Assessed from Rem-Fit's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main reason to choose this mattress is its firmness. A 9/10 orthopaedic tension suits people who feel unsupported on softer beds, particularly heavier sleepers and those who sleep on their back or front. The 4000 pocket springs are multi-zoned, which means firmer support under your hips where weight concentrates, and they're encapsulated at the edges, so you can sit or sleep near the side without a rolling-off feeling. The memory foam on top is designed to minimise sink rather than cocoon you, keeping your spine aligned instead of letting hips and shoulders drop. Free 2-5 day delivery, a 100-night trial and a 15-year guarantee round out a genuinely low-risk purchase.
Key Features & what's inside
- Memory foam. A stability-focused memory foam layer that minimises sink, which means you'll feel cushioned rather than swallowed. It's designed to stop your hips and shoulders dropping out of alignment.
- Pocket springs. 4000 dual-layer orthopaedic pocket springs with multi-zoned support, so different areas of your body get the right level of push-back. Encapsulated edge support keeps the perimeter usable for sitting and sleeping.

Who's it NOT for?
At 9/10 firmness, this is not a mattress for lightweight side sleepers, who will likely find it too hard on the shoulders and hips. If you prefer a plush, sink-in feel, look at softer hybrids instead. The stability-focused foam here is deliberately restrained rather than cuddly.
Rem-Fit 4000 Ortho Elite Hybrid Mattress
How firm is the Rem-Fit 4000 Ortho Elite Hybrid?
Rem-Fit rates it as a firm orthopaedic tension, 9/10 on their scale. That places it firmly at the harder end of the market, best suited to back and front sleepers or anyone who finds softer mattresses leave them unsupported.
Does the Rem-Fit 4000 Ortho Elite come with a trial?
Yes. Rem-Fit offers a 100-night trial, so you can sleep on it at home for over three months before committing. It also carries a 15-year guarantee, which is longer than most brands offer.
How many springs does the Rem-Fit 4000 Ortho Elite have?
It contains 4000 dual-layer orthopaedic pocket springs. These are multi-zoned, meaning the support varies across the mattress to match how your body weight is distributed, and the edges are encapsulated for a sturdier perimeter.
How much does the Rem-Fit 4000 Ortho Elite Hybrid cost?
Prices range from £449 to £720 depending on size, starting at £449.99. Sizes run from UK Small Single up to Super King, with EU Single, Double and King sizes also available. Delivery is free and takes 2 to 5 days.
How deep is the Rem-Fit 4000 Ortho Elite mattress?
It's 25cm deep, which means standard fitted sheets should fit without a struggle, and it's substantial enough to feel like a proper hybrid rather than a thin foam mattress.
