Rem-Fit 600 Lux Black Edition Mattress

Assessed from Rem-Fit's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.

The open-cell memory foam is designed to be breathable, which means you should get the contouring, cradled feel of memory foam with less of the heat build-up it's known for. If you're a hot sleeper who has ruled out foam before, that's worth a second look. Underneath, 4000 pocket springs across a dual-layer system respond to your body individually, so a heavier hip or shoulder gets support without dragging the rest of the surface down with it. It also helps limit motion transfer, useful if you share a bed with a restless partner. The 7.5/10 med-firm tension suits back and front sleepers well, and the price is fair for a hybrid of this depth.

Back sleepers
The med-firm 7.5/10 tension keeps the spine supported on a surface that sits on the firmer side of medium, so you feel held rather than sunk.

Front sleepers
Firmer support from the 4000 pocket springs helps stop the midsection dipping too far, while the memory foam on top keeps the surface comfortable.

Warm sleepers
Open-cell memory foam lets air move through more freely, which means you get the contouring feel of foam with less trapped heat overnight.

Couples
Each pocket spring moves independently, which means movement transfers less across the bed when one of you is restless.

Heavier sleepers
A dual-layer system of 4000 pocket springs responds to your body individually, so a heavier hip or shoulder gets support without dragging the whole surface down.

At a 7.5/10 med-firm tension, this is firmer than a true medium, so lightweight side sleepers may find it a little too unyielding at the shoulder and hip. And if you dislike the slow, hugging feel of memory foam altogether, even a breathable open-cell version, a latex or all-spring design may suit you better.

How firm is the Rem-Fit 600 Lux Black Edition mattress?

Rem-Fit describes it as a med-firm tension, rated 7.5/10. That places it on the firmer side of medium, which suits most back and front sleepers, although lightweight side sleepers may find it slightly too firm.

Is the Rem-Fit 600 Lux Black Edition good for hot sleepers?

It should cope better than traditional memory foam. The top layer uses open-cell memory foam, a structure that lets air move through the foam, and the pocket spring layers beneath allow further airflow. That said, memory foam still sleeps warmer than some alternatives.

How many springs does the Rem-Fit 600 Lux Black Edition have?

It has 4000 contouring pocket springs arranged in a dual-layer spring system. Pocket springs move independently of one another, which means more tailored support and less disturbance when a partner moves.

What sizes does the Rem-Fit 600 Lux Black Edition come in?

Five UK sizes: Single, Small Double, Double, King and Super King.

How long does Rem-Fit 600 Lux Black Edition delivery take?

Rem-Fit quotes delivery within 5-10 working days on its own site. If you buy through a retailer instead, check their delivery terms, as timings can differ.
