Universal Office Chair Caster Wheels Set of 5 Swivel Vertical Axle Heavy Duty & Safe for All Floors Including Hardwood 3" Rubber Replacement for Desk Floor Mats

I've had these on a kneeling chair for over a year now. No issues.Rolling is very smooth; especially on the wood floor in my office. I was also worried that the rolling would be TOO good and that I'd slowly drift when sitting still at my desk. However they stay in place and I don't find myself rolling away from my desk.

Smooth rolling and no scuffs

Hard to move the chair when seated. Noisy. Not recommended.

I've been on a quest for sometime with these roller blade wheels. So far, these are the best construction (enclosed dual bearings) and for a price that's currently unbeatable ($28).No more little balls scattering around the floor when the other ones got lose and bent. Especially for heavier people they were particularly bad, or chairs if they didn't have a gas cylinder under the chair to coushin when the person sat down.Definitely these dual enclosed ball bearings are the way to. I've had these now for over a year and the only miff is that one of them squeeks every now and then, but quietly. The other ones with those caged balls of whatever, I was buying new sets every 6 months. These I bought in June 28 2022.

Tis is my second set of "roller blade style" casters. The first set leaked grease along the exposed bearings. This product has a cover over the bearing and, at least from the diagrams, a much better design that I am looking forward to.My first impressions are that these are MUCH more quiet than other brands - virtually silent, unlike that grippy rubber sound. I was also worried about the translucent wheels vs black, but I must say, these look great. They appear virtually black unless light shines though them somehow. In other words, they were transparent in the hand, but on the char, the lens effect seems to make them mimc the color of the floor but darker. The look great.They also feel better than the other ones I've tried in the chair. While the chair glides effortlessly, it does not move around with the smallest motion. It's basically ideal.
