This was a terrific purchase (and guess on my part for sizing) to cover TWO of the Crosstown tables that I also bought from WayFair to make one large table.   Even with TEN chairs around the table, the cover fit perfectly!
The cover comes with very sturdy and easy-to-use clips to hold them down to the legs of the table or chairs.  
I left my 'center piece' bowl on the table, and easily covered that with the Dining Set Cover also!
I did have to remove the table-top heater from the top of the table, before placing the cover over the tables. 
My only complaint would be the rather obnoxious "Brand" label on the front of them.
