The corner slots / flaps don't stay on the existing canapy frame; constantly slipping off. We added an extra strap of Velcro on each corner to hold the corner slots. Also if we don't have the frame tilted, when it rains the rain pools in the middle & drips through to the seat. We never had this problem with the original canapy. To solve this problem, we just leave it tilted when we're not using the swing & have the seat cushion inside, so it doesn't get wet.  I was going to return it but this is the cheapest replacement swing canapy I could find & the color matches perfectly. So I just altered it a bit to make it work.
