Diffrient Smart

Designed by Niels Diffrient

The Diffrient Smart chair is an intelligent mesh task chair with a striking linear aesthetic that complements any environment. Engineered to provide automatic lumbar support for every user, as well as simplicity and ease of use, Diffrient Smart offers comfort, style and flexibility. Diffrient Smart was created by designer Niels Diffrient and, like Humanscale’s Liberty and Diffrient World chairs, uses Humanscale’s revolutionary Form-Sensing Mesh Technology and mechanism-free recline for perfect support for every user.

About Diffrient Smart

Diffrient Smart is a minimal mesh task chair that is a striking addition to any modern office thanks to its linear, geometric design that easily integrates into any environment. With a unique U-shaped back and minimal lines, Diffrient Smart also features arm rests that are attached to the back of the chair, so they move with the user for dynamic support. Its brushed aluminum finish ensures Smart’s longevity, while its automatic recline support every individual that sits in it. Diffrient Smart’s revolutionary tri-panel mesh backrest offers instant support and allows the user to engage in healthy, ergonomic postures.

Ease of Use

Featuring Humanscale’s weight-sensitive, mechanism-free recline, Smart automatically adjusts to the body weight of each sitter to provide perfect recline support. Using the laws of physics, all the user has to do is sit and the chair will provide the correct amount of tension for their shape.

Linear Visual Design

Free of manual controls, Diffrient Smart has a striking, sleek aesthetic, and its U-shaped back makes it the perfect fit for any high-design environment. With linear lines in the backrest and strong mesh for maximum support, it’s the ideal task chair for the modern, active workspace.

Tailored Backrest

To ensure every person who sits in Diffrient Smart would have perfect lumbar support, Diffrient created a tri-panel mesh backrest to automatically adapt to the user’s needs. Eliminating the need for complicated adjustments and external lumbar devices, Diffrient Smart uses Form-Sensing Mesh technology for easy, ongoing comfort.

Customer Reviews

Amazing comfort
for those who sit in a chair all day.. There is no other chair...

Great chair, comfortable, solid back support
I spent a lot of time researching which chair I wanted to get before I settled on the Diffrient Smart chair. I wanted a chair that was well built, comfortable, ergonomic, had adjustable seat depth and adjustable arm rests and a mesh backing. This chair suits all of my needs and has exceed my expectations in it's simple but effective design. The design is also sleek and beautiful. This is definitely not an ugly looking chair. I have an office chair at work made by rival Herman Miller that I've not been very fond of. My office chair has so many knobs and buttons, I feel like I'm operating a rocket ship just to be able to get comfortable in my chair. The Diffrient Smart chair is the complete opposite of my office chair, because it's simple. There is one knob to adjust seat height, that's it. If you want to recline, just recline. My back instantly feels comfortable and supported when sitting in this chair, and the 3D mesh backing makes my back feel cool, never overheated like in other chairs. The comfort of this chair is a big plus a well. I feel there are a lot of chairs out there that throw out comfort for ergonomics. Thankfully this chair does both. Overall, if you're looking for a well made, comfortable and ergonomic chair that you want to last a long time, look no further than this chair.

Fantastic, durable and incredibly adjustable chair
This chair was well worth it. I purchased the higher chair that allows for vertical adjustments you can't find in another chair. The design is also a fresh modern look with a nice color accent.

Just love it
Best office/task chair I've had the pleasure to sit in. Comfort, style, simplicity, colour, versatility - the arms even lower enough to play guitar comfortably. I couldn't recommend it more highly.

Design Story

"As a result of seeking a really good adjustable arm, I was led in a direction that would allow me to do that in the best mechanical and serviceable way. That led me to the dominant visual feature of the chair... the horseshoe shaped aluminum support."
Niels Diffrient, Designer


Following the success of Liberty and Diffrient World, Niels Diffrient developed Diffrient Smart to offer a chair with strong visual features. He wanted to create a task chair that was in line with Humanscale’s philosophy of designing seating that is simple, beautiful and effortless to use. Diffrient Smart has straight, bold lines and a timeless horseshoe-shaped aluminium support, so its suit any environment it is placed in.
