Ordered late Friday Evening, dispatched Monday, arrived Tuesday.  And that was with free delivery!  How's that for service? 
They were easy to assemble with the Allen key provided, and we couldn't believe the excellent quality - given the price.
Okay, so the chrome frames weren't as chunky as some we'd seen on similar tables in our local furniture outlets, but we'd turned those down because they were so heavy and cumbersome to move; especially as at home you could be trying to do so with a cup of coffee in one hand!
At one point we thought one of the table-tops had some minor damage, but it turned out to be a tiny wrinkle in the clear protective film that you peel off when everything has been assembled.
We can happily recommend these tables, and will now be browsing Wayfair's vast range again when next we need something for the house.
