The gold standard in office seating, the chair redefines the concept of traditional task chairs. Designer Niels Diffrient aimed to design an office chair that automatically adapts to the user, allowing them to move freely from posture to posture.

Have this chair at work (with headrest) so ordered for my office at home now we’re working from home more. It’s very sturdy and comfortable. Good lumbar support which was the primary reason I spent the money - I knew what I was getting for the price. Noticed an immediate difference with my sciatic pain. Assembly is very easy - no tools just attach the base to the seat. The thing I like about this chair is you can lean and the arms lean with you. Also the arms are adjustable.. Sandy. Aurora, IL.

Discover the closest thing to sitting on air. Humanscale’s first foray into all-mesh task seating, innovative backrest provides custom lumbar support for every sitter at any stage of recline. It is accomplished by replacing traditional bulky mechanisms with the laws of physics and the sitter’s body weight. As a result, all the sitter needs to do is sit down to enjoy the ultimate sitting experience.

Love the chair. Looks great and extremely comfortable. Also easy to assemble.. John. NY. Mon Apr 19 2021
