4 stars for design and durability. It’ll survive any climate and keep ur patio furniture perfect. Tiny deduction for the ties that lash it to ur chair legs/crossbars being way too short. I knotted mine out of frustration and cold—here’s hoping they untie in spring.Now the bad. Chock full of bad chemicals—fails California P65 law. There’s phthalates and lead in it(made in China FYI). You can really really smell the chemicals. I tried airing them in my basement before putting them on the chairs(so the heat indoors would soften them after their frozen trip here), but the smell is too much to keep them indoors very long. I put them on the chairs and washed my hands right away. It says on the package that the chemicals are harmful to pregnant women and children. I don’t take this lightly bc the smell of chemicals is very very strong, so I’m assuming heavy concentrations of chemicals in the material.To their credit, these covers are well made, very sturdy and fit a range of chair sizes. My complaint really is I was expecting heavy canvas with a kind of backing material, and these seem heavily chemically treated inside and out. So I do have concerns about children and pregnant women handling them…and I would wonder how much will seep into the wood grain of my chairs. The point was to protect my newly refinished furniture, not make more work resealing them to keep these toxins in.I think if you’re aware of exactly what ur buying and are ok with it, these are great. But if ur thinking more natural canvas, it’s def not that or natural. Good luck disposing of them in a landfill when they’re past their useful life.Overall, good design just overly complicated with toxic chemicals. If I could sew, I would have just sewn some covers outta heavy canvas. Live and learn I guess.
