I was really leary of buying a futon mattress online.   I carefully read the reviews and felt confident that I was purchasing a quality product as well as getting free delivery.
I couldn't be happier with my purchase!  It's everything I expected.  It's comfortable as a bed as well as a couch.  The firmness is ideal.  I would highly recommend this mattress.

Pros: Comfortable, firm, quality product
Cons: none
