Bought them to support 400lb cnc. Used on a sleep number adjustable base. We move the controller around every once in a while, and it's extremely heavy.

Aneaseit soft silicone chair leg covers work great for our faux wicker patio set. Metal core leg was producing a small rust stain on the concrete surface after a rain. Easy to install and don't have any of the issues i stated above.

Sizing charts were very accurate. I wish they were 100% reliable.

The sizing of the x small is now 7/8-11/16 (22-26mm) which is too large for my stool legs. When dinning room chairs slide across tile grout the pads stick and actually come off. Tore within 1st week of using.
