Anti-slip ring for office chairs or bikes
Handy anti-slip ring for office chairs with wheels, great for use with crosstrainers like the Stepper. A standard office chair on wheels can roll away when you push off against the bike pedals of an Inmotion or Deskrider. Place the ring easily under the wheel of the office chair and the office chair will stay put. At the Cubii Jr. an anti-slip ring is supplied as standard.
