This cover is heavy duty and we used it over our 70 inch table with six large chairs. We live in Minn. so we have snow.
The clips worked all winter to keep the cover on and the snow off.  We used some large domed shaped Styrofoam on top of the glass table under the cover to help the snow slide off.  We had seen some other covers that included some kind of flat bottomed dome with the cover to do this.  I think you can purchase these domes??? But a good idea if glass table and lots of heavy snow.  This cover is a little over sized but worked great to cover all of the 6 captain type chairs. Will hold up for many years I think.
