Mastery Mart Office Chair Caster Wheels for Hardwood Floors, Heavy Duty and Quiet Smooth Rollerblade Wheels for Office Chair, Universal Size (11x22mm), Suitable for Most Chairs

As described, they work very well with my chair.

Got these to replace the original wheels on my sewing chair. I love them! They roll so smoothly from machine to machine. 100% worth it!Edit: Updated with photos of how nice the wheels are, and the state of the old ones. Used and abused! Lol

These casters look nice attached to my chair, just like they belonged there. They roll smoothly and quietly. Excellent choice. A whole lot better than the original, hard plastic wheels that came with the chair, that's for sure.

Fantastic, much smoother movement on carpet mat

Seem to be good quality, quiet, smooth. Value for money questionable since competitor is selling for a lot less. I'd buy again if the price were comparable and competitive.

I had installed new hardwood floors. To protect my new hardwood floors from my office chair's plastic wheels' scratching risks and instead of using a floor mat that would hide my new hardwood floor, a friend suggested rubbery roller blade type caster wheels for my office chair. Most products featured one wheel per stem. I sought a product that featured two wheels per stem to better distribute my weight and thus, decrease risks of damage to my new floors.This product was one of the few products that fit my criteria. The sellers' photographs and descriptions were informative, detailed, and encouraging. Like other reviewers, compared to my chair's former plastic wheels, this product's wheels enable my chair to more easily glide across my new floors, which suggests less friction between these new wheels and the floor, and they're quieter, compared to the former wheels.The wheels' polyurethane seems a softer material that is less likely to scratch hardwood floors than other products' non-polyurethane composition. Each caster seems well assembled. This product was priced lower than other two-wheel per stem caster sets. After several weeks, I have not detected any problems with these new casters. I unreservedly and highly recommend this product.

I have been using my chair with the new wheels for almost a month now and they haven't caused any damage to the floor or my chair, if you have a plastic frame I would like to say I don't think singe wheels will hold up you will need the double wheels to even out the weight, I'm pretty heavy and haven't cracked my plastic frame with the double wheels. I saw a couple posts talking about how fast their chairs were with the new wheels and thought they were exaggerating, well they definitely were not. I installed them on my chair and pushed back to see if there was a difference and flung myself into the wall at the end of the hall. I saw people talking about having a height difference as well with the new wheels. I found that the new ones go in slightly more than my old ones so my chair is now slightly shorter. These do still collect hair in the wheels but are much easier on my floors, they even work well on my super bumpy tile. Overall, very good at saving my floors and rolling around. They are also very quite which is a plus.

Changed out the standard poopy plastic wheels with these. Chair rolls great, quiet and no floor scratches or marks. Would buy again. Snap in to the slot in 2 seconds.
