I've never owned an IKEA desk, but can vouch for VIVO's frames - I'm typing this comment using a mechanical keyboard on an IKEA Karlby countertop mounted to a set of VIVO V120EB legs and am experiencing minimal wobble (minimal desktop wobble, no monitor wobble thanks to the gas-spring monitor arm I have).

I also have my desktop at ~49" off the ground, including castors and a 1.5" thick countertop, and I've read that no standing desk has 0 wobble at this close to maximum height.

I have this one with an ikea kitchen counter top and it is an amazing combo, Highly recommend https://smile.amazon.com/gp/product/B073K1JSW7/ref=ppx_yo_dt...

If you still have the Ikea one, that was caused by a fairly wide-spread issue with the power bricks. They'll replace them under warranty with just an email with some info about the brick.
