Another awesome review. You guys are really good at this. Your reviews do seem unbiased. Such a rare thing these days…

The Cosm high-back is amazing. The leaf arms are ok but the adjustable arms are much better in my opinion. I am 6'1" and 190# and the Cosm recline works amazing for me, it just swings so naturally. The head rest is a little low - I have to tilt my head way back - but the back support is amazing. The mid height is also a great chair, but the low back was way too low for me. I prefer the Cosm to the Aeron, Embody, Sayl and Mirren 2 (listed in order of preference).

I'm glad that someone finally sat down in the chair after 6 minutes. It was the climactic point I was waiting for.

After this review I was hesitant to buy the chair. However, when I walked into our local store and sat down it all changed my mind. Wow, this is a fantastic chair and for me, better than the old AEON line. You truly don't need adjustments as the chair performs so outstanding and keeps you in any position your want. If I want to sit straight it does it with felt feedback. It also molds into my unique poster so much better than the AEON line. I had the benefit testing these chairs out side by side. I feel this review lacks this aspect. Herman Miller designed this chair to be functional and automatic.

You guys deserve so many more subscribers. Excellent reviews that have been so helpful

This chair is so strange, but so special. It's hard to describe just how soft and light yet incredibly sturdy it feels to touch and to sit in. I personally think I still want an Aeron over this since I am an upright tasker and need-need-need the forward tilt support in my life for a long days' fatigue, but it's a real experience and I see why some people love it so much.

Great and thorough review! I'll check out other reviews from BTOD.

I've had my Cosm for a few months and I really like it. It's definitely a "pushy" chair in that it has decided what position is ergonomic and it kind of just makes you sit that way automatically. As a big guy the #1 improvement they could make would be a wider seat. I fit but don't have a lot of room to twist around without the sides of the seat getting in the way. This review mentioned the short seat depth, but I am just over six feet tall (1.82m) and find it very comfortable. It does drop off a little earlier than cushioned chairs but I like it because there is no pressure on the bottom of your legs at the edge. The curved mesh does a nice job of just dropping away smoothly. However if you are much taller than 6 feet you may not feel enough support under your legs from this chair. As far as the mesh on bare skin goes: literally no problems for me and this was one of my biggest concerns going with a mesh chair. I ordered fabric samples from Herman Miller in advance. They call this their "Intercept" fabric and it is much smoother than the "Rhythm" or "Balance" fabrics they offer on other chairs, which felt like sandpaper in comparison. Supporting the fact that mesh is polarizing, I am now convinced that mesh is the only choice for a chair needed for long sitting sessions. It is so nice and cool. You will never stick to it like a leather chair but it is so much easier to clean than the old school fabric-over-foam design (you can just wipe it down with a damp cloth). Disagreeing with this review, I have found it very nice working long shifts in this chair since it encourages good posture. You won't be folding your leg to sit with your ankle under your other knee the way I used to in my old cushioned office chair. This can feel like a limitation. It's better than the back pain I was getting before, but it makes me long for a plush gaming recliner while watching long videos where I want to lounge back and don't need the keyboard/mouse. It took a little bit but the key to enjoying the leaf arms was having my keyboard and mouse at the right height. I've found that the leaf arms keep my shoulders back instead of hunched forward, and I don't really feel the solid plastic frame around the front of the armrest since my arm is a little bit above it. I actually like that there is zero adjustability to the arms. Maybe I am crazy but I cannot stand when adjustable arms have a half millimeter of play so they move around and make noise. I prefer the solid feel of these leaf armrests. Herman Miller doesn't make them an option on the chair but they do sell larger wheels that are easily swapped in. I ordered these but it was a waste. The smaller wheels actually roll better on my solid wood floor. Since I am not rolling over any bumps or transitions or carpet, I don't get the benefit of the larger wheels.

Best chair (and furniture) review website ever! I've watched many of your reviews and then bought this cosm chair. It is very comfortable to sit on. IMO, it is a huge improvement over Aeron and Mirra 2, whose sharp edge cuts into the thighs. (I skipped Embody because I want a mesh chair and Embody is twice more expensive.) But, I am experiencing an annoying "noise" problem. When I sit down on the chair, the whole chair sinks a little bit (not the mesh) in the central pillar, which is probably part of the weight-sensing mechanism, the spring makes a small noise, which is ok. BUT, when I stand up, the whole chair pops back suddenly and makes a big noise when hitting the end. No one has brought it up. Hasn't anybody else noticed it? Is it just me?

Thanks a lot for a detailed review

Could someone give me a max back height you can have without having your upper back pushed forward because of the seat? TIA

ever since i started working in 2014, ive been having pains in my lower back. but when i go to the chiropractor i wasnt in pain cuz it only hurts when im working in the office. i would like to invest in a really good chair that can support the lower back, arms and neck..

