In the Sleepeezee Cooler Extreme 1800, a cool-touch Cooler Extreme fabric cover sits over StayCool gel, which reduces heat build-up, so if you regularly wake up too warm this is a sensible shortlist candidate. Beneath that, pocketed and Softech springs provide body-cushioning support, with 1,800 springs in the king size (other sizes may differ). It's 30cm deep and sits at a fair mid-market level for a hybrid with cooling technology. Sleepeezee also holds a Royal Warrant of Appointment granted by HRH The Prince of Wales, a mark of long-standing quality.

Why should you choose this mattress?
Choose this mattress if overheating is your main complaint. The cooling story runs through the whole build: a heat-dispersing cover, then pressure-sensitive StayCool gel that creates an edge to edge floating sensation while keeping temperatures down. The pocket springs respond to each sleeper individually, which means less disturbance when a partner moves. It's hypoallergenic, comes in four UK sizes from Single to Super King, and Furniture Village backs it with a 20-year guarantee, which is longer than most brands offer. The medium firmness suits most sleepers, although anyone who prefers a firm, unyielding surface should look elsewhere. It's a real spend, but the cooling technology and spring system justify it for warm sleepers.
Key features & layer details
Cover
A Cooler Extreme fabric cover with cool-touch properties, which means the surface feels noticeably cooler when you first lie down. It works by dispersing heat away from your body through the night.
StayCool gel
Pressure-sensitive StayCool gel that creates a supportive, edge to edge floating sensation. It also reduces heat build-up, so warm sleepers should feel a genuine difference.
Pocket springs and Softech springs
Pocketed and Softech springs deliver body-cushioning comfort, with 1,800 springs in the king size. Each spring moves independently, which means support that follows your shape rather than pushing back as one unit.
Superbond foam
Superbond foam forms part of the filling system, adding a stable comfort layer beneath the springs and gel.

Best suited for?
Warm sleepers
A cool-touch Cooler Extreme cover sits over StayCool gel, which reduces heat build-up and helps you stay comfortable if you often wake up too warm.
Couples
Pocket springs respond to each sleeper individually, which means you should feel less disturbance when your partner moves during the night.
Allergy sufferers
The mattress is described as hypoallergenic, which makes it a sensible option if you want a sleep surface that suits sensitive sleepers.
Side sleepers
Medium firmness with pressure-sensitive StayCool gel gives a cushioned, floating feel, which lets shoulders and hips settle in comfortably when lying on your side.
If you want a firm mattress for a bad back or you sleep mostly on your front, this medium feel may let your hips sink a little too far. Budget shoppers should also note the starting price; there are cheaper hybrids if cooling isn't a priority for you.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

How firm is the Sleepeezee Cooler Extreme 1800?
It's a medium. That suits most back and side sleepers, although lighter side sleepers may find it slightly firmer than expected, and dedicated front sleepers who need a firm surface may want more resistance.
How many springs does the Sleepeezee Cooler Extreme 1800 have?
The king size contains 1,800 pocketed and Softech springs. Smaller sizes such as the double may have a different count, as spring numbers usually scale with mattress size.
What guarantee comes with the Sleepeezee Cooler Extreme 1800?

It's 30cm deep, a generous depth that means you may need deep fitted sheets. It's available in UK Single, Double, King and Super King sizes.
