This Protective Cover is a perfect fit with extra room to put a Large plastic tote under the cover which some what cone shapes the set up for water run off and has clip straps at the bottom to the table legs to keep it in place and keep wind from blowing it off the table  chairs. The material that the cover is made of does seem to be heavy duty enough  breathable but yet waterproof and hopefully (Time will tell), that it will protect my round table  6 chairs from the elements. So far it’s Great!
