OPTTICO Office Chair Caster Wheels Black 3 Inch Desk Chair Wheels - No Chair MAT for Hardwood Floor Needed - Rollerblade Style Heavy Duty Computer Chair Casters with Soft Rubber Wheels.

These wheels cost probably half of what I paid for the chair, but they are by far the best feature of it now. Roll quietly and smoothly over carpet (see note below) and vinyl flooring, and I haven't had any issues with the functionality of them. They installed super easily in my chair (a Furmax office chair from Amazon), so no issues there either. I have been using these wheels for 5 months now and put an estimated 750 hours of usage on them, and I weigh ~170 lbs.One note: I have been using these wheels on the carpet in my apartment (which is pretty cheap carpet), and it does tear up the carpet over time with frequent use. Yes, it's stated in the product listing not to use them on soft carpet, just figured I would give my experience since I did it anyway. I think it's wearing out the carpet because the wheels are grippy rubber/polyurethane and pushing the chair around causes the wheels to change direction frequently, and when this happens the wheels rub the carpet fibers in different directions and cause them to become matted. Again, this is stated in the product listing, but be aware that these wheels are not great for carpet with any pile greater than super low pile "business" carpet. If you use them directly on most residential carpet, especially cheap or softer carpet, it will tear it up over time.

Very smooth and made exceptionally well and will definitely refer this to a friend and very refreshing to buy from a small family business and not from China

I bought these for both my computer chairs. One is on tile and one on carpet. They are easy to install and make the chair roll smoothly and quietly. So much better than those cheap plastic wheels that come on most computers chairs. Definitely a must buy.

These replacements are great! One of the cheap hard plastic casters that came with the chair are awful (see photo), not turning well and often working against each other by not properly swiveling. I'm embarrassed that It never occurred to me to upgrade until one broke. The new ones swivel and are just amazingly better. I was afraid that the soft wheels might not want to swivel however even with my 230lbs these are smooth, noiseless and roll effortlessly. Just a bonus that they look great too. Do be aware, since I am a fairly tall guy I like the chair high but the height added by these wheels might cause a problem for people like my 4'11" wife that need a very short chair. Installation was super simple.

Please be aware that wheels makes the chair bit taller. Which is fine for my purpose.
