UK TOPPER SIZES IN CM

A topper that is too small won't cover your mattress properly and one that's too big can move around as you sleep and be rather uncomfortable.

TOP TIP FOR CHOOSING THE CORRECT SIZE TOPPER

Before purchasing a mattress topper, measure the dimensions of your mattress rather than measuring your bed frame, to ensure you get a proper fit. 

 

SHOULD A MATTRESS TOPPER BE BIGGER THAN MY MATTRESS?

No, a topper that is too big can move around and be uncomfortable. You don't want your topper to be wriggling around beneath you as you try to sleep!

 

SHOULD A MATTRESS TOPPER BE SMALLER THAN MY MATTRESS?

Ideally, a mattress topper should the same size as your mattress. If your topper is too small for your mattress, you risk damaging the topper by stretching it.
