Good to know
A 10cm mattress topper is one of our deepest options, offering a significant boost in plushness. It's best suited to firmer mattresses that could use extra softness rather than mattresses already on the softer side.
Frequently asked

Is a 10cm topper too deep for my mattress?

It's best suited to firmer mattresses that could use significant extra softness — it may feel excessive on an already soft mattress.

Do I need extra-long straps for a 10cm topper?

Check the individual product, as deeper toppers sometimes require longer securing straps.
