LONGADS 5 Packs 3 in Office Chair Caster Wheels with Brakes for Hardwood Floors and Carpet,Heavy Duty Quiet Swivel Replacement -Made from Soft Premium PU Rubber,Rollerblade Style w/Universal Fit

My Ikea office chair worked great for several years, but the casters don't roll very well. Furthermore, once I got an under-desk elliptical exercise machine, I suddenly needed the chair to not roll backwards. After trying caster cups and even installing a handle on my desk to hang onto, I finally decided to look for a better solution.This set of roller blade style casters with built-in brakes seemed to fit the bill, but unfortunately Ikea uses a slightly smaller stem size than the 7/16" (11mm) stems that are almost universal in North America. So I got a 7/16" drill bit and slightly enlarged the sockets in the chair legs. The new casters then fit perfectly, and now the chair works great for my purposes.The brakes are engaged all the time because I usually don't want the chair rolling around. With these brakes, the chair really stays rigidly in one spot and I can do my leg exercises unimpeded.If you disengage the brakes, the chair rolls quite smoothly, and if you engage the brakes, it won't roll at all. I love these casters; they do exactly what I needed and so far, after a week's use, seem quite well built and stable.If that changes, I'll update this review. But so far, they seem to be a great product at a very good price.

Muy buenas ruedas, no hacen nada de ruido, no rayan para nada la superficie del piso, los "frenos" que tienen por rueda estan perfectos ya que no deja mover la rueda...excelente compra!!!

I needed to install the brake wheels to my office chair used for gaming. Specifically for use with a rudder pedals for the Flight Simulator. It worked.

Nice Chair Wheels..Good Product...Strong lock...if u want to stop continuous moving your gaming chair or office cahir while gaming or working which is very irritating for me ..must buy this product

These are easy to attach to your chair as a nice upgrade, they're a higher ride from the floor - see my attached photo for size comparison to regular wheels. They greatly decrease friction even on my carpeted office floor. They're sturdy and have flawless spinning/ gliding.My only concern is that the breaks stick out horizontally when unlocked, so you have to be careful not to scrape your ankles.I would absolutely buy again.
