As an updated version of the Diffrient World chair, the World One chair is a more cost-effective chair with ultimate ergonomic support. This is unlike traditional office chairs because it uses the laws of physics and user’s body weight to adjust the recline. A flexible yet strong non-stretch mesh on the backrest and seat offer optimal support.


Product Reviews


seat comfort

Seat Comfort

The seat on the World One has a frameless front edge that eliminates contact stress behind the knee. The waterfall edge offers long-term comfort, and also provides weight distribution. The wide seat makes it feel very spacious. The mesh upholstered seat doesn’t have much flex in the mesh to help create body-fitting contours.

Back Comfort

The backrest has a built-in curve for your lumbar area. The curve in the back is very pronounced and the mesh is really flexible. The tri-panel mesh backrest creates three different zones, which helps to conform to the specific person that is sitting in the chair. The mesh allows you to sink into the back and then the pressure of the mesh flexing will provide the support you need. This backrest features an extra pivot motion that automatically adjusts to the changing needs of your spine. This gives your chair a bit of wiggle so it will adjust to your back position, without you having to recline.




The World One chair was purposely designed with only a few functions. The idea behind the chair is to have a minimalist design that requires only a couple adjustments for you to be comfortable. Humanscale wants you to be able to get in the chair and be comfortable and ready to work right away. The World One chair comes standard with two adjustments: seat height and seat depth. When you recline the backrest, the seat moves but it does not keep you in the same position to simply rock back. Instead, it pushes the back of the seat up. The idea is to open your hips as you recline, which is thought to be an improved posture to the standard rocking motion. Height adjustable arms featured on the chair adjust so you can comfortably rest your arms at the perfect 90-degree angle.


Humanscale covers the World One chair for 7 years on all parts and componenets. The warranty covers the chair for 24/7 usage and for people up to 300 lbs. The upholstery and arm pads are an exception to this coverage. They have a coverage period of 3 years and are covered for single-shift use. One aspect about Humanscale’s warranty, that separates them from a lot of other brands, is they will make on-site repairs for you, if you are located near a Humanscale authorized dealer.
