How to Choose

  • Side sleepers: Softer mattress (memory foam or soft pocket sprung) for shoulder and hip pressure relief.
  • Back sleepers: Medium-firm for spinal alignment. Pocket sprung or hybrid.
  • Front sleepers: Firm mattress to prevent lower back sag. Firm pocket sprung.
  • Couples: Pocket sprung (1000+ springs) to minimise partner disturbance. Hybrid is also excellent.

When to Buy a Mattress

Mattress prices follow predictable patterns:

  • Cheapest: Bank holiday weekends (May, August), Black Friday, Boxing Day
  • January: Good deals as retailers clear stock
  • Avoid: March-April and September-October when prices are typically highest

Tips for Saving on Mattresses

  1. Compare across retailers — The same mattress can vary by £50-£200 between stores.
  2. Consider lesser-known brands — Many use the same factories as premium brands at lower prices.
  3. Check trial periods — Many online mattress brands offer 100-night trials. Use them.
  4. Negotiate — In-store retailers often match online prices if you ask.
  5. Buy the mattress, skip the base — A quality mattress on a basic frame outperforms a cheap mattress on a fancy base.

Frequently Asked Questions

How often should you replace a mattress?

Every 7-10 years for most mattresses. If you wake up with aches or notice visible sagging, it's time regardless of age.

Is an expensive mattress worth it?

Up to a point. Our data shows that quality improves significantly between £100 and £500 mattresses, but the difference between £500 and £1500 is marginal for most sleepers. A £300-£600 mattress hits the sweet spot of quality and value.
