FAQs

550GSM or 1000GSM - which should I choose?

Choose 550GSM for gentle cushioning and 1000GSM for a deeper, plusher feel.

Will it fit under my fitted sheet?

Usually, but check your mattress depth plus topper height against the fitted-sheet pocket.

Will a topper fix an old mattress?

It can improve surface comfort, but it cannot restore lost support underneath.
