Pillow top with easyflex Gel foam
A pillow top that encases a 3cm layer of breathable easyflex Gel memory foam, along with polyester fibre. It gives the surface a plush, cushioned feel and some contouring.
Dense polyester fibre layer
A 3cm layer of dense polyester fibres. It adds cushioned comfort, so the surface feels softer without losing the support beneath.
Mirapocket pocket springs
1000 Mirapocket springs, each in its own fabric pocket. They form a base of reactive support that responds as you move.

Key benefits
- 90cm each for two: With 90cm each, the width of a whole UK single per person, a partner who turns all night stays well out of your half.
- Space for a small visitor: When a child or the dog climbs in, the 180cm width means both adults keep a usable share rather than clinging to the edges.
- Sides that keep their shape: A reinforced rod edge border helps the sides hold firm, which matters on a wide bed where each sleeper tends to lie nearer their own edge.
- Support that follows each sleeper: The 1000 Mirapocket springs each sit in their own fabric pocket, which means the support responds to where each of you lies across the surface.
- In proportion in a large room: In a period property or a generous master bedroom where a UK king can look a little lost, the 6ft x 6ft 6in footprint fills the space properly.
This size suits you if...
Your partner shifts and turns all night and you want real distance between you, children or pets regularly end up in the bed with 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 tight staircase could stop a flat-delivered mattress. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a UK super king Silentnight Easyflex Gel pillow top fit up my stairs?
It arrives flat rather than rolled, so a 180cm-wide, 31cm-deep mattress has to bend round landing turns and through door frames. Measure the narrowest point on the route, including the way each door swings, then compare the retailers listed on this page. A pillow top has some give, but don't rely on it to squeeze through a tight turn.
How much bedroom space does a UK super king mattress need?
We suggest at least 3m x 2.9m, which leaves room to walk round the bed and open drawers. In a loft conversion, the sloping ceiling usually decides which wall the bed goes against, so check you can sit up and get out on both sides without catching your head.
Is the UK super king worth it over the UK king in this mattress?
The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each when two of you share. That extra matters most with a restless partner or regular visitors in the night. If neither applies and your room is smaller, the UK king needs at least 2.7m x 2.9m.
Can two adults and a child share a super king pillow top mattress?
Yes, on an occasional basis. At 180cm wide, a small child in the middle still leaves each adult a reasonable strip, and the pocket springs respond to each person separately. A larger child every night will feel more cramped, but far less so than on a UK king or UK double.
What sheets and duvet fit a UK super king Silentnight Easyflex Gel?
Super king fitted sheets and a 260 x 220cm duvet fit. At 31cm deep, look for fitted sheets with deep pockets so the corners stay put. Bedding at this size costs more, so factor that in. The mattress is single-sided, so rotate it rather than flip it, which is easier with two people at this width.
