The essentials

Do mattress toppers actually improve sleep?

Yes. A good topper adds pressure relief and comfort to a firm or ageing mattress without the cost of replacing it.

How thick should a mattress topper be?

5–8cm is the sweet spot. Thinner toppers feel negligible, and anything thicker can make your fitted sheet too tight.

How long does a mattress topper last?

3–5 years with regular use. Rotate it every few months to prevent body impressions forming.
