I ordered 3 custom covers from ALCO and just received them. I ordered the 18 oz heavy duty vinyl, and I’m seeing them in action as it’s been raining all day. My patio furniture was nice and dry! I was in contact with customer service to determine if my particular cover was possible (a cover for an umbrella and a round table so that I wouldn’t have to take the umbrella down and could cover it nightly). It was possible, and I’m impressed. There is a small flap that covers the hole where the umbrella goes if I ever do take the umbrella off, plus the covers fit perfectly to correspond the measurements I provided them. The round table cover also has a Velcro split, which is super heavy duty and seems like it would hold in all types of inclement weather. I also ordered a bar cover and it was just as I expected. I chose the clips for the bottoms to withstand heavy snows and winds here in the Midwest, and I like how those tighten and make it even more secure. If I need any additional covers in the future, I’ll definitely be coming back to ALCO to order. In this case, I believe I got what I paid for and these are going to hold up for a really long time and protect my furniture the best.
