Purchased this to convert the Davinci Emily 4-in-1 toddler bed for my second child.  Combined with the Regency 10" Ventilated Memory Foam Mattress and a box spring, you'll be good to go.  Very sturdy and supports a full size bed well.  Getting ready to purchase another version of the kit for the next kid's bed once he grows out of his 4-in-1 crib.