I'm between the low back Cosm and the Setu.

With the unified component design, it will be impossible to replace some parts in the future compared to a mirra and aeron

Good review. I've been using the Cosm for 4 months now for long working days at a desk. I came from a medium size Aeron and I'm 195cm. Mine is a Medium height back (which is much higher than most office chairs) in Canyon red with a grey mesh. It's a great looking chair - elegant and lightweight and a real contrast the morass of black and grey chairs and doesn't look out of place in a home environment I really like mesh seats - they're much cooler to sit in. I had my Aeron for over 10 years and while I still think it's one of the most comfortable chairs I've sat in, after long days I'd feel the hard edges and sides of the seat - and the hard edge at the top of the back rest. The Cosm solves all those issues - I don't find the seat too short, and despite my height the medium backrest gives comfortable support high enough up my back. There are no hard edges and the flexibility of the back frame means it's also comfortable when leaning or reaching for things. What really surprises me is the level of comfortable lumbar support the chair gives. I was expecting this to be a weakness looking at the design but I've never experienced any back pain and there's none of the 'hard push' that other chair's lumbar supports give (neither of the older Aeron designs worked that well) Likewise the lack of adjustment - i really think the Cosm delivers on the designers promise and 'just works'. the seat tension auto adjust is perfect - if you want to lean back more you just lower the seat slightly. To sit more upright make the seat a little higher. It's intuitive and natural (and of course, as intended, it means multiple people can use the chair and be comfortable without needing to make a load of adjustments). If there's one thing thats turned out to be a disappointment it's the Leaf arms. They look amazing and I found on the phone or a video call when you're sat back they were really comfortable. However, over time I discovered were just slightly too high when typing and lifted my shoulder leading to pain later. I've now removed them and am just using the chair without. To be honest I've never found arms that worked on any office chair I've used - if they were high enough to rest on they got in the way at other times so I've always just dropped them low and not used them. Before I bought the Cosm I was looking at a new Aeron without arms fitted. As per the review I think the leaf ams would be great in a conference setting and I'm pretty sure I wouldn't get on with either of the other Cosm arm designs.

For ppl who have got the "High-back" version, is it suitable also for comfortable watching movies sometimes with 1-2 legs on the desk??? THX.

hello, which has a better seat comfort? The aeron or the Cosm? what could be the difference in regards to seat comfort? Thank you.

i just got my cosm a few days ago and i love it! thank you guys, i watched through a ton of your videos before i came to find a chair of my own

Has anyone who owns it also had lower back pain from the stiffness of the lumbar support? I’ve seen a few people saying the same and want to find out what people have done about it, or if they’ve just returned it

Thanks for the review! Any chance you guys will check out the Herman Miller Sayl chair?

I a looking for a real good office chair that has good thoracic support and the ability for the arms to come totally up. I mean out of the way. I play guitar that is why. Any help would be greatly appreciated!

How tall is the lady in your video? I’m thinking of getting the high back version so I can use the headrest, but I’m not sure if 5’4” is too short for it.

BTOD.COM IS WHAT RTINGS.COM IS FOR TVS

Great video.

What would you guys recommend for this chair, Fixed or adjustable arms?

I've tried the Aeron, Mirra 2, Embody and Gesture for extended periods of time each and this Cosm with Leaf arms is hands down the best of the bunch. The arms do rub your elbows raw for a few days but they soften up a lot after that and the irritation goes away. I find I like the leaf arms now more than any other chairs arms.

Fantastic review!

For your averages, how many people are in your office and what are their common body sizes?

its basically the perfect fancy dining chair if you remove the rollers maybe. :D seriously i consider these for that. super expensive for that but imagine a modern dining table with a few of these and not rollers.

The Herman Miller Cosm High Back was the most comfortable office chair I've ever had the pleasure of sitting in. Yes, even moreso than the Aeron in my case. I'm 5'10 and it fit the shape of my body perfectly! Though I must mention that the one I sat in had the leaf arm rests and I hated them with a passion. They're definitely not good for desk work. I recommend the height adjustable armrests all day for their functionality and comfort to adapt to your usage situation. Hope I can buy one in the future someday but unfortunately the price is unjustifiable for me right now.

It’s amazing

i got cosm leaf arm for 2 weeked, for me it too short seat dimention but i very love about not adjustment and back support , like you said leaf arm is poor but think to change to adjust-arm than leaf arm

I sat on it and it’s seat was big for me ...the seat is one size? and for some reason I found the Aaron seat more comfortable

What are people's thoughts on the lowest-back option of the Cosm, anyone love it or hate it?

The Cosm with adjustable arms is hard to beat...I am still contemplating going with it over my Embody Gaming Chair.

