Assessed from Tuft & Springs's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're a hot sleeper who still wants that gentle memory foam hug, this is where the Radiance 1000 makes its case. The gel-infused foam draws heat away from the sleep surface, so you get the contouring without waking up clammy. Underneath, 1000 individually responsive pocket springs move independently, which means less roll-together if you share a bed with a restless partner. The medium firmness works for most back and side sleepers. Prices run from £399 to £799 depending on size, with UK Single through to UK Super King available, and delivery is free next day to mainland UK, though some addresses may incur a small fee. Yes, the 5-year guarantee is a little modest, but at this price it's a fair trade.
Key Features & what's inside
- Sleep Surface. A soft knitted cover gives a breathable, inviting finish. It's the first thing you'll feel, and it helps air move through the top of the mattress.
- Comfort Layer. Cooling Gel Fusion™ memory foam gently contours to your body, which means pressure relief at the shoulders and hips. The gel-infused design draws heat away from the sleep surface to help regulate your temperature through the night.
- Support System. 1000 individually responsive pocket springs move independently to support your body. That independence helps eliminate roll-together, so you're less likely to drift into the middle of the bed.

Who's it NOT for?
If you like a firm, planted feel underneath you, this medium hybrid will likely feel slightly too giving, particularly for heavier back sleepers. And if a long guarantee matters to you, the 5-year cover here is shorter than some brands provide. Small Double isn't listed among the available sizes either.

Is the Tuft & Springs Radiance 1000 good for hot sleepers?
It's designed with hot sleepers in mind. The Cooling Gel Fusion™ memory foam draws heat away from the sleep surface, and the knitted cover adds breathability, so it should run cooler than a traditional all-foam memory mattress.
How firm is the Radiance 1000 Gel Hybrid?
It's a medium, which suits most back and side sleepers. Lighter sleepers should sink in comfortably, although if you prefer a firmer, more supportive surface, a medium-firm option elsewhere may serve you better.
How deep is the Tuft & Springs Radiance 1000 mattress?
It's 29cm deep, which is a substantial depth for a hybrid at this price. Standard fitted sheets should still work, but check deeper-depth bedding if yours run snug.
What guarantee comes with the Radiance 1000?
Tuft & Springs offer a 5-year guarantee. That's shorter than some brands provide, but it's from an NBF-approved manufacturer, and the starting price of £399.00 softens the trade-off.
What sizes does the Radiance 1000 come in?
It's available in UK Single, UK Double, UK King and UK Super King, priced from £399 to £799 depending on size. There's no Small Double listed, which is a shame for smaller rooms.
