I bought this to use at my house when my granddaughter is here.  What a disaster.  The bottom will not lock into place no matter what we do.  The mattress is dinky and the metal bars can be felt.  I don't want to sit or sleep on metal bars and I sure don't want my grandbaby to either.  This was the worst purchase ever.  I bought this because of the Evenflo name.  Huge mistake!!
