Layer Details
Pillow top and knitted cover
A stitched-in pillow top that acts like a built-in topper, under a soft knitted cover. It gives the surface a cushioned feel without a separate topper to slip about.
Memory foam
Thick memory foam that moulds to your body, reacting to natural warmth and pressure. That means it contours around your shoulders and hips.
High-density and soft polyester layers
High-density and soft polyester layers that add support and recovery. They help the mattress spring back after you move.
1200 pocket springs
Individually pocketed springs that target pressure relief and contour to your body. The 1200 count is stated for a UK king, so it may differ in other sizes.

Key benefits
- The most personal space for two: Each sleeper gets 90cm of width on the UK super king, which is 15cm more each than on the UK king.
- Distance from a restless partner: Memory foam moulds to each of you separately, and on a UK super king there is simply more mattress between you when one person turns over at 3am.
- Room for a child or dog to climb in: If a toddler or a large dog joins you most nights, the 6ft width means two adults aren't left clinging to the edges.
- Full length for taller sleepers: At 200cm, or 6ft 6in, the UK super king matches the UK king for length, so you gain width without losing any legroom.
- One continuous pillow top: The stitched-in pillow top runs across the whole surface, so you get a cushioned feel edge to edge without a separate topper shifting about on a mattress this wide.
- Proportion in a large bedroom: In a high-ceilinged period master or a big new build bedroom, a UK super king fills the space properly where a UK king can look a little lost.
This size suits you if...
You share the bed with a partner who tosses and turns, children or a large dog regularly end up in with you overnight, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or your stairs and landing are tight. 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 UK super king Sleepeezee Lasting Memory 1200?
You each get 90cm of width. That is 15cm more each than the UK king version, which gives 75cm each, and 22.5cm more each than the UK double, which gives 67.5cm each. If you currently share a UK double and keep waking each other, the UK super king is a noticeable change.
Does the Sleepeezee Lasting Memory 1200 super king have 1200 springs?
The 1200 figure is given for the UK king, and the count may differ in the UK super king. If the spring count matters to you, ask the retailer before ordering. The feel should otherwise be the same: a medium rating with a pillow top and memory foam that make the surface feel softer.
What size bedroom do I need for a UK super king mattress?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add bedside tables on both sides. In a loft conversion, check where the ceiling slopes first, because a bed 6ft wide usually has only one wall it can sit against comfortably.
Will a super king pillow top mattress fit through my door and up the stairs?
At 180 x 200cm and 24cm deep, it is a large, heavy item to carry. Measure the door swing, any tight landing turns and the stair width before you order, then compare the retailers listed on this page. Budget for new bedding too: you'll need super king sheets and a 260 x 220cm duvet.
Is a super king better than a king if my partner is a restless sleeper?
For most couples, yes. The UK super king is 30cm wider than the UK king and the same length, so the extra space goes entirely on the gap between you. The memory foam helps a little, but distance does more to stop a partner's movement waking you than any comfort layer.
