cushioned surface, which means a gentler feel under your shoulders and hips.
Cotton comfort layer
A layer of responsibly sourced cotton that's naturally breathable and cooling. It helps heat escape, so the soft top shouldn't feel stuffy.
Pocket springs
1200 ReActivePro 6-turn pocket springs, each encased in its own cloth pocket, with three rows of firmer springs around the border. The springs support your body, and the firmer border gives steadier edges.
Base
A firm eOlus fibre base made from recycled plastic. It gives the springs a solid foundation and keeps the mattress's recycled content in the build.

Key benefits
- More personal space: At 75cm each, you get 7.5cm more width than on a UK double, which means fewer elbows and knees meeting when either of you turns over.
- Fewer early wake-ups: Each spring sits in its own cloth pocket, and the wider UK king adds distance between you, so one partner leaving hours earlier should disturb the other a little less.
- Length for taller sleepers: The UK king is 200cm long, 10cm more than a UK double, which gives a partner of 6ft or more room to stretch without their feet pressing against the footboard.
- Edges you can sleep on: Three rows of firmer springs around the border keep the outer edge steady, so the full 150cm width feels usable rather than nudging you both towards the middle.
- Soft feel for side-sleeping couples: The medium soft pillow top cushions shoulders and hips well, although on a shared UK king a heavier partner may find their side a little too soft.
- Sensible room footprint: We suggest a bedroom of at least 2.7m x 2.9m, with 3.2m x 3.2m comfortable, so measure a new build master bedroom after the wardrobes go in.
This size suits you if...
You share the bed every night and keep bumping into each other on a UK double, one of you is 6ft or taller and wants the extra length, or you keep different hours and would like a little more distance when one of you gets up early.
Consider another size if...
Your bedroom measures less than 2.7m x 2.9m once the furniture is in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Hypnos Henley Pillowtop Supreme UK king big enough for two adults?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more than a UK double. If you both sprawl or a dog joins you most nights, the UK super king offers 90cm each, but we suggest at least 3m x 2.9m of floor space for it.
Will a tall person fit on a king size Hypnos Henley Pillowtop Supreme?
The UK king is 200cm long, 10cm longer than the UK double and UK small double. That extra length is often the main reason couples with a partner of 6ft or more size up. The UK super king is the same length, so going bigger adds width only.
What size bedroom do I need for a UK king Hypnos Henley Pillowtop Supreme?
We suggest allowing at least 2.7m x 2.9m, and 3.2m x 3.2m if you want comfortable space to walk round both sides and open wardrobe doors. Measure after your furniture is in place, since fitted wardrobes in newer homes can take more floor than you expect.
What bedding fits a Hypnos Henley Pillowtop Supreme king size mattress?
Standard king sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet gives both of you enough to tuck in. The mattress is 28cm deep with a pillow top, so choose a fitted sheet with deep enough pockets to grip the corners securely.
Should I get the Hypnos Henley Pillowtop Supreme in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king and the same length, giving you 15cm less each. If your room is under 3m x 2.9m, the UK king is the practical choice. If you have the floor space and disturb each other often, the UK super king adds real separation.
