I found their website to be really helpful, not only listing the dimensions of every single futon mattress, but listing all the ""ingredients"" they used to make them as well! I wanted a futon for daily usage as bed, so getting quality ingredients inside my futon was very important to me, and The Futon Shop didn't disappoint. By the time I went down to my local store I knew exactly the kind of mattress I wanted to purchase, and was able to drive it home from their San Francisco location that very day.
Pros: informative website, organic materials, super comfortable
Cons: kind of in a bad neighborhood, I guess
