The OM5 is the best chair in the world! #1 Comfort and Ergonomics The story behind it's creation: "Office Master challenged up-and-coming designer Francisco Romero of Phidesign to innovate a wholly new chair starting quite literally from nothing. The OM5 Series is the result of that call to action. By stripping away all restrictions on this talented designer, Office Master worked closely with Phidesign for nearly 2 years to bring this sophisticatedly simple chair to life." We've tried the OM5 at Neymarc Visuals....and we love it. Video Production by Neymarc Visuals, LLC Music Licensed (Audio Network)
