The Dream On Me 4-in-1 lifestyle sleigh crib is designed to make it convenient and easy to remove your baby from the crib. Its stationary sides and static side rails remain in place so you never have to raise and lift to lower the rail. This crib has a 3 position mattress support system and converts easily to a toddler, day and full size bed allowing this lovely piece of furniture to grow with your child. It is a great investment made of solid hardwood and has a non toxic cherry finish. This does not included the mattress. It requires assembly.
