We only had this sofa for a couple of days.  The back cushions slump down with every seating (see picture).  I can't spend my days pushing and fluffing them back up.  Otherwise it seems solidly built and the bottom cushions are very comfortable and soft (not firm).  I'm thankful I could return it, however, after contacting Customer Service, Wayfair said that this is normal for the cushions so I personally had to pay to ship it back.  This was my first Wayfair experience - disappointed in the product.

Pros: soft/fluffy bottom cushions
Cons: back cushions slump
