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.
