Bests & Worsts Reviews from Amazon

These wheels seem to be very well made. They're heavy. That's mainly due to the thick steel armature and the general quality feel of the materials. They roll very smoothly and swivel much more easily than standard cheap plastic wheels. Though I have a hardwood floor, I can imagine that due to their diameter they'd roll nicely on carpet. They're a tremendous upgrade from your average chair wheels. Due to their quality and being perfectly as-described, I've given them 5 stars. But I'll be returning them due to 2 issues that are specific to my situation. But they may also prove to be issues for you, so I figured I'd make note: - Maybe it's just me, but nowhere in the description do I see the height of the wheels mentioned. I bought these along with a new chair. The manufacturer-supplied wheels added 2" to the overall height; These add a hair over 3.5". Keep that in mind before purchasing, because in my case they made the chair too high, even at its minimum adjustment. - As I said, they roll very smoothly. Too smoothly, if your floor isn't level. Mine is not, but only by a small margin. Rather humorously, the chair would have a tendency to drift away from my desk if I took my feet off the floor. Needless to say it would also escape when I got up. In that regard the high-friction cheap wheels are better.
