Layer Details
Base pocket springs
The interior starts with a base layer of pocket springs. This gives the mattress its underlying support, so the layers above have a stable foundation.
Tablet pocket springs
A layer of tablet pocket springs sits on top of the base layer, each one wrapped in its own cloth sleeve. Because each spring works on its own, the surface can follow your shape rather than moving as one piece.

Key benefits
- 90cm each for two: Two people sharing get 90cm each, which is 15cm more per person than the UK king and enough distance that a restless partner becomes far easier to sleep through.
- Space when a child wanders in: When a little one climbs in during the night, the 6ft width means everyone can still lie flat rather than two adults clinging to opposite edges.
- Individually sleeved springs across a wide surface: The tablet pocket springs each sit in their own sleeve, so on a bed this wide, movement on one side tends to stay on that side.
- In proportion with a large room: In a period property or a generous master bedroom, the UK super king's 180cm width looks right, where a UK king can seem slightly lost against the wall.
- Bedding with real overhang: Super king sheets fit, and a 260 x 220cm duvet hangs well over both sides, so neither of you wakes up tugging the covers back.
This size suits you if...
You share with a partner whose movement keeps waking you, children or a large dog join you overnight as a matter of routine, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or a sloping loft ceiling leaves no wall long enough. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Will a Silentnight Geltex Mirapocket 2000 Pillowtop super king fit my bedroom?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. Check that the bedroom door and wardrobe doors can still swing open once the bed is in. In a loft conversion, the slope usually decides which wall the bed goes against, so measure the full-height section, not the floor.
Is a super king big enough for two adults and a child?
For two adults alone, the UK super king gives 90cm each, which is the most room of any standard UK size. A child in the middle will eat into that, of course. Even so, the extra width over a UK king gives everyone a little more room, which is the main reason families sharing a bed choose it.
How much bigger is a super king than a king mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length. For two people sharing, that works out at 15cm more each. The UK king needs a smaller room too: we suggest at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king.
What size duvet fits a super king Geltex Mirapocket 2000 Pillowtop?
Use super king fitted sheets and a 260 x 220cm duvet. Bedding at this size costs more than for a UK king, and the choice of designs in shops can be slightly narrower, so it's sensible to factor in a full new set of sheets and covers when you budget.
Will a super king mattress get up the stairs and round the landing?
Silentnight doesn't publish a depth or weight for this mattress, so check the retailer's listing before ordering. With 180cm of width to carry, the tight spots are usually landing turns and narrow doorways. Measure each one, and compare the retailers listed on this page for their full specification.
