World Chair Cylinders - How Tall Do You Want Your Chair to Be?

  • The Humanscale World Chair comes  Standard with a seated height range of 16" to 21".  This fits 95% of the population.
  • Shorter users may prefer the Low cylinder with a seated height range of 15.25" to 19".
  • Taller users may prefer the Tall cylinder with a seated height range of 17" to 22.25".
Buy Smart: The World Chair will fit most people but taller users should keep in mind that seat depth must be long enough to support your thighs.  Users above 6'3" may find this chair too shallow for more than occasional use.

Diffrient Chair Casters:


Your Diffrient World Chair comes standard equipped with hard casters that work well on carpet or plastic chair pads.

Soft casters for hard floors and stationary glides are optional.
