If you sleep hot, this is where the Cool Refresh earns attention. The sleeping surface is cool to the touch, and beneath it sits Staycool gel that responds to your body shape while helping regulate temperature, which means less of that clammy, wake-at-3am feeling. The white fibre filling cushions spring movement and reduces allergens, useful if dust sensitivity bothers you. Support comes from a pocket spring core, and the extra firm feel suits sleepers who want a properly solid base. It's non-turn, so no wrestling the mattress over twice a year, and the 10-year guarantee gives reasonable long-term reassurance at this price.
Key Features & what's inside
- Cool-Touch Surface. A sleeping surface that feels cool to the touch, designed to reduce body temperature. You'll notice it most when first getting into bed.
- Staycool™ Gel. Pressure sensitive gel that responds immediately to your body shape, which means contouring without losing the firm feel. It also helps regulate body temperature through the night.
- White fibre filling. This layer cushions spring movement and reduces allergens. A sensible inclusion if you're prone to allergies.
- Pocket spring core. The spring system at the heart of the mattress, providing the underlying support.

Who's it NOT for?
Sleepeezee describes the feel as extra firm, so lightweight sleepers and dedicated side sleepers may find it too unyielding at the shoulder and hip. If you prefer a plush, cradling surface, look elsewhere. It's non-turn, which suits most people, but rotation is still your only maintenance option.

Is the Sleepeezee Cool Refresh 1600 firm or extra firm?
Sleepeezee's own product page describes the feel as extra firm, although some retailer listings label it firm. Either way, expect a solid, supportive surface with very little sink, best suited to those who like sleeping on rather than in their mattress.
Does the Sleepeezee Cool Refresh 1600 need turning?
No. It's a non-turn mattress, so you never flip it over. Rotating it end to end now and then is still a good habit to even out wear.
How deep is the Sleepeezee Cool Refresh 1600?
It's 24cm deep, and that depth is consistent across all sizes, from UK Single up to Super King. Standard fitted sheets should fit without trouble.
What guarantee comes with the Sleepeezee Cool Refresh 1600?
Sleepeezee backs it with a 10-year guarantee, which gives you solid long-term cover for a mattress in this price bracket.
Is the Sleepeezee Cool Refresh 1600 good for hot sleepers?
That's its main pitch. The cool-touch surface reduces body temperature at contact, and the Staycool gel layer underneath helps regulate temperature through the night. If overheating is your main complaint, the design is squarely aimed at you.
