I had this bracket mounted on an IKEA Bekant high table with 2 x 24".
Of course, an IKEA standing table is not as stable as a comparable model that costs four times as much.
So of course the mount, or rather the screens high up, automatically wobble with it.
When sitting, the wobble is within the normal range of the weight of two monitors, when standing it is noticeably more
(1-2cm, depending on how hard you bang your toes ;-) ).
But the thing does hold perfectly!
And I hope my feedback helps you. Sincerely
