Question: How is the glass top attached to the table legs ?
Document: The box was a bit tattered on delivery, and the delivery process was a little hassle, but the table looks great. The glass and legs were in perfect shape. It was easy to set up and is sturdy. The walnut legs look great. It will definitely take two people to assemble and get turned right side up. The glass is heavy!
Great table! Love the look and quality. Very sturdy for a glass top table. Great furniture for the price paid
I purchased the glass dinning table F/WLN,70.7x35x30 and very happy. The thickness of the table is approximately 1/4 inch and has a beveled glass top and is sturdy. The delivery took about 10 business days and ships directly from the vendor. Arrived in excellent condition and easy to assemble. You will need two people to adjust the pedestal to the table and to turn the table right side up.
One of the reasons I bought the table was because of this promise. Again good for them and unfair to us.The table itself is beautiful, well made,  has the feel of modern airyness we wanted. The design belies the look of instability - matter of fact the table and its top are screwed together and are one unit after assembly and are rock solid.
The table was delivered today, only after we had to write and ask where our table might be. We finally tracked it down to find out that the delivery company had it in their warehouse for a while and were "just" waiting to have more deliveries pooled to deliver from Reno over the mountains to Tahoe. Good for them, not so fair to us.The seller stated in the invoice from amazon that set-up of the table is included.
Answer: There is a metal thing attached to the glass that you screw the legs in to.
