I have to admit this was purchased to help keep my cats from getting on my keyboard while I am working from home. For that reason alone it works very well. It uses two feet that slide on and is sturdy, sheerness - sometimes both the cats and I forget it’s there. It’s not very thick , but thick enough that it does not bend. If sitting in a bank teller window (old school height) this is a good size.If sitting on a desk I don’t see it as being a good height ( a little on the short side).
