We won't be beaten on price


Diffrient World is Humanscale's first foray into all-mesh task seating. Designer Niels Diffrient wanted to create the most minimal, full-function task chair ever made. With an innovative tri-panel mesh backrest that provides custom back and lumbar support and a lightweight design, Diffrient World is, like all of Humanscale’s products, simple, beautiful and functional. The design eliminates the need for traditional mechanisms, instead using the laws of physics and the sitter’s body weight to offer perfect recline for each individual sitter. Diffrient World offers the ultimate user-friendly sitting experience.

Niels Diffrient designed Diffrient World to offer ease of use and effortless functionality. With weight-sensitive recline that adjusts automatically and armrests that are attached to the back of the chair so they move with the user for ergonomic comfort, Diffrient World provides custom comfort for every sitter. A high quality, affordable task chair with minimal parts, Diffrient World was built with longevity in mind and will look as good in ten years as it does today.

In stark contrast to other chairs, which require many adjustments, Diffrient World achieves the pinnacle of simplicity of function. Users can take full advantage of its ergonomic benefits the moment they sit down, without even thinking about it.

So instead of managing chair training for today’s and tomorrow’s employees, organizations can focus on managing their business.

And with just eight major parts, Diffrient World is built to last. Requiring minimal maintenance, Diffrient World comes with a 15-year 24/7 warranty. In other words, the chair’s simplicity reduces the need for ongoing maintenance and repairs, making it even easier for an organization to own.

Excellent office chair.
Very pleased with this purchase. Prompt delivery. Well designed and made. Comfortable with good back and seat support.
Review by Michael B.
Superb chair and superb service, so pleased with my purchase!
Review by Sarah J.
Wish I'd bought it a long time ago
I'd seen this at a high street retailer a few years ago, and wanted it but didn't think I'd use it much. When lockdown started I used a dining chair for my office work and got back ache, so ended up buying this. It's incredibly comfortable, doesn't get sweaty as it's mesh, and the backache stopped on day one. It also looks good in white which means by combined study / bedroom doesn't look too much like an office.
Review by Dylan W.
Excellent office chair and quick delivery
My chair came in two days, which was great. It comes in two pieces and is very easy to put together. It is extremely comfortable and I'm very pleased with it. My husband liked it so much that he bought one too.
Review by Nikki M.
The most comfortable lightweight chair I own
The combination of comfort, simplicity and lightweight make this my favorite chair
Review by Emory O.
What a difference!
Very comfortable, supportive, great office chair
Review by Dina O.
Beautifully made
Smooth-rolling, smooth wheel legs (for perching your feet upon), nicely adjustable with arms that stay out of your way. My only complaint with this chair is that, because of the way I perch at the front of my chairs, and because this one is simply the mesh (which makes it supremely comfortable for sitting for long periods), with no hard reinforcement at the front, I often found myself slipping off of the front of the chair. That said, my husband and my son also found the chair super comfortable, and my son excitedly took it for his own!
Review by Catherine K.
Good chair for the price
Seat is a little hard without extra cloth and arm rest do not recline with the chair but overall way better than the chair I had before.
Review by Jacque R.
Absolutely the BEST
Absolutely the best, most comfortable and low back friendly desk chairs ever! Although they are not inexpensive, they are well worth the investment!!
Review by Erika S.
Sturdy chair that is comfortable and well built. Plenty of adjustable level for many sitting options. Very pleased with this chair
Review by Adam F.
Lightweight and comfortable
Well made product yet very light. The mesh sets still maintain a firm seat and give great air flow.
Review by Daniel S.
My back feels so much better
I started noticing my back pain literally just disappear. It was amazing. I'd totally recommend this chair to anyone that needs to sit for a long day.
Review by Raul A.
Great office chair!
Bought this for my home office. Was looking for something comfortable, supportive, and breathable. Got all of that and more with this chair. It's very comfy, even for extended period of sitting. Not a lot of dials or lever to fidget with to adjust it either. Set the seat height, and adjust the height of the armrest and the chair adjusts the seat and back position as you sit and get into the desired level of recline. Paired with their keyboard system, you've got a very comfortable work station. Was a little worried about the sturdiness of the material that the seat and back are constructed of but so far, they've held up great. Been using it daily for almost two year and it hasn't worn or stretched a bit as far as I can tell. Did have an issue with the seat height lowering when I laid back in the chair, however, one call to Humanscale and a replacement part was sent out immediately. Very satisfied.
Review by Ryan B.
An Amazing Chair!
This is by far the most comfortable ergonomically-designed chair on the market today. When my wife had back surgery, we needed to find a chair that would contour perfectly to her spine and provide ample support without causing pain or fatigue. After lengthy research, we decided on the Diffrient World chair and have never regretted the decision to buy it. The chair surpasses everything else we tried and allows her to sit for hours without any fatigue or discomfort. In fact, we have to thank Humanscale in part for her speedy recovery. We were so pleased with the Diffrient World chair, that we purchased one for every member of our family and use them daily for hours of reading, writing, and work at the computer. This is definitely a gem of comfort and design that stands out from all its competition.
Review by Wayne D.
Functional simplicity
I have had the pleasure of sitting on this chair for very long workdays for a couple of years. It lacks manual adjustment intentionally, but the seat and back conform to and support my 5'9" frame perfectly. The arms are the right height and length, and the flexible automatic lean to the back enables me to stretch frequently without having to flip a switch or turn a knob. That might be my favorite aspect of this chair.
Review by Patricia R.
My husband loves his new chair!
This chair fit our modern decor and my husband's picky comfort standards. I love the mesh back and seat and it doesn't fill up the room, it's slim line silhouette opens up the room and it moves around from carpet to wood easily.
Review by Kathryn C.
A beautifully functional chair
I have had this chair for almost four months and it is the best chair I have ever owned. I love the design, the clean look and the fact there are not an abundance of pulleys and levers, you simply sit and the chair does the rest, it provides excellent lumbar support and I no longer have back or leg pain. It improves my posture. It reclines and moves easily. I recommend this chair without reservation.

