Layer Details
Knitted Cover
A soft knitted cover that's breathable, which means heat can escape rather than build up around you. It helps keep you at an even temperature through the night.
Memory Foam
This layer adds a soft, cushioning feel, gently moulding to your shape as you settle in. It takes the edge off the firm support underneath.
Pocket Springs
Individually pocketed springs move independently from one another, so the mattress responds to your body's movements more effectively. In practice, that means support where you need it and less disturbance from a restless partner.

Key benefits
- 90cm each for two: Sharing a UK super king gives each of you 90cm of width, which means a partner who turns over all night is far easier to sleep through.
- 15cm more each than a king: Compared with the UK king, you each gain 15cm of width at the same 200cm length, so the extra room goes sideways where restless couples need it.
- Springs that keep movement local: The pocket springs flex independently, and across a bed this wide that means a shift on one side is unlikely to travel to the other.
- Space for small visitors: When a child wanders in at 3am or the dog claims the foot of the bed, a UK super king still leaves both adults a usable share of mattress.
- Firm support across the full width: The firm pocket spring base gives even support edge to edge, which helps a larger household share the bed without anyone sinking towards the middle.
This size suits you if...
You share the bed with someone who tosses and turns, and space helps more than any comfort layer could. It also fits when children or a large dog join you most nights, 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 you sleep alone. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

FAQ's
Is the Spring King Pocket Memory Ortho 1500 super king good for a restless partner?
It's a strong pairing. The UK super king gives each of you 90cm of width, against 75cm each on the UK king, and the pocket springs move independently so movement stays largely on one side. Distance does most of the work here. The firm feel also means less wobble as someone rolls over.
UK super king or UK king for the Spring King Pocket Memory Ortho 1500?
The UK super king is 30cm wider than the UK king and the same length, giving each sleeper 15cm more. The trade-off is floor space: we suggest at least 3m x 2.9m for the UK super king and at least 2.7m x 2.9m for the UK king. If your room clears the larger figure, the extra width is useful.
Is a UK super king big enough for two adults and a child?
For the occasional night visitor, yes. With 180cm of width, a small child can settle between you without either adult ending up on the edge. The firm pocket spring support also helps, because nobody rolls towards a dip in the middle. If a child sleeps in with you every night, expect things to feel busier.
Will a super king mattress work in a loft conversion bedroom?
It can, but the sloping ceiling usually dictates where the bed goes. Place the headboard against the tallest wall so you can sit up without hitting your head, then check you still have walking room on each side. Measure the usable floor with full head height, rather than the total footprint, against our suggested 3m x 2.9m.
Does a UK super king suit a large period property bedroom?
Often, yes. In a generous room with high ceilings, a smaller bed can look lost, and the UK super king's 180cm width fills the space more convincingly. Before ordering, check door swing, landing turns and staircase width, since older houses can have tight corners. For the room to feel right, we suggest around 3.5m x 3.2m.
