Layer Details
- Cooler Extreme cover. The mattress is topped with Sleepeezee's Cooler Extreme fabric cover.
- Pillow top. A built-in pillow top cushions the surface for extra body support. It gives that plush, sink-in first impression without needing a separate topper.
- StayCool gel. Pressure-sensitive StayCool gel contours to your body, creating an edge to edge floating feeling. Its thermal control regulates body temperature and reduces heat build-up, which means less of the clamminess softer mattresses can cause.
- Superbond foam. A layer of Superbond foam filling sits beneath the gel, adding cushioning between the comfort layers and the springs.
- Pocket springs and Softech springs. 2,400 pocket springs work alongside Softech springs for total-body support. Because each spring moves independently, you should feel less disturbance from a partner shifting in the night.

- 90cm of your own: Each sleeper gets 90cm, which is 15cm more each than the UK king, so a restless partner's turning happens a little further away from you.
- Distance first, springs second: The extra width does most of the work with a fidgety partner, and the 2,400 independently moving pocket springs absorb much of the movement that still reaches you.
- A share for everyone: When a child wanders in at night or the dog settles by your feet, the full 6ft of width means nobody is left clinging to a sliver at the edge.
- Heat from more bodies: More people in one bed means more warmth, and the StayCool gel's thermal control is designed to reduce that build-up, which helps when the bed regularly holds more than two.
- In proportion in a large room: In a big period bedroom or a generous master, a UK king can look slightly lost, whereas 180cm of width fills the space in proportion.
This size suits you if...
You share with a partner who moves a lot and want real distance between you, or your children or dog regularly join you overnight, and your bedroom comfortably clears the 3m x 2.9m we suggest as a minimum.
Consider another size if...
Your room is under 3m x 2.9m, or you sleep alone and rarely share. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee Cooler Extreme 2400 super king big enough for two adults and a child?
For a child who visits in the night, yes. The UK super king is 180cm wide, the same as two UK singles side by side, so a small child can fit between two adults without anyone near the edge. If it happens every night and the child is growing, it will feel fuller, and this is the widest size this mattress comes in.
Cooler Extreme 2400 king or super king for a restless partner?
The UK super king gives 90cm each, against 75cm each on the UK king, so you gain 15cm of personal space. Both sizes use the same pocket springs, but physical distance does more than any spring system to stop you feeling a partner turn over. Choose the UK super king if your room clears 3m x 2.9m.
Is the Sleepeezee Cooler Extreme 2400 super king worth it over the double?
For two adults, the gap is large. The UK super king is 45cm wider and 10cm longer than the UK double, and gives 22.5cm more each. The UK double suits a smaller room, needing at least 2.6m x 2.8m, but a restless couple will feel the difference every night.
Will a Cooler Extreme 2400 super king fit in a loft conversion bedroom?
Often, but the sloping ceiling usually decides which wall the bed goes on. At 200cm long, the head needs to sit where you can sit up comfortably. Measure the floor area you can stand up in, rather than the whole footprint, and check it against the 3m x 2.9m we suggest as a minimum.
Can a large dog sleep on a Sleepeezee Cooler Extreme super king with two people?
Yes, if you accept the dog will take a chunk of someone's 90cm. The UK super king leaves more room than any other size of this mattress, and the independent pocket springs mean a dog jumping up or resettling is less noticeable. Because the pillow top means it cannot be flipped, a washable protector is sensible.
