These things are great! Our twin girls started crawling and I was worried about running over their fingers when at my desk. So we swapped out the old caster wheels on my chair and put these. I wish I'd done it ages ago since my chair has always slid around too much on the hard wood floor (even with a chair mat). These legs keep it in place but I can still move it easily enough while sitting. Great buy for the price. And I don't have to worry about squishing little baby fingers!
Tip - I see some folks talk about how hard it is to pull off the old wheels. Instead of doing it by hand use a claw hammer to gently remove the old wheels. It makes it way easier.
