I have two, one sofa in the living room and one sectional in the family room.
I like the look for the price. I think they are comfortable and have held up well, but the best quality and looking sofa we have is from Room and Board. It might be more expensive, but I would buy from there if you are concerned about quality.
FWIW, we also have one west elm bed and one room and board bed (both upholstered). The west elm bed has been great for 10 years, and the r and b for the past 5.
