I loved the look of this table, though the reviews saying the surface was vulnerable to scratches were right. Solution: I bought two pieces of 1/4" plate glass, one to cover the table when folded, and another the size of the leaf to use when it's in place. That didn't come cheaply, but now I really love the table and have no fears about damaging the surface with heat, liquid, or scratches.
The leaf mechanism is quite slick. I didn't understand how it worked from the description or reviews, but I'm pleased with the design. To use it, you pull the table halves apart to reveal the leaf stored underneath, folded in half. It's not removable. You flip it over (it's connected to the table under-frame) on its pivots, unfold it, and it's right where it needs to be.
I do have two complaints. One, there was some damage when it arrived, though not enough to go through the hassle of returning it. There are some pieces of wood that are not visible unless you look under the table, and one of these was significantly damaged (though not structurally). The other complaint I have is that the trim on the leaf was misaligned and not well-attached (it's attached with skinny nails to the leaf) though I was able to fix this completely with a few blows from a hammer.
Overall, I'm very happy with my purchase, once I bought the glass and fixed up the trim. The table is very solid and a wonderful dark color, plus I like not having to find a place to store the leaf.
