The Cover Store carries a complete assortment of patio table covers and patio table and chair set covers. This cover is designed to be used on an outdoor table without chairs and does not have a hole for an umbrella. If you need other patio table covers that have a hole in the middle, please see our Patio Table Cover overview page. We also have covers that are oval and rectangular in shape, so you should be able to find a patio table cover that fits your outdoor table! This outside table cover is round, but it will cover both square and round tables. It"s made of durable yet lightweight polyester, so it is easy to put on and take off. There are no straps or ties that need to be fastened. Instead, our outside table covers use an elastic bottom with a built-in drawcord to keep the cover snug and secure. Built-in mesh vents provide necessary air circulation around the cover to prevent mold and mildew. As with all of our patio furniture covers from our Elite collection, this round patio table cover is constructed using double stitching on all the seams. We even pay attention to the details on the underside of the patio table cover by surge stitching all the raw edges of the fabric to make sure that there will be no loose threads or unraveling over time!
