I ordered this futon for a spare bedroom after reading several reviews.   I absolutely love it!!  It is very sleek looking, and comfortable to use as a sofa or a queen size bed.  Although I have not slept on it, we have had overnight guests who said it is very comfortable.  I bought a mattress cover for it, along with queen sheets and they fit perfectly.   My husband put it together and it took about an hour.  I would definitely recommend this futon and mattress!!
