I bought this for my son and it was a great crib that we thought we would be able to use for years but unfortunately it is stuck as a crib. The instructions for the toddler bed states there needs to be a stretcher bar and it makes it seem like it is included but it never was. I tried looking to see if I could purchase one but when I put in the model number on the crib it says it is not a valid model number. So as a crib alone it's good but it should not be called a 4-in-1 if it can not actually be turned into 4 different things.
