Sealy Posturepedic Elevate Bentham Mattress

Assessed from mattress data provided by our UK retail partners, captured October 2026, and from regular price comparison across those retailers.

The main reason to pick this mattress is its soft feel. If you've found firmer mattresses hard on your shoulders and hips, a soft rating is the place to start, because the surface gives way rather than holding you up. That tends to suit side sleepers and lighter sleepers best, as they put less weight through the mattress and are more likely to enjoy that cushioned feel. It's also sold in four sizes, from a UK single up to a UK super king, so it can work for one sleeper or two. The downside is that a soft mattress won't suit everyone, particularly if you sleep heavier or on your front.

Side sleepers
The soft rating means the surface gives way rather than holding you up, so shoulders and hips can sink in a little for a cushioned feel.

Lighter sleepers
Lighter people put less weight through the mattress, so the soft surface is more likely to feel gently cushioned rather than too yielding.

Couples
Sizes run from a UK single up to a UK super king, including a UK double and UK king, so there is a fit for two sleepers sharing.

If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated soft, so the surface is built to give rather than push back. Heavier sleepers, and back or front sleepers who want a flatter, more supportive feel, may find it too yielding. Sealy doesn't publish a depth either.
