Sytopia Office Chair Castors, 11 mm x 22 mm Pen, Set of 5 Wheels for Office Chairs, Quiet, Smooth Gliding, Suitable for Hard Floors, Parquet, Laminate, Carpet, Tiles and Floor Protection Mat, Black

Bought to replace standard issue Nylon wheels for use on a carpeted floor.The original wheels on my chair dragged rather than rolled in the pile of the carpet making it difficult to adjust my position relative to the desk and I believe this contributed to the base of my chair breaking twice in the same way at the end of the spokes.These wheels are very slightly smaller than standard office chair wheels so they reduced the base height of my chair. there is still plenty clearance under the chair and the chairs own lift compensates for the change.They fit standard 11mm wheel sockets in the base.AND THEY ROLL!! on the carpet the chair moves freely. It doesnt Glide but it is definitely not dragging or a struggle to move around anymore.First impression is that they are well built and roll perfectly on rental property carpet.If anything goes wrong. I'll be back here with an update.

I had to replace the base (legs) of my chairs and decided to get these castors along with a new base. I've sat in many office chairs in many different companies, but these are by far the smoothest glide castors I've ever experienced, and the build quality is solid. They are great from a floor protection point of view, with nice clear rubber wheel material. The height of the castors is a normal standard height as you would expect.From first impressions, a strong buy recommendation.

Really good. They are tough to install, there is a knack! They raised me chair ever so slightly as I wanted. They move really well and don't mark/dent my carpet too much. Perfect for a home office room.

Bought these to fit to my sons gaming chair as we have wooden floors fitted and did not want to damage them. They are fantastic, very smooth and the rubber is soft enough that i am confidant that they will not damage the floor. I was so happy with them i brought a second set and added to my office chair and removed the floor protection i was previously using in there. It has now been 2 months and no marking

Tough rubber wheels ideal for hard floors, smooth roll, much better than scratchy cheap plastic ones. As wheels have curvature like roller blade wheels they are less likely to stick in certain positions. So good I got another set for the wife.

Easy replacement for standard castors on the chair. These are so quiet and smooth it's like I have a new chair.

Easy install

Easy to fit and 'wheely' good.
