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. Prices run from £429 to £749 across sizes from UK Single to Super King, which is honest value for a branded hybrid.
Key Features & what's inside
- 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.

Who's it NOT for?
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. Fans of deep, sink-in memory foam may find the gel layer's cushioning too gentle.
Sleepeezee Cool Response Gel Hybrid Mattress
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.
