What a great piece of furniture!  A rather small piece when you first see it, but it can be converted into so many pieces.  You can use it with ottomans, or not.  You can put one ottoman up on the sofa, and make a nice resting place for you to place things while you sit in the other side, which becomes a chair.  It folds out on the floor to make a comfortable full-sized bed.  It is a very firm, dense foam, which is of a high quality compared to similar types of modular furniture in the '80's.  the covering is a rich velvet-type of fabric, which wears well, and seems to repel stains.  We bought it in the  dark red color and it looks great.  It was definitely worth the money.  I love it! 

Pros: styel, durability, comfort
Cons: can't think of any
