Finding the right office chair is a priority for anyone who sits for extended periods. When you dedicate significant portions of your day to being seated, comfort and support aren’t just luxuries but necessities.

The Herman Miller brand, well-regarded for its commitment to ergonomic design, has often been at the forefront of many discussions about office furniture. Naturally, my interest was piqued when I came across their Cosm Chair in Australia, so I went and tried it out in the Living Edge store in Richmond (I'm based in Melbourne).

The chair's sleek design is immediately striking, but there's so much more to the office chair than appearance. In this review, I will explore its features, evaluate its comfort and build quality, touch on its aesthetics, and critically assess its value for money based on my experience. Let’s dive deep.

Herman Miller Cosm: At a Glance

I was impressed by my experience with the Herman Miller Cosm Chair. Its innovative design and ergonomic features show that the chair was crafted to provide an unmatched seating journey. What first stood out to me was the "Auto-Harmonic Tilt" technology, a unique feature that allowed the chair to adapt to my posture and movements automatically. This ensured that I was always comfortable without fumbling with manual adjustments.

Likewise, the suspension system of the Cosm Chair used a flexible and supportive system that conformed to the contours of my body. It felt lightweight and breathable, which makes a huge difference during long work hours.

There are options for high-back and mid-back designs, various armrest styles, and various finishes and colours. I tried the mid-back design with adjustable armrests. I'll discuss the differences below. The chair comes fully assembled and has a 12-year warranty.

Although Herman Miller Cosm's automated features are impressive, it did require a bit of a learning curve to adapt to the automation fully—there were moments when I found myself wanting to make manual adjustments. Likewise, I tested its leaf armrests at the living edge showroom, and they were slightly uncomfortable to use. You also get no headrest.

Best Bits of Herman Miller Cosm Chair

Having personally experienced the Herman Miller Cosm Chair, I can attest to its numerous remarkable features that have led to its widespread popularity among professionals who crave comfort and support during extended work hours. Here is what stood out for me:

1. Build Quality

The Herman Miller Cosm does not lack in quality and exceptional craftsmanship. Kudos to Studio 7.5 for its impeccable design. The materials, ranging from polyamide to polypropylene, ensure flexibility and durability. The highlight for me is the continuous mesh from the backrest to the seat—no irritating gap.

The mesh fabric used in the chair's backrest is comfortable and resistant to wear and tear. It is made from a combination of polyester and elastomeric. The chair's components are also manufactured to exacting standards, ensuring a reliable and long-lasting product.

2. Auto-Harmonic Tilt

One feature that truly resonated with me was the Auto-Harmonic Tilt. The first time I adjusted myself in the chair, I felt it intuitively moving with me. This innovative mechanism dynamically responds to my body's subtle shifts and movements.

Rather than having to fidget and readjust continually, the chair naturally ensures I'm balanced and supported, irrespective of the position I find myself in. But it isn't just about the tilt mechanism. The combination of its flexible frame, the intercept suspension, and the breathable mesh back all contribute to a seating experience that feels almost tailor-made.

💡
Expert note:

Unlike other chairs with automatic tilts, which often make the body adapt to the tilt, Cosm's approach is more intuitive. It intelligently gauges the downward force I apply and adjusts the tension accordingly. This ensures a consistent and comfortable experience that caters to any body type regardless of how you are sitting.

3. Ergonomics & Aesthetics

You start to appreciate the tiny details when you've sat in as many as I have. Besides its automatic tilt mechanism, two other standout features of the Herman Miller Cosm I appreciated were the armrests and the unique approach to the backrest. Both of which are crucial to ergonomics. I'll review them below and help you choose which is ideal on both fronts.

But besides the two, the Cosm chair features a range of advanced ergonomic functionalities, including a flexible frame and suspension technology that seamlessly adjusts to your body, a continuous support backrest that adapts to movement, lumbar support and an optional PostureFit feature for additional lower back support, and quiet roll casters for smooth and noiseless movement, complementing the overall user-friendly design of the office chair.

For aesthetics, Herman Miller Cosm is certainly eye-catching. Its engineering is evident in its distinct curves. The chair offers a range of colours, including graphite, carbon, studio white, nightfall, canyon, and glacier. While these shades lean towards a more sophisticated palette, potential buyers might want to see and judge whether these hues match their sense of style.

4. Elastomeric Backrest & Varying Sizes

Experiencing the Cosm chair with the Intercept Suspension was also truly intriguing—likewise, the use of elastomeric materials in its design. The backrest is crafted from elastomeric polyester mesh that offers a remarkable ability to adapt to my body contours as I settle in. The mesh was also breathable, facilitating a comfortable seating experience and proper airflow.

