The Sunbrella fabric is beautiful with a subtle bi-color weave and a lovely natural yellow green (I bought the Kiwi color). The bottom cover zips off, the seat and back cushions are separate so reversible. I wanted to love them! However the seat cushion was not very firm, it wasn't really 5" as described, the welt actually measures 4" and then it poofs up a bit from the poly fill, so maybe that's where the 5" is coming from. When we tried it, the seat cushion sunk to where you could feel the chair bottom and I weigh 120lbs. I think these might work better for rattan chairs or any chair where the seat frame is one supportive piece. We have metal chairs where the seat frame is crossed straps and the cushion did not hold its shape enough. For our chairs we need something firmer. The covers are so nice, I even considered buying new seat cushions to go inside, as I think one of the other reviewers mentioned doing.
