We bought this bed for my son when he was 20 months old and I was pregnant with child #2. He loves it! He loves anything with wheels so we had no trouble moving him from the crib in the nursery to his big boy room complete with car bed (and truck wallpaper border of course!). What I like most about the bed is that the sides are higher than the mattress so that he can't roll out and we don't need a railing. If you feel that you need more of a side I have even seen people take out the box springs so that the mattress is enclosed on all sides. And of course, just like the rest of Little Tikes products, it is very durable. Well worth the money!
