9 Best Mattresses in the UK (2026)
Updated for 2026 · Prices checked in £ · UK standard sizes.
In short: most UK sleepers do best on a medium-firm mattress — memory foam for couples (no movement transfer), pocket sprung for hot sleepers, hybrid for the best of both. Budget £250–£600 for a quality double, replace every 7–8 years, and always match the mattress size to your bed frame exactly.
Mattress marketing is some of the most confusing in all of furniture: "orthopaedic", "gel-infused", "7-zone" — half of it means very little. What actually matters is simpler: the right firmness for how you sleep, decent materials that don't sag in two years, and the correct UK size. We cut through the jargon to pick nine mattresses that deliver genuinely good sleep at honest prices.
How we pick: materials and construction, firmness accuracy, durability reports from long-term buyers, sleep-trial terms and guarantees. Affiliate links may earn us a commission at no cost to you.

9 · Best Mid-Budget Memory Foam Mattress
Amazon UK
Doubleslee 20cm Gel Memory Foam Mattress — Small Double
£119.95
A step up from bargain-basement foam: 4 cm of gel-infused memory foam over high-density support foam, in a medium firmness that suits most sleeping positions. The gel layer and breathable cover help it sleep cooler than standard memory foam, and the removable cover is washable.
| Build | 20 cm deep; 4 cm gel memory foam + 16 cm support foam |
|---|
| Feel | Medium firmness |
|---|
| Cover | Removable, washable; breathable hypoallergenic fabric |
|---|
Pros
- Gel-infused top layer for cooler sleep
- Removable washable cover
- Solid value in the £100–£130 bracket
Cons
- Unknown long-term durability vs branded rivals
- Basic warranty typical of marketplace brands
- May not suit very light side sleepers
Quick buying tips
- Match your sleep position. Side sleepers need medium/medium-soft for shoulder and hip relief; back sleepers need medium-firm; front sleepers need firm.
- Use the sleep trial. Your body needs 3–4 weeks to adjust. A 100-night trial is only useful if you actually commit to the adjustment period.
- Protect it from day one. A £30 waterproof protector guards a £500 mattress — and most guarantees are voided by stains.
- Check the base. Foam mattresses need solid or closely-spaced slats (gaps under 7 cm); sprung mattresses are more forgiving.
- Measure your stairs. A king-size mattress doesn't bend around tight Victorian staircases — consider a mattress-in-a-box.
Mattress FAQs
What type of mattress is best for back pain?
A medium-firm mattress usually suits back pain best — firm enough to support the spine's natural curve, with enough give at the shoulders and hips. Orthopaedic (extra-firm) mattresses help some back sleepers but can cause pressure points for side sleepers.
Memory foam or pocket sprung — which is better?
Memory foam moulds to your body and isolates movement (good for couples) but can sleep warm. Pocket sprung mattresses breathe better and feel more traditional, with each spring responding independently. Hybrids combine both. Hot sleepers should lean sprung or hybrid.
How often should you replace a mattress in the UK?
Every 7–8 years is the standard guidance. Replace sooner if you wake with aches, the mattress visibly sags, or you sleep better in other beds. A mattress protector can add a year or two of life.
What mattress size do I need for a UK double bed?
A UK double mattress is 135 × 190 cm; a king is 150 × 200 cm; a single is 90 × 190 cm. Buy the mattress in exactly the same size as your bed frame — a 2 cm gap each side is normal, more than that means the wrong size.
Do mattresses in a box work as well as traditional ones?
Yes — vacuum-packed mattresses expand to full size within 24–72 hours and perform like traditional ones. They're far easier to get upstairs in UK homes with narrow staircases. Unwrap within a few weeks of delivery for best expansion.
