Apr 28, 2013 at 5:57 comment added DMoore That is a math question. Maybe for another stackexchange. You have four legs, your table is a certain weight, and the disks are a certain size. The problem is it is hard to get a calculation for the compression of the "rug" under it... If you have a 1000 pound table supported by 4 legs with 1/2" settings then you have a force of 318 lbs/inch(squared) on the rug - in 4 small spots. Change that to 2 inch discs and you are at about 20 lbs/inch (squared). Your discs need to be solid enough that they distribute the weight evenly though.
