Perfect
Size: 16 Inch
Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.

Good Look and Adjustable Heights
Size: 16 Inch
Legs are sturdy enough, but to hold a small marble top, it required additional glue to secure the "wobble." Adjustable height was excellent and material quality good. Easy enough to install and works well for a table that I don't plan to move frequently.

Sturdy, easy, beautiful
Size: 16 Inch
Put these on a coffee table top and it was the perfect combination. It gives an industrial accent to a wood-centered room. Love them.
