The Sumo Omni Chair has become a permanent fixture in my office. Certainly the oddest thing I’ve reviewed. This is one BIG chair. Very sturdy too. Getting a rip into this chair would be a feat. You’d really have to try and break it. Great for crashing on when you’re tired and zoning out. Only problem I have is the price but, it’s there for the quality. If you need one, by all means.
