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.

There is no side to side stability
Size: 28 Inch
This product was easy to assemble and install and came with all parts. The product itself is very sturdy, looks good with a nice industrial aesthetic BUT - there is ZERO stability side to side (lengthwise) as the plates which attach to the wood are too small. I have them set closer than the picture so it is not an issue of being too far apart. If anyone else had this problem AND FIGURED OUT A FIX FOR IT - please share!!

Fairly stable. Good value for the price
Size: 16 Inch, Size: 16 Inch
Great set of stands. You have to tighten them pretty snugly to minimize wobble. Given they are metal they’ll have a little bit more give than solid wood. Even so,
a tall desk I built with them remains stable and level.
