Question: what is the difference between a crib and toddler mattress?
Answer: In other words, crib mattresses and toddler mattresses are one and the same. The real difference lies in the sheeting and the fact that a crib is enclosed and a toddler bed is not. ... Toddlers, however, can use pillows, blankets and a nice warm comforter. The size of the actual mattress, however, stays the same.
