Assessed from Sleep Story's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draws here are temperature control and firm support at a modest price. The Tencel cover wicks moisture away, which means a drier, cooler sleeping surface, and it's a good fit for sensitive skin. The mattress is hypoallergenic too. Open coil springs with reinforced sprung edges support you right to the edge of the bed, handy if you share and end up sleeping near the side. It's non-turn, so no wrestling it over every few months, though rotating it is still sensible. Open coil is a simpler spring system than pocket springs, so couples may notice more movement transfer. But at £349 to £599 with a 20-year guarantee behind it, the value case is strong.
Key Features & what's inside
- Microquilted cover. A quilted cover made with eco-friendly Tencel®, a natural fabric that helps control moisture, so the surface stays drier through the night. It's also a gentle choice if you have sensitive skin.
- Reflex foam. A layer of Reflex foam, a firmer, more responsive alternative to memory foam. You get cushioning without the slow, sinking feel, which suits people who move around in the night.
- Open coil springs. Open coil springs form the support core, with reinforced sprung edges so you can use the full width of the mattress without the sides collapsing. This is what gives the mattress its firm, supportive feel.

Who's it NOT for?
This is a firm mattress, so lightweight sleepers and dedicated side sleepers may find it presses on shoulders and hips rather than cushioning them. Couples who are easily disturbed should also think twice: open coil springs move as one unit, so you'll feel a partner's movements more than you would with pocket springs.

Is the Sleep Story Cool Sleep mattress firm or soft?
Sleep Story describes it as firm. That suits back and front sleepers, and heavier sleepers who need plenty of support, but lighter side sleepers may find it a little too solid at the shoulder and hip.
How long is the guarantee on the Sleep Story Cool Sleep mattress?
It comes with a 20-year guarantee, which is longer than most brands offer. As with any guarantee, keep your proof of purchase and check the terms for what's covered.
Does the Sleep Story Cool Sleep mattress need turning?
No, it's a non-turn design, so you never need to flip it. Rotating it head to toe now and then is still a good habit, as it helps the comfort layers wear evenly.
Is the Sleep Story Cool Sleep mattress good for hot sleepers?
It's designed with hot sleepers in mind. The cover uses Tencel®, a natural fabric that helps control moisture, and the sprung core allows air to move through the mattress, so it should feel cooler than an all-foam design.
How much does the Sleep Story Cool Sleep mattress cost?
Prices range from £349 to £599 depending on size, starting at £349. Six UK sizes are available, from small single through to super king. Delivery is quoted within 14 days, with a premium delivery service at £39 for mattresses.
