WOW, very impressed. I bought three sets at the price, and may order a few more sets. I used one set for the office chair and also use them to make side tables for my patio, I use a "chunk" of tree trunk, put the chair wheels on the bottom and voila, a table. I also use them to replace the stubby legs on my large ottoman. Much more convenient having wheels.

These guys work great, buyer beware though - the white is only on the wheels, the axel shrouds are chrome. For my chair they look nice, but for others, you might want to go with black instead.

100% what i wanted......

Smooth, great plastic quality; fit on my Herman Miller Aeron right away perfect fit.

works great on my office chairs

Glad we could replace a caster instead of buying another chair. Works great
