I bough two each of the yellow, orange and green ones, and am so happy we're now designing our redecoration around that colour scheme.  
One complaint, the cushion pads are really cheap and the fabric doesn't move freely within the cushion so they become a bit distorted and twisted inside the cover.  I've replaced the pads with new feather filled pads from dunelm.  Not a huge problem, as I bough the cushions based on the covers, but if you're working on a budget you might want to factor this in, or live with having to reshape the cushions every so often (not a big deal, hence the loss of only one star).
