I have an IKEA desk that rests on four white legs. It does the job but it’s always been rocky and shaky. It’s especially noticeable with 3 monitors dangling and shaking around. I bought these little super heroes and my desk feels solid. I mean SOLID. If my eyes were closed I would just assume it was a counter top. These are amazing but you do need to make sure they can actually clamp on in the back. Some desks have little bars that might stop these from working unless you purchased a small piece of wood to fit underneath it.I fully recommend these if you are rocking the IKEA flat desk tops. This might prevent you from needing to drill support brackets into the walls.
