UPDATE-
I just got these put together at my parents beach house yesterday. They fit the long wall of the room (footboard to footboard) and my girls love them. Most important they fit on the beds and will have about 3 yrs in them. They are narrower than a regular toddler bed or twin, but they are the perfect length at 65". I chose the Kritter in white and they were even easy to setup. Thanks for your help!
What would be te maximum age/size child to fit in a toddler bed? I'm thinking of getting two for my girls to keep in our bedroom at my parents' summer house. They're currently sleeping on a full size inflatable matress and it stinks since it takes up half the room. We can't fit a full size bed since we already have a queen and a pack n play. Is it pointless since they're almost 4 and both are around 41"? Would we get at least 2yrs in these beds?
