I couldn’t be more thrilled with this sofa! I already owned the other matching pieces, purchased from another vendor (my mistake; WAYFAIR offered better value). This piece, from WAYFAIR, was extremely well packaged and included a rubber mallet - thanks! It’s fairly easy to snap together. The existing seat cushions are firm and supportive. I prefer the seat back as is, no added padding necessary. Yes, it’s molded plastic, but it has give to it like actual rattan. It’s been drenched in the rain and baked in the sun, with no ill effects. Strong and secure, it supports the larger members of our household comfortably...affordably making our patio a comfortable added living space. Just be careful not to pound too hard during assembly, so as not shred or crack the plastic.
