I finally assembled the table, which wasn't difficult, but the instructions, just visual, were. There was a missing gasket according to the schematic, and I ordered a replacement set of hardware, along with a replacement metal support, which came marred originally.  The customer service representatives were lovely and helpful, and my replacements came quickly, but still with the missing gasket. I hope the table will remain steady.  It's perfect next to my new recliner in a den.

Also, I wish I had known the table was made in China.  I ordered it because the information said nontoxic and eco-friendly.

It was difficult to find a phone number to contact Wayfair, but I googled Wayfair customer service tel. number and found it.  It should appear on the home page. All in all, my experience with Wayfair was positive.
