If you sleep warm but still want a cushioned, pillow-top feel, this is the balance the Cooler Extreme 2400 aims for. The pressure-sensitive StayCool gel contours to your body while its thermal control regulates temperature, so you get the hug of a soft top layer without quite so much of the heat that usually comes with it. Underneath, 2,400 pocket springs paired with Softech springs give whole-body support, which means less roll-together for couples. Furniture Village lists a 20-year guarantee, a long span of cover, though as with most guarantees the fine print will matter. Sizes run from UK Single to Super King.
Key Features & what's inside
- 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.

Who's it NOT for?
The medium feel suits most sleepers, although heavier stomach sleepers who need firm spinal support may find it a little too forgiving. Pillow tops cannot be flipped, so anyone who prefers a turnable mattress should look elsewhere. And at £899 upwards, budget shoppers will find simpler hybrids for less.

Is the Sleepeezee Cooler Extreme 2400 good for hot sleepers?
It is designed with hot sleepers in mind. The StayCool gel layer uses thermal control to regulate body temperature and reduce heat build-up, and the pocket-sprung core allows more airflow than an all-foam mattress. No mattress is a cure for serious overheating, but cooling is this model's main focus.
How firm is the Sleepeezee Cooler Extreme 2400?
It has a medium feel, softened further by the built-in pillow top. That combination suits side sleepers and lighter back sleepers well, though those who want a properly firm surface should consider something else.
What guarantee comes with the Sleepeezee Cooler Extreme 2400?
Furniture Village, which lists this mattress exclusively, states a 20-year guarantee. That is a long span of cover, though it is the retailer's stated term, so check the conditions with them directly before buying.
How many springs does the Cooler Extreme 2400 have?
It contains 2,400 pocket springs, working alongside Sleepeezee's Softech springs. Each pocket spring moves independently, which means better contouring to your shape and less motion transfer between partners.
How deep is the Sleepeezee Cooler Extreme 2400?
It is 32cm deep, which counts as a deep mattress. Standard fitted sheets may struggle to stretch over it, so look for extra-deep bedding, and bear in mind it will sit noticeably tall on a high bed frame.
