Tutti Bambini CoZee Castors - 4-Pack

I was nervous the stoppers wouldn't hold, but they lock firmly in place once you push them down. The wheels roll smoothly even on our carpet, making it easy to rock the baby from room to room.

These castors click in so easily and the stopper gives me peace of mind when the crib is parked. Makes moving the crib from room to room a breeze, and they feel sturdy enough to handle daily use.

They do make moving the crib around much easier, and the stoppers are a nice touch for safety. I did find that one of the wheels doesn't roll quite as smoothly as the others, though. Works fine for the price, but not perfect.