Review by Ann C.
Perfect in Every Way
We have these chairs at work, and I had to have one for my home office. It is, by far, the most comfortable office chair in which I have ever sat. It provides support in all of the right places. I would recommend it to anyone. It is beyond worth it.
Review by AKILAH S.
Modern Comfort
Excellent styling and slim profile fit in our modern style home nicely.
Review by Kathryn C.
Diffrient chair both at home and at work
As I have a bad back and am often sat at a desk, I initially purchased this chair for my home office, have had it for over 4 years now, and I love it. A few months ago at work, a well-known workplace ergonomics assessor and supplier came to site and reviewed the office chairs. They recommended one for back and arm support for me, and within weeks of receiving it, my back pain worsened and I had a further health complaint. On reviewing the possible causes of this new complaint, my GP advised that it was more than likely this new office chair that was doing the damage. The supplier agreed to take the chair back and offered other solutions, but I held fast and said that I only wanted a Diffrient chair, identical to the one at home that I had been using so successfully, and the supplier purchased one for me. Quite a few people at work are now interested and trying it, so it might become an option for the future. At any rate, my back and other issues are now resolved and I am very happy to have this chair both at home and at work!

Seat of Power
A bit of an exaggeration but it is a terrific work chair. I'm a freelance writer and I spend many hours seated in front of my Mac. The Diffrient makes it all more comfortable and productive.
Review by Charlie A.
Great chair
Easy to assemble super comfortable and great looking chairs. These can be used in many settings and will fit in without issue.
Review by Gary O.
A Big Step in the Right Direction
First, I love the all mesh concept; it keeps the chair cool and feels like it conforms more to the body. Second, I like that there are few adjustments. However, the slickness of the mesh, and would venture other upholstery type makes me feel like I am sliding off the front of the chair as I lean back. Missing is the tilt of the seat pan as one reclines. Perhaps the guides that allow for forward movement during recline should have an upward swing to counter this and add to the feel of reclining.

Humanscale Diffrient Chair - Features

Invisible Recline Mechanism Diffrient World uses the laws of physics and harnesses the user’s body weight to automatically provide the right amount of recline for every individual, every time. Its groundbreaking mechanism-free recline action leverages two parts of the chair’s frame to provide automatic, balanced support throughout the full range of motion for maximum support.
Responsive Bracket Diffrient developed the chair’s back using the laws of physics, which eliminates the requirement for a separate lumbar support, which tends to create a pressure point and requires manual adjustment. With patented Form Sensing Mesh Technology, the backrest perfectly conforms to the sitter’s entire back as if custom made for them.
Sitting on Air A truly lightweight chair, Diffrient World replaces the standard cushion seat with a low-abrasion, non-stretch mesh. To maximize comfort, Diffrient eliminated the front edge of the chair, solving a perennial problem of hard edges placing pressure on the knees and contact stress behind the thighs, allowing long-term comfort and total supports for every sitter.


"My goal is always to design chairs that are so simple to use that the functionality is often invisible to the user." - Niels Diffrient

  • Our textiles attach to the cushion without adhesives, which prevents wrinkling over time and is better for the environment.
  • Our arm caps feature a separate foam insert, so they will not tear.
  • Our plastics have a texture that prevent scratching.
  • None of our chair surfaces are painted or treated, so there’s no chipping or scratching.
  • We go to great lengths to ensure all the components of our chairs hold up to wear and tear, while maintaining a minimal visual aesthetic.
  • We use fewer parts in our ergonomic chairs to reduce the impact on the environment.

The Humanscale Difference

We develop our chairs without knobs and levers, so they’re incredibly easy to use. All of our chairs allow the user to change postures effortlessly without operating any manual controls. Designing ergonomic chairs that are easy to use ensures that they are used in a correct, healthy way.
Most office chairs feature arms that are attached to the seat, which do not provide support when the user reclines or moves from posture to posture. Humanscale designs all of its desk chairs with the arms attached to the back, so when the sitter moves, the arms are in a healthy, ergonomic position every time.
A soft seat cushion is often comfortable for a short period of time but uncomfortable when the user sits on it for many hours. Humanscale’s seat cushions are engineered to be denser than our competitors’ to offer all day comfort. We also pioneered the use of gel in seat cushions. Because gel doesn’t compress, it supports the sitter’s body and maximizes comfort over many hours.
Humanscale ergonomic desk and office chairs are perfectly adjusted for every user, as if the chair was custom made for you. In lieu of traditional tension mechanisms, which can weigh as much as 15 pounds and be made of up to 40 parts, our task chairs use the laws of physics and the sitter’s own body weight. As a result, the chair automatically reads the weight of the user, allowing for the mechanism to provide perfect recline with the correct tension for every individual.
