Sofa came sooner than promised, delivery person helped me carry big box in house.  My husband and I put it together in 20 minutes.  That included removing from the box.  The sofa material looks very sturdy, and the cushions are firm, all the better to suit me.  The mechanism to go from sofa to bed could not be easier and 2 legs come down from back of sofa for support when sofa is used as bed.  One negative is the legs are made of a plastic, wish it were metal or wood, feel it would be more supportive. The arms just slide over metal tabs on side of sofa, so don't think you are going to hang over the arms.  I just appreciate the look of the arms. Measure the space you have sofa is lower than you may expect.  This is used in kids tv room.  For the price this is way more comfortable than a futon and really doesn't look like futon either.
