Owned the white SupraRoos for 5+ years before replacing. Didn't want the white, so the sales staffer suggested these (KoverRoosIII), assuring me that they would be equally protective from rain water. We bought the replacement set in June 2019. They fit great, BUT 7 of the 9 covers purchased leak like a sieve!!! These are used from May-October, then stored indoors. We have a deck trunk for summer storage when dry and not in use -- we take care of them!). During a rainstorm, you can see the fabric growing darker in place where it is letting water in. It's not the seams, condensation or water left to pool. We go out after storms to shake any leaves or water off, only to find cushions, tables and wicker furniture wet!!! Beyond disappointed. We spent close to $600 for these and they are mostly worthless. Either upgrade to a the SupraRoos or buy your covers from a more reliable source!!!
