I bought this outdoor patio chair cover in Apr '20 to replace a different cover (from Classic Covers) that lasted less than 3 years. The Vailge product, when compared to what it is replacing, appears to offer superior material, with equivalent detailing and features. Both have snap clip bands to secure the cover around a chair leg as well as an elastic drawstring with toggle closure to adjust tension. Both feature sewn seams (rather than fused) and corded seams are taped over the sewn seam. Both have vents to inhibit interior condensation and being alofted by the wind. The Classic Covers are 100% woven polyester with a laminated PVC backing. These are 100% 600 denier oxford cloth, which is also polyester, but seems more durable. This material is also used for window awnings or baby strollers and offers superior waterproofing. It has been UV stabilized, but as I just purchased these, can not yet comment on how well they will hold up in the sun. Happy to return after a few months to confirm UV resistance.
