What stands out about both of these chairs?
Environmentally friendly - Humanscale chairs are very environmentally friendly. Many chairs are BIFMA Level 3 Certified, which is the highest level of furniture sustainability. Many are often SCS Indoor Air Quality Gold Certified, which is also the highest level (meaning no off-gassing).
Like all Humanscale chairs, the sophisticated design eliminates the need for traditional mechanisms by utilizing the laws of physics, and the sitter's body weight to give the perfect recline.
How do the World One Chair and Diffrient Chair differ?
World One only comes in black, while the Diffrient World Chair comes in a variety of colors. Otherwise the chair is very similar in fit and style.
We do offer Diffrient Smart Plus Chair - this one has a wider seat if it is needed. We also over other "Big and Tall" options on our website.
