I bought this to use every night and I like it. 

Normally I don't have any back problems. However, sometimes I sleep for long periods (like 9+ hours). Regular mattresses and foam mattresses can leave me with a backache after long sleeps. Firmer surfaces don't give me this problem. This 10" thick futon feels like the best of both worlds, it's comfortable but also firm. 

Also, like foam mattresses and UNlike regular mattresses, it doesn't transfer movement, so if one person is moving around it doesn't move the whole bed. God for sex too. Well, there isn't any bounce...but being able to hold position (like with a foam mattress) can be nice.

Wayfair: Shipped quickly. Box was heavy but compact enough to move without much trouble. Mattress expanded quickly and didn't off-gas that I could tell.
