This is a fantastic little crib. Granted, it will have a limited lifespan for my 20.5" 6 month old. But, at present, he still fits with plenty of room to spare and I'm confident this crib will last through his first year. I initially purchased this crib for it's size and design. I prefer contemporary lines and natural wood. However, I didn't realize the portability of the crib would also come in handy. We were able to drag it from bedroom to bedroom as we moved the baby into our bedroom and then out again. We use the crib with the Da Vinci 50 coil mini crib mattress (I threw out the thin mattress pad the crib comes with).
