Layer Details
Pillow top
Generous layers of cotton and Solotex recycled fibres sit on the surface. They give gentle full-body cushioning, so the medium-firm feel is softened where you lie.
6-Turn pocket spring unit
Hypnos' ReActivePro 6-Turn pocket springs form the support layer. They give the mattress its medium-firm base, so your body is held up while the pillow top cushions it.

Key benefits
- Room for a restless partner: With 90cm each, a partner who turns over all night has space to move before you feel it, and the gap does more for disturbance than any comfort layer can.
- 15cm more each than a UK king: The UK super king is 30cm wider than the UK king at the same length, which means a noticeably roomier bed without needing a longer room.
- Usable right to the edges: Triple Edge Protection and hand side-stitching help the edges keep their shape, which means a child or dog squeezed in at the side still has a supportive surface to lie on.
- Pillow top across 6ft of width: The cotton and Solotex pillow top runs across the full 6ft x 6ft 6in surface, so everyone gets the same gentle cushioning over firm spring support.
- Suits a grand bedroom: In a high-ceilinged period bedroom or a generous master, a 30cm deep pillow top at this width looks in proportion where a UK king can seem a little lost.
This size suits you if...
You share the bed with someone who fidgets, kicks or gets up at odd hours, or a child or large dog joins you most nights and you'd rather not be pushed to the edge. A bedroom of at least 3m x 2.9m, with room for the door to open past the bed, helps too.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m or you 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 a Hypnos Stellar Superior Pillowtop super king?
Two people sharing get 90cm each on the UK super king. That is the same width as a UK single per person, so each of you has a full sleeping space of your own. If a restless partner wakes you, that distance tends to help more than any change in softness or firmness.
Is the UK super king worth it over the UK king for this mattress?
It depends mostly on your room and your sleep partner. The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each for two sharing. If you are regularly disturbed or share with children or pets, that extra width helps. If space is tight, the UK king needs at least 2.7m x 2.9m.
What size bedroom do I need for a UK super king pillowtop mattress?
We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling more comfortable once bedside tables and wardrobe doors are in play. In a loft conversion, check where the ceiling slopes first, as the slope usually decides which wall the bed can go against.
Can kids and a dog share a super king Hypnos Stellar comfortably?
A UK super king is the size most families pick when small visitors arrive in the night. The medium-firm springs support adults properly, and the reinforced edges help whoever ends up at the side feel secure. With two adults, a child and a large dog, expect it to feel full, but far less cramped than a UK king.
What bedding fits a UK super king Hypnos Stellar Superior Pillowtop?
You'll need super king sheets and a 260 x 220cm duvet. Because the mattress is about 30cm deep with a pillow top, look for fitted sheets with deep pockets so the corners stay put. Super king bedding costs more than smaller sizes, so factor that into the total spend.
