My husband purchased this sofa for his art room. It is definitely for a studio or college student, not for your main sofa. It sets low to the floor and is 'ok' comfortable.  The arms can be switched to make it a left hand or right hand chaise. However, the end of our sofa's slide in metal plate for sliding in the arm is crooked. Hence, we have not been able to put on of the arms on.  It will require drilling very carefully in order to avoid jeopardizing the hole that is already in place which holds the metal plate onto the sofa. 
As I said, the sofa is for a studio, but I would look further if I had this selection to do again. 

Pros: studio worthy 
Cons: metal plate for sliding in arm is crooked - hence arm will not go on
