My basement floor is very uneven thanks to a waterproofing job, and as such, any desks or shelves I put against the wall are on a slant. In some places, the feet are completely off the floor! These rubber furniture levelers make a great, barely-noticeable way to even the heights out. I love that they can stack together to be as tall as I need, and the angles mean that literally every height is covered. The rubber has enough friction that they stay in place, and they're solid enough that they aren't collapsing under the weight of the furniture. They look much classier than a book or hunk of cardboard shoved into place, and there were plenty of these in the package for all my desks and then some!

For years I've used shim pieces or matchbooks, or whatever else was lying around. This is a much more professional option that are practically invisible once set under the table/chair/whatever.

My house was originally built in 1890 and things aren't exactly straight here, lol. These function great and the rubber prevents tables from sliding and they stay put. Really happy with this solution and more in the box than I'll ever need. Highly recommend.

I live in an old house with a pier and beam foundation that is terribly uneven in places. If I level a piece of furniture, it is only a matter of months before it is rocking again. These levelers are made of a tough rubbery material with a textured surface. They are very easy to place in position and adjust. They should also do a good job of staying put. I am very pleased with them.
