I like that the cover comes off. The mattress is very soft it’s not extremely tall so we put it on top of my daughters mattress. I think it would be fine for a younger child or a starter mattress. I’ll sign on using this when my toddler graduates to a twin bed. The top is very soft and doesn’t mess with my child’s sensory issues. overall I’d say this is a great mattress. ￼￼￼￼
