Perfect for low beds even on tallest setting wouldnt work for tall bed. I like how it can stay at on a slant to prevent choking. The wheels move pretty well. The rocking feature is a bonus. Nice and breathable all around. Easy to assemble and put away in the storage bag it comes with. The mattress comes with a removable cover which is nice and easy to clean. Easy to adjust height. Can be connected to bed which is nice. I like how one side can be unzipped for easy access while connected to bed.
