The Sleepeezee Cool Response Gel Hybrid comes in a medium firmness, which suits most sleepers, although anyone who prefers a firm, unyielding feel may want to look elsewhere. It's 27cm deep and sits comfortably in the mid-market. It's single-sided, so you'll never need to flip it, just rotate it now and then. Sleepeezee is an NBF-approved manufacturer, and the mattress is hypoallergenic and vegan friendly, which is a little unusual for a hybrid at a mid-range starting price.

Why should you choose this mattress?
If you're a hot sleeper, this is where the Cool Response makes its case. The Cool-Touch cover and StayCool™ Gel layer are designed to keep surface temperature steadier through the night, which means fewer sweaty wake-ups. Beneath that, 1000 individually pocketed springs at medium tension adapt to your movements, so couples should notice less disturbance when one of you shifts. It's backed by a Sleepeezee 10-year guarantee, as listed on the MattressNextDay product page. Yes, the gel layer gives gentle rather than deep cushioning, but that keeps the feel supportive rather than sinky. It comes in sizes from UK Single to Super King, and it's good value for a branded hybrid.
Key features & layer details
Cool-Touch Cover
A soft Cool Touch cover that helps maintain the correct temperature through the night. You'll feel it most on warm evenings, when the surface stays a little cooler against your skin.
StayCool™ Gel
A generous layer of StayCool™ Gel that gently moulds to your body shape, which means personalised cushioning without the enveloping hug of traditional memory foam. The gel is also part of the mattress's temperature-management story.
Pocket Springs
Individually pocketed springs at medium tension provide targeted support, each one adapting independently to your movements. That independence helps limit motion transfer if you share the bed.

Best suited for?
Warm sleepers
The Cool-Touch cover and StayCool™ Gel layer are designed to keep surface temperature steadier, which means fewer sweaty wake-ups on warm nights.
Couples
Individually pocketed springs at medium tension adapt independently to movement, so you should notice less disturbance when your partner shifts or gets up.
Allergy sufferers
The mattress is hypoallergenic, which makes it a sensible pick if you want bedding that suits sensitive sleepers.
Eco-conscious buyers
It is vegan friendly and made by an NBF-approved manufacturer, which is a little unusual for a hybrid at this level.
Budget buyers
The copy calls it good value for a branded hybrid, with three layers, a 27cm depth and a 10-year guarantee included.
This isn't the mattress for you if you want a firm feel: the medium tension will feel a little too giving for some heavier sleepers or dedicated front sleepers. It's single-sided, so if you prefer a flippable mattress for even wear, look elsewhere. If you prefer deep, sink-in memory foam, you may find the gel layer's cushioning too gentle.
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.

FAQ's
How firm is the Sleepeezee Cool Response Gel Hybrid?
It's a medium firmness. That suits most back and side sleepers, offering a balance of cushioning from the StayCool™ Gel layer and support from the pocket springs, although lightweight side sleepers wanting a plush feel, or heavier sleepers wanting firm support, may find it a compromise.
Does the Sleepeezee Cool Response mattress need turning?
No. It's single-sided, so it should never be flipped. Rotating it from head to toe occasionally will help the comfort layers wear evenly.
How many springs does the Sleepeezee Cool Response Gel Hybrid have?
It has 1000 individually pocketed springs at medium tension. Because each spring moves independently, the mattress adapts to your body and limits how much you feel a partner's movements.
Does the Sleepeezee Cool Response Gel Hybrid come with a guarantee?
The MattressNextDay listing states a Sleepeezee 10-year guarantee. Terms can vary between retailers, so check the guarantee details wherever you buy.
Is the Sleepeezee Cool Response good for hot sleepers?
It's built with hot sleepers in mind. The Cool-Touch cover and StayCool™ Gel layer are designed to keep the sleep surface at a steadier temperature, and the sprung construction allows more airflow than an all-foam design.
