Size guide

Measure the inside of your bed frame, width and length, then find the matching size. Go by the frame, not your old mattress, as mattresses flatten and spread over the years.

Bunk beds, high sleepers and cabin beds have a maximum mattress depth. Check it on the bed's page and choose a mattress that's the same depth or less.

Some shorty beds take a 70 x 160 cm mattress rather than 75 x 175 cm, so check your bed's mattress size before you order.
