It's thick, level, and fitdperfectly with my 72 inch table. 
I was concern it will come broken like the one I ordered from another store but Wayfair assured it will not and if it does, they'll replace it. Luckily it came intact. 
However, Wayfair needs to advice their distributor to pack this stronger than what they have because by the time it got to me, I had to be very careful. The styrofoam started to thin out on one side that you can hear scratching glass to travertine tiles.
