These covers are durable and 100% waterproof. They cover my oversized gliders perfectly!Just received the large wicker chair cover. Looks to be well made and waterproof. We'll find out tonight as rain is expected.As I have a wicker glider/rocker w/ round tubular metal base, I was really interested in the drawstring feature for a quick cover up for those spring and summer showers that pop up. (I had just bought a cover from Amazon, which is nice, and has 4 straps that clip on the bottom. But I have to get on my knees and just raise the base ever so slightly to get the straps anchored. At 68 years and 240 lbs., it was no fun).So I was disappointed to find that there is no drawstring as advertised in the description or in the video, which is why I bought this cover. Looked all over the box, and there is no mention of a drawstring, at least for this particular wicker chair cover.Now it's a matter of do I get on all fours to attach the clip/buckle from one cover or use the Velcro with this cover. Very disappointing. But as I said previously, the HD vinyl should hold up to the elements.Heavy duty material and I liked the straps at the bottom only we were not able to use the straps as our chairs were too short to take advantage of them. We ended up trying rope around the base of the chair to keep the cover attached to the chair as we live in Iowa and it gets windy in the winter and we wanted the covers to cover up the chairs on our wicker furniture that we leave outside in the winter in the snow. This is the first winter we will be leaving the wicker furniture outside in the winter to handle the snow and ice as we normally bring them inside each winter. We wanted something thick and heavy to protect the furniture from the Iowa elements and these are thick and heavy. We have had three snows so far and with the rope wrapped around the bottom we have had no problems with the covers. Time will tell come spring.While these chair covers work well, after 3 years, they have cracked and torn. I bought 4 of these to cover my oversized wicker patio chairs and 2 for my ottomans. After 2 years, the ottoman covers cracked and I had to replace them. THe chair covers, for some reason, lasted 1 year more (total of 3 years), before cracking and tearing. We are very easy on our furniture. We don't use them in the summer and early fall. So they are really only cover our outside patio furniture for about 6 months. No one sits on them, nor if there is water that on occassion pools up, I sweep it off. To my disappointment, they have been cracking and tearing this past winter. I am replacing these as we speak, but trying another brand.Also, even on the 1st year of use, these have mold/mildew on them so I have to clean them with mildew remover after each season. I don't mind this as much as I was hoping these would have last longer than barely 3 years.Weight of the cover is well, and appreciate the inner sewn liner as I feel it helps when one person removing from the resin wicker set we are covering. I see these being a 4-5 season set, sitting in indirect sunlight in afternoon, on our covered patio. We bought the larger sofa cover, two "large wicker chair covers" and two of the ottoman covers. These fit our Agio made, Sams Club branded set of Toronto 6 piece patio set, model 582077 as if it was made for them, which is a nice benefit. Covers are large enough wehreby I can still sit in chairs while covers are still on, such as after yard work where you dont want to soil the chair but you need a break, or the dog doesnt tear it when jumping on your chair. I would buy again for the amount paid. Made in Mexico, which is a nice alternative to all the Made in ROC. Least were buying from our neighbors......The material is not what I expected. It has a thin rubber texture that is unusual. I am skeptical of their durability. I did not return because I needed a cover immediately.This cover the best. It's not cheap looking and does the job. Will purchase more in the future.Purchased these for the first time about 5 years ago. This year, it started to split and dry out. For the price, I cannot complain. It definitely does the job of protecting my stack of 4 chairs. Would recommend.Very pleased with ottoman cover, fits perfectly and quality is great!
