Cot mattresses in 120 x 60 cm

Most cots sold in the UK are built around a 120 x 60 cm mattress, so if you have a standard cot, or our Clara Mini Cot Bed, this is the size you need. Our cot mattresses are hypoallergenic, made in Great Britain, and finished in our signature bamboo fabric. They are naturally antimicrobial and softer than cotton, with a removable cover that washes at 40°C and a waterproof side for those first potty training days.

Before you order, measure the inside of the cot frame: a cot mattress should fit snugly, with no gap of more than 3 cm. If your cot bed is full size, you need a 140 x 70 cm cot bed mattress instead.
