I was a bit apprehensive to order a mattress online and carefully read all reviews on the several options under consideration. In the end, we went with this mattress and it did not disappoint. I was nervous about the quality due to the price as so many others were far more expensive. We bought the queen, it is very heavy! It went on the futon no problem and it is incredibly comfortable. The mattress is very good quality and well made. It looks great on our new futon. Overall, completely satisfied with our purchase!  Given the weight of the queen size mattress, expect to need 2 people to navigate the futon from bed to couch position. Converting from couch to bed wasn’t an issue.
