Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Fantastic for furniture making
Size: 16 x 18 Inch, Size: 16 x 18 Inch
Frankly, I didn't know what to expect... But these turned out to be exactly what I was looking and hoping for. These table legs were so easy to assemble. They come with adjustable feet so you can have a level table no matter your tabletop shape or floor situation. Assembly is done with a simple Allen key. Printed instructions are included with simple diagrams that are so easy to follow. Also, the seller provided all the hardware needed and more! They provided multiple black screws of different sizes that fit through the top holes of the legs, making it so easy to screw the leg base into the table top (use an electric drill with a Philips head for that). I had zero issues with any of the hardware provided. The base has a nice smooth black powder coat application on the metal. Shipping was so quick too. Seriously, if you are looking for a low cost, easy to assemble, good looking, and adjustable end table base, get this. I ended up making plant stands with these using some tree slices I had as you can see in my photo. 10/10 highly recommend.

Easy to put together
Size: 16 x 18 Inch
Great legs and look great with the table, however, the legs connect to a peak and is not level. A friend made me some spacers on his 3d printer so I could use them.
