What actually matters
- 1Type: foam, spring or hybrid. Memory foam hugs and isolates movement (good for couples, light sleepers); pocket-spring feels bouncier and cooler; hybrid combines both and suits most people.
- 2Firmness to your sleep position. Side sleepers usually want medium/medium-soft for shoulder and hip relief; back/front sleepers tend to prefer medium-firm to firm support.
- 3The trial period is crucial. You can't judge a mattress in a showroom. A 100-night-plus home trial with free returns matters more than any spec — always check it.
- 4Cooling and weight. Foam can sleep warm — look for breathable/gel layers if you run hot. Heavy mattresses are harder to rotate; check if it's one- or two-sided.
Typical UK price bands (2026)
| Budget | What you get |
|---|---|
| £200–£400 | Bed-in-a-box foam and basic spring (double/king) — good value, often with trials. |
| £450–£800 | The sweet spot: quality hybrids with better support, cooling and longevity. |
| £900+ | Premium hybrids and natural-fill mattresses — for specific needs and longest life. |
Common mistakes to avoid
- ✕Buying without checking the home-trial and return terms.
- ✕Choosing 'firm' because it sounds supportive when you're a side sleeper.
- ✕Paying full RRP — mattresses are almost always discounted; the 'sale' is often the real price.

FAQ
Foam, spring or hybrid?
Hybrid suits most. Foam for motion isolation and a hugging feel; spring for a cooler, bouncier feel.
How firm should it be?
Side sleepers: medium/medium-soft. Back/front sleepers: medium-firm to firm. Body weight shifts this too.
Why does the trial period matter?
You genuinely can't tell in a shop — a long home trial with free returns is the real safety net.
