Buying guide
What thickness of mattress topper should I choose?
Thinner toppers (around 2.5-3cm) refresh the feel of a mattress in good condition. Thicker toppers (5-10cm) do more to change firmness or add cushioning to an older, firmer mattress.
Memory foam or fibre or natural materials?
Memory foam contours to your body and suits pressure or joint pain, but can retain heat. Fibre toppers are cheap and machine washable but compress faster. Wool and down are naturally temperature-regulating and long-lasting, but usually cost more and need special care rather than a standard wash.
Can a mattress topper fix an old, sagging mattress?
A topper can improve comfort and add some cushioning, but it will not fix structural sagging or a mattress that has lost its support. If the mattress itself is worn out, a topper is a short-term improvement rather than a long-term fix.
How do I keep a mattress topper clean?
Check the specific product, since washability varies a lot: some are fully machine washable, some have only a removable cover you can wash, and natural down or wool options usually need airing or professional cleaning instead.
