The Graco Bailey Toddler Bed is a perfect transition bed for a toddler. The great thing about this bed is that it fits a standard crib mattress. There are guardrails on each side of the bed. The guardrails are also detachable. The mattress fits snugly into the frame so there is not any movement in between the fame and mattress. The bed frame is very sturdy and also easy to put together. You'll want to note that the weight limit is 50 pounds max. I like the design of the bed, it's very simple and timeless - it will go with pretty much anything. I especially like that this is very low to the ground in case of accidental falls, but most importantly so my child can get in and out by herself. I would recommend this bed.
