However, there can be a difference of an inch or two depending on the different manufacturers. Though this mattress is small, it is very comfortable, firm, and soft.
What Is a Standard Crib Mattress Size?

The best part? If the child grows, he can still use the same mattress for a certain age. Due to the standard sizing, the accessories for such mattresses are also easier to find in the market.
