Crib Mattresses

Choosing a Crib Mattress

A crib mattress size standard is 51 5/8″ long, 27-1/4″ wide and 5 1/2″ thick. Take careful measurement of your baby’s crib before you start shopping, so that you can find a mattress which will fit snugly inside the crib frame. There should be no more than a fingertip space between the edge of the mattress and the crib frame’s inner surface, to make sure that tiny hands and feet are not in danger of being pinched.
