A convertible crib is a crib designed to change form as your child grows. A 4-in-1 convertible crib, for example, converts from a standard crib into a toddler bed, a daybed, and eventually a full-size bed, often using conversion kits. It’s a popular choice because one piece of furniture can last from infancy into the school-age years.

A standard, full-size crib fits a standard crib mattress and offers the most room for a growing baby, making it the right choice for most nurseries. A mini crib is smaller and more portable, which makes it ideal for compact bedrooms, apartments, or a second sleep space at a grandparent’s home. Mini cribs use a smaller mattress, so be sure to pair each crib with its matching mattress size.

Most children use a crib from birth until around age two to three, when they’re ready to move to a toddler or big-kid bed. A convertible crib extends that timeline considerably: because it converts to a toddler bed, daybed, and full-size bed, the same frame can carry your child well into their school years.

A full-size crib uses a standard crib mattress, which should fit snugly inside the frame with no gaps at the sides for safety. Mini cribs use a smaller, mini-crib mattress. Crib mattresses are usually sold separately, so check the crib’s specifications and choose a mattress made for that crib size.
