I think the quality of the product is great. I was surprised that a bed in a box still was able to have springs. I also was worried with it being 8” it would be a little too small but it's actually perfect for a bed frame or something of the sort, especially if you put a topper on it.

Comfortable Bed!

The mattress takes about 2 weeks for the smell to leave. It is not too bad of an odor, but I didn't want to smell that all night. I aired out the mattress, using fans and Febreeze. The bed is super comfortable and fits into the bed that I bought on Amazon. Good find!
