X-Wheel Blade Casters represent a breakthrough in seating technology and comfort.

The wheels on your chair are the foundation that creates core stability and leads to healthy, smooth, ergonomic movement. Featuring 100% rubberized blade wheels and a free ball-bearing core, X-Wheel Blade Casters are quieter and smoother. They work better on hardwood and pile carpet alike, and they are more gentle on tile, hardwood, vinyl, carpet, and almost any surface. Ball-bearing swivels spin easily, preventing scuffing and scratching. And they look great! Put, for a small investment, you can upgrade your chair’s performance and enhance your seating experience.Â
