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

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.¬†
