The is very comfortable. I got the queen 10in and i love it so soft and seat pretty high. I didn’t need a box spring i just got a bed frame. I recommend it if your looking for a bed when your on a budget. I just moved into my first apartment and it was pretty cheap compared to getting a mattress from somewhere in store and i say best decision i ever made. It definitely a good choice!! My only down side is my room is pretty small so it takes up most of it but i knew that was gonna happen when i decided i went a queen bed lol.
