Have had the chairs for almost a week, and we love them!  They were easy to assemble, are firm and very comfortable, and look great in our living area.  We purchased a rug to go with them, and I'm so pleased with how true the colors in the photos of the chairs and the rug were.  They look great together.  I like that the covers have zippers (though I have not tried them) and that the cushions are loose, so that I could change decor if I want.  Despite being unattached, the cushions do not move or slide.