But it doesn't end here. Whether you're tall, short, or fall somewhere in between, Herman Miller Cosm offers diverse sizes and shapes. From Low-Back to Mid-Back and even High-Back options. Here's a little insight into which type might be just right for you:

  1. The low backrest is perfect if you prioritise an open and airy feel or often move around while seated and want more freedom of movement for your upper body. I recommend them for tasks that involve leaning forward or requiring frequent changes in posture, such as active discussions, quick meetings, or tasks that involve reaching across a table.
  2. The mid-backrest option for its balance between support and mobility, offering upper back support without restricting movement. Ideal for engaging in a mix of tasks that involve both leaning back for support and leaning forward for focused work.
  3. Choose the high backrest if you seek comprehensive upper back support, especially during extended periods of seated work. Likewise, a high backrest is ideal if your job requires sustained focus and concentration, such as long hours of computer work or tasks involving reading, writing, or analyzing documents.
💡
Expert advice:

Choose a low backrest for quick tasks; mid or high options are more suitable for extended work sessions. If dealing with back or neck concerns, consider mid/high backrests. When aiming to foster collaboration, a low backrest is appropriate, whereas mid/high options are conducive to maintaining focus.

5. Innovative Suspension Leaf Armrest

The armrests of the Cosm chair are also designed with ergonomics in mind, with four variants to choose from. There is the novel leaf arm or suspension leaf, the fixed armrest, no arms, and the height-adjustable armrest. The material covering the armrests is the same breathable mesh found on the backrest. Here's how to decide which to choose:

  1. Fixed armrests are ideal if you prefer a simple and streamlined design and don't require frequent adjustments. Likewise, the fixed armrests are suitable if you have a consistent sitting position and don't need to change the armrest height or angle frequently.
  2. Choose height-adjustable armrests if you want some level of customisation and need to adjust the height of their armrests. I opted for them as they allow me to switch between different tasks. Plus, I share the chair with my partner, who I'm slightly taller than, so adjustments come in handy.
  3. No Armrests are ideal if you prefer an open and unrestricted seating experience. For activities with a wide range of movement where arm support may get in the way such as playing musical instruments.
  4. The Leaf Arms have a soft but firm cradle design that is supposed to provide a large, cosy resting place for your elbows, but my experience was different.

6. Comfort

Comfort is crucial when choosing an office chair, and the Herman Miller Cosm Chair excels considerably. The chair's ergonomic design and advanced tilt mechanism allow for effortless reclining and encourage natural body movements.

I particularly appreciate the breathable mesh backrest, which ensures a constant airflow that prevents any discomfort caused by heat buildup. The chair provides comprehensive coverage from your thighs to your upper back, ensuring a comfortable experience.

7. Price and Value for Money

Now, let’s address the elephant in the room: the price tag. Undoubtedly, the Herman Miller Cosm Chair comes with a premium price tag, which may give some potential buyers pause. However, it's crucial to consider its value in terms of comfort, durability, and long-term health benefits.

While the initial investment might seem steep, the chair's quality and performance make it a worthwhile choice for those who prioritise their well-being and spend significant time sitting.

8. Warranty & Return Policy

The Herman Miller Cosm comes with an impressive 12-year warranty. Any replacement parts covered by the warranty will be shipped free of charge, and repairs are made by a Herman Miller expert close to you. The warranty also covers the chair as a whole, as stated on the manufacturer's warranty page, "Our warranty covers everything – including electrical components, casters, pneumatic cylinders, tilts, and all moving mechanisms."

Depending on your vendor, you may also get a return policy. And if your vendor offers a return policy, the duration may differ from others.

Drawbacks of the Herman Miller Cosm Chair

Drawbacks of the Herman Miller Cosm Chair

While the Herman Miller Cosm is an excellent chair in ergonomics, comfortability, functionality, and Aesthetics, there are some drawbacks.

1. Lack of Headrest

One ergonomic piece missing in the Herman Miller Cosm is a headrest, which I find a concern. When you look at other high-end chairs, a headrest is usually a part of the package.

2. Armrests Could be Uncomfortable

This is not a problem if you chose the adjustable armrest, but the leaf armrest? It felt a bit awkward when I sat in it. The armrest put my elbow and forearm in an unnatural position that became uncomfortable in no time.

3. No Adjustment Knob

For the control freaks, the Herman Miller Cosm is a big no. The automatic adjustment offered by the chair is very innovative and exotic, but it can be frustrating in some regards. Sometimes, I tried reaching out for a knob to adjust my position slightly, but it was not there. Finding the best sitting position for yourself will take some time, especially if you're used to turning knobs.

4. Pricey

Yeah, the price is a big statement. An office chair budget over $2,500 is far from modest for many. You may argue that the features and functionalities are commensurate with the price.

It combines convenience and active sitting in one chair. It features a foam-padded side for normal sitting convenience, while the other has a fit-ball for active seating.

The padded side offers comfortable seating for extended hours while the active surface encourages improved posture, blood flow, and core strength. One significant shortfall of the ErgoFlip Deluxe is that it may take some time to get used to the active surface.

So, Is the Herman Miller Cosm Worth It?

The Herman Miller Cosm Chair has an innovative, ergonomic design, coupled with outstanding build quality, that makes it an investment worth considering if you prioritise comfort and support during long work hours.
