The amzDeal Office Chair Castors are a great upgrade for any compatible office chair. I switched the plastic wheels from my new computer chair, which after a month were already getting stuck, and after just a couple days I am already noticing a big difference. I use them on carpet and the biggest improvement I have found while using these new castors is no longer are my wheels digging in and getting stuck when changing direction.
The castors themselves feel very sturdy and smooth as something should that has a weight rating of up to 350lbs. The polyurethane wheels remind me of roller blade wheels, quite possibly could be just that, are very quiet as I've tried them on carpet, hardwood and tile, dont leave any marks and grip well even with rapid movements/direction changes. My biggest positive about these Office Chair castors is that amzDeal has installed them with a removable nut and bolt combo for easy wheel removal so if anything like hair or dirt gets caught, it makes it super easy to clean. Installing the castors was very easy and I had no issue. To install them I just had to pull the old ones off and push the amzDeal Castors on until they click. Once installed your chair will be a little heavier as the castor frame is metal and not plastic however I like that makes it feel a bit more planted and also most likely will sit a bit higher so if your chair doesn't have a height adjustment you might want to think about that.
Overall I am very happy with these Office Chair Castors from amzdeal and if your looking to save your floor, be a little quieter, or just want a smoother experience you should check out these castors from amzdeal.
