A 140 x 70cm mattress fits standard cot beds and lasts from birth until your child moves to a bigger bed. Choose foam or fibre for a lightweight, hypoallergenic sleep surface, or pocket sprung for longer-lasting support. Measure the inside of your cot bed first: the gap should be no more than 4cm on any side.
