Mattress came much faster than expected. I've never done a bed in a box and was a little concerned about how it would turn out. Well, the experience so far was great! This mattress came well packed and immediately expanded to full size when opened. I didn't notice any corners with issues and was very happy with the outcome. 

The mattress itself is very comfortable. Firm, but with enough give to make a side sleeper happy. I would definitely recommend this mattress!
