I am looking at purchasing the Bradington Young Warner sectional. The problem is, I have never sat in it. Just wondering if anyone has. Does it have good back support? I am not a big fan of the couches with seats so deep, that by the time you get your back up against the cushions, your feet can't touch the floor. Is is a sink-in kinda couch or sit on top of the cushions couch? Thank you!
