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
- 90cm each for two sleepers: Each person gets 90cm of width, which is 15cm more each than the UK king, so a restless partner's movements are much easier to sleep through.
- Space when the family piles in: When a small child or the dog climbs in during the night, the UK super king leaves enough width for everyone to lie flat rather than cling to the edge.
- Steadier edges on a wide bed: Three rows of firmer springs run around the border, which means the outer edges feel more stable, useful when a crowded UK super king pushes you towards the side.
- In proportion with a large room: In a period property or a generous master bedroom, the UK super king fills the space comfortably where a UK king can look slightly undersized.
- All the extra space goes into width: The UK super king is the same length as the UK king, so every extra centimetre goes sideways, where sharing sleepers feel it most.
This size suits you if...
You share with a partner who tosses and turns or regularly have children or a large dog join you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or a sloping loft ceiling leaves no full-height wall for the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a Hypnos Henley Pillowtop Supreme super king fit in my bedroom?
We suggest a room of at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling right once you add bedside tables and space to walk round. If your room falls short, the UK king needs at least 2.7m x 2.9m.
How much space does each person get on a UK super king Henley Pillowtop Supreme?
Two people sharing get 90cm each. That's 15cm more each than the UK king and 22.5cm more each than the UK double, which makes a real difference if one of you sprawls or fidgets through the night.
Is a super king big enough for a couple plus a child or a dog?
For occasional visits from a small child or a dog, the UK super king's 180cm width is the most room you'll find in standard UK sizes. The firmer spring border helps the edges stay steady when someone ends up sleeping near the side. If a large dog shares every night, expect a cosier fit.
What bedding do I need for the Hypnos Henley Pillowtop Supreme super king?
Buy super king sheets and a 260 x 220cm duvet. The mattress is 28cm deep with a pillow top, so check that your fitted sheet's pocket depth is generous enough to tuck under comfortably. Super king bedding is a step up in cost from UK king sets, so budget for it.
Will a 6ft mattress get up my stairs and round the landing?
At 6ft x 6ft 6in and 28cm deep, the Henley Pillowtop Supreme in a UK super king is a large single piece to manoeuvre. Measure tight landing turns and check which way the bedroom door swings before ordering. It can't be flipped, so use the border handles when rotating it in place.