I went to a HM distributor they had the cosm there. I wasn't even there to test it, but it was actually very good,. The embody felt too hard on my back. The cosm was actually very comfortable.

My Cosm has started to give a squeak sound when I sit on it. How can I lubricate it? Cannot find any instructions

What I didn't like about Cosm chair is that there is a "hard stop with noise" when the recline reaches the end (I don't know any reviews that picked up that), which is annoying and does not happen on Embody and Aeron (more dampened and soft). Other than that the overall comfort feels the same as Embody, maybe a little less, however Embody offers much better adjustments so I ended up with Embody.

A chair for tall people. FINALLY!!!

Have y’all tried the NBF Raleigh High Back Mesh Chair?

What if it starts squeaking? Will that be covered by the warranty?

What's your top rated ergonomic chair 2019? Thank you.

Is it suspicious to anyone else that this is the only Cosm video review on the internet?

Debating between Embody or Cosm because I'm 6f 4 and worried that the back of the embody might be too short since it has no headrest.Want the chair primarily for gaming so comfort and back support are very important anybody tried both chairs for comparison?

Is it possible to order it without the armrests of any kind?

Guys: I have heard a lot about people having their back being pushed forward (their upper back to be more accurate) as a cause of the way the chairs backseat is formed. Could you give me a max. back height you are allowed to have without being automatically pushed forward by the backrest? Btw: I am 1.75 and a rather small build. (also very low weight) Would this Chair fit me?

What is the recommendation of the backrest height for a person 5'3" tall. Is a tall back going to be less comfortable then a mid size back. Is the tall back more for a tall person?

What chair has the highest comfort score? Also which chair has the broadest appeal?

Most confusing part about this review is that he says the chair forces you to lean back, while other reviewers have specifically said the opposite (that’s it’s really hard to lean back on it, and the chair back pushes you forward to sit upright). Very confusing how two reviewers can have an opposite experience from this… Any views on why that’s the case? I would definitely like to lean back without having to work for it.

This is the most comfortable desk chair I have ever sat on

Does the front of the seat give pressure on the thighs like Aeron?

Are the leaf arms removable after receiving the chair?

no it doesn't want to tilt you back slightly. on the contrary. at least for my 67ish kg weight

You didn't mention the noisy mechanism that clatters when you sit or move around on the chair 😞

god i wish that were me

To be honest, looks like it would be perfect for gaming, particularly console gaming.

I went with the Mirra 2, much better chair.

I'm 6'2" ... to tall for the high-back to function as a real head-rest, I think :/ Alteast in the images I see, the tall people always end up poking their head over the head-rest ... neck rest, more like. otherwise I'd love this one, but I need something to rest my head on, when leaning back. Why is Herman Miller so allergic to proper headrests? They explicitly made a point of talking about their Embody 'gaming' chair not having one... I know the Aeron has a bunch of 3rd-party aftermarket headrests, but I'm not sure how I feel about mounting something 3rd party to a chair this expensive.

Alright abrasive mesh I’m out. At least on the leaf arms. Sad since they looks so cool but I know myself

thats the 'coolest' looking chair ive seen

If you're above 6'2 or somewhat tall but slightly bigger in the thigh area, don't buy this chair, after researching for a long time I bought one (for ref. I'm 6'2 250lbs/190cm 115kg, pretty muscular with some bodyfat) and the frame was pressing so hard against my thighs that I couldn't sit in it for any reasonable amount of time and had some slight bruising afterwards. If you don't have my bodytype though, by all means go for it, the chair really does lock you in to a very ergonomic position and feels amazing, even the armrests didn't bother me at all while wearing a t-shirt, honestly really sad that they don't make these in three sizes like the aerons, that would have probably made the difference.

Call center aint no money for a herman miler!

All I worry is that my cat using this as a scratch post. Yikes

Cos.. or some say Cosm....

Form follows function. I do not appreciate trolling. I have been using and testing high-end work chairs for decades, both out of necessity and as a hobby. In my experience, the Herman Miller Cosm chair stands out as the least suitable high-end seating option. When considering the principle of form following function, this chair represents the worst example of it. I simply do not have space for decorative pieces better suited for lesser-known museums.

The weird forward-leaning "leaf" armrests destroy my upper back and shoulders

So silly that for such an enormous price you can't even control the tilt.

If you are 6ft2 and weigh 270lbs, chair is too small. Believe me

Took delivery of an Aeron recently. Disappointed in the product. Disgusted with customer service.

Such an expensive chair but very little adjustments, what a shame.

to put long story short - this is AWFUL design. And NO it has nothing really good going for it. It's a monument for complete design failure! Calling this "high end" is absurd. To put it mildly.

HM shamelessly copied the design philosophy of Humanscale Freedom, and 20 years later.

Poor chair design by Herman Miller.
