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
- More room each: At 75cm each for two sharing, you get 7.5cm more space per person than on a UK double, which means fewer knees and elbows meeting in the night.
- Length for taller sleepers: At 200cm (6ft 6in), the UK king is 10cm longer than a UK double, so a taller partner can lie straight rather than angling across the bed.
- Easier on split schedules: If one of you gets up hours before the other, the extra width gives a little more distance to slip out quietly without clambering over a sleeping partner.
- The full spring count: Sleepeezee states the 1200 pocket spring count for the UK king, with each spring individually pocketed so it contours to the shape of whoever is lying on it.
- A sensible step up: You get a real gain over a UK double without needing the 3m x 2.9m floor space we suggest for a UK super king.
This size suits you if...
You share the bed every night and keep ending up on top of each other on a UK double, one of you is over six foot and wants room to lie out straight, or you need space to build a wall of pillows during pregnancy on a cushioned surface.
Consider another size if...
Your bedroom measures less than our suggested 2.7m x 2.9m once the wardrobes are in. The UK double would suit you better, and we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the Sleepeezee Lasting Memory 1200 Pillow Top UK king big enough for two people?
For most couples, yes. The UK king measures 150 x 200cm, giving 75cm each when two of you share, which is 7.5cm more each than a UK double. If you both sprawl or a dog joins you most nights, the UK super king gives 90cm each, though we suggest at least 3m x 2.9m of floor space for it.
Does the UK king Sleepeezee Lasting Memory 1200 actually have 1200 springs?
Yes. Sleepeezee states the 1200 pocket spring count for the UK king specifically. Other sizes of the same mattress may have a different number of springs, so if the exact count matters to you, check the brand's own guidance for any other size you're weighing up.
Is the Sleepeezee Lasting Memory 1200 Pillow Top king size long enough for a tall person?
It's a good choice if one of you is over six foot. The UK king is 200cm long (6ft 6in), which is 10cm longer than a UK double. For a tall partner, that extra length is often a bigger relief than the added width.
What size bedroom do I need for a UK king Sleepeezee Lasting Memory 1200?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving you comfortable space to walk round. New build master bedrooms can feel tighter than expected once fitted wardrobes go in, so measure the room as it will be furnished, then compare the retailers listed on this page.
What bedding fits a Sleepeezee Lasting Memory 1200 king size?
Standard UK king sheets and a 230 x 220cm king duvet will fit. The mattress is 24cm deep, so pick fitted sheets made for that depth or more to stop the corners pinging off when one of you turns over.
