Tapis de cuisine anti-fatigue

Last one I bought stayed in place, this one particular brand moves around

just the right size and thickness

Love it

Specifications say it can handle up to 33lbs, but the monitor was only 26lbs and it failed. I got this for my 49" ultrawide monitor. The screw that locks in the tilt of the monitor was not strong enough to stop the screen from tilting down. It may work with a lighter/smaller monitor, but it does not with the ultrawides.

The mount is well made and sturdy. On my desk (an AnthroCart Elevate standing desk, the desktop's surface is very subtly textured and very solid. I noticed that even when fully tightened, the clamp can rotate if an off-center force is applied to the arm, perhaps because the desktop does not deform under the force of the clamp. I don't move the arm often, so I'm watching to see if I need to add a non-slip insert (e.g. coarse sandpaper between the clamp's jaws and the desk surface to stop this rotation and prevent the clamp from working its way off the edge.
