Find Your Fit:
A Guide to Herman Miller Task Chairs

Few names in office seating carry the weight of Herman Miller. Known for design icons and engineering-led comfort, it’s a benchmark brand in task chairs across commercial workplaces. The only challenge is choosing the right one. This guide breaks down some of their most iconic task chairs, including Aeron, Embody, Mirra 2, Cosm, and Sayl, with a simple fit check and practical setup tips so you can specify with confidence.

The Perfect Fit Method

A good task chair supports work. A great task chair supports work and movement.

These are the non-negotiable basics:

  • Seat height that lets feet sit flat, and knees land around 90 degrees.

  • Seat depth that supports the thighs without digging into the back of the knees.

  • Back support that meets your lower back where you actually need it.

Support is how the chair behaves when you work:

  • Does the back support feel firm or forgiving?

  • Can you recline and still feel “held”?

  • Do the armrests help your shoulders relax during keyboard and mouse work?

This is where most buying guides miss the point.

  • The chair should make it easy to change posture often.

  • Recline should be usable, not a feature you never touch.

  • If you are using sit-stand, the goal is not “stand more”; it’s “move more.”

Before you choose a chair, do this 60-second fit check

Use these questions to quickly narrow your options.

  1. How long are you seated most days?
    Short bursts, mixed days, or long focus blocks.

  2. Do you run hot?
    If you overheat easily, breathability becomes a comfort feature you notice every hour.

  3. Do you move a lot while you work?
    Some people perch and shift constantly, others lock into one position.

  4. Do you like lots of adjustments or simplicity?
    More controls can be brilliant, or they can be ignored. Choose honestly.

  5. Is the chair shared or assigned?
    Shared chairs benefit from intuitive adjustment and fast “reset” ergonomics.

Set-up matters more than brand: a 5-minute chair tune-up

Whichever chair you choose, setup is what converts “nice chair” into “my chair.”

Use this simple sequence:

Set seat height

Sit back in the chair. Feet flat. If your heels lift, lower the seat.

Bring lumbar support to you

Your lower back should feel supported in the small of the back, not pushed forward aggressively. If your chair has an adjustable lumbar support, adjust it until it naturally “meets” you.

Use recline on purpose

A slight recline can reduce sustained loading. Look for a recline you can actually use, with tension that supports you rather than letting you drop back.

Set the armrests to relax the shoulders

Armrests should support the forearms lightly without lifting the shoulders or forcing elbows wide.

Check screen and input basics

If your monitor is too low, you will crane your neck. If your keyboard is too high, your shoulders will tell you first.

Herman Miller Task Chairs Explained

Each Herman Miller task chair has a distinct feel, adjustment style, and visual footprint. Use the summaries below to match features to your working style, then click through to customise finishes and request pricing through Brands by POS.

Aeron Task Chair

Aeron is the benchmark mesh task chair for a reason: it delivers structured support without heat build-up. The signature Pellicle suspension is breathable and responsive, so you get a “floating” feel with consistent tension rather than foam compression over time. Aeron is also available in multiple sizes, which makes it easier to specify the right fit across a team.

The back support system is designed to stabilise the lower spine and encourage an upright working posture, while the recline controls let you fine-tune how freely the chair moves. It’s a strong choice for users who like a confident, supportive sitting position and want a chair that stays comfortable through long, focused sessions.

Embody Task Chair

Embody Task Chair

Embody is built around dynamic, full-back support with a more cushioned feel than a classic mesh chair. Its backrest is engineered to flex and adapt as you move, supporting posture changes rather than forcing you into one position. The seat and back use a pressure-distributing support matrix intended to keep weight evenly balanced, which can reduce the “hot spots” you feel during long desk time.

Embody also offers detailed adjustment, allowing users to dial in back tension and recline for a more personalised feel. If you want a chair that feels supportive yet forgiving and value a premium, tailored sitting experience, Embody is the standout.

Mirra 2 Task Chair

Mirra 2 is the agile, high-performance option for people who frequently change posture. It’s designed to feel fast and responsive, with a backrest that flexes with movement and a tilt action that encourages active sitting. Mirra 2 can be specified with different back styles, allowing you to choose a crisper, more durable feel or a softer, more “woven” support depending on the environment and user preference.

The overall design is lighter and more athletic than bulkier executive chairs, making it ideal for modern, collaborative workplaces. If you want a chair that keeps up with a high-energy work style and still delivers serious performance, Mirra 2 is a great fit.

Cosm Task Chair

Cosm Task Chair

Cosm is all about simplicity and immediate comfort. Instead of lots of levers and dials, it’s designed to adapt automatically, giving balanced support as soon as you sit down. That makes it particularly effective in shared settings like touchdown spaces, meeting rooms, and open-plan environments where chairs are used by multiple people throughout the day.

Cosm’s continuous suspension design creates a smooth transition from seat to back, helping the chair feel supportive across a wide range of body types. If you want a refined chair that looks clean, feels premium, and works well without constant adjustment, Cosm is the “just works” option.

Sayl Task Chair

Sayl delivers ergonomic performance in a lighter, more architectural silhouette. Its distinctive back design uses varying levels of support, allowing freedom of movement while still providing structure where it matters. The result is a chair that feels open and flexible, yet supportive, and it works particularly well in spaces where aesthetics matter as much as function.

Sayl is also a strong specification choice when you want performance without visual heaviness, making it suitable for client-facing offices, studios, and compact work areas. If you want a chair that blends standout design with everyday practicality, Sayl is an excellent all-rounder.

Sayl Task Chair

No task chair is a silver bullet. The biggest gains come from pairing the right product with the right routine. A well-specified chair keeps you supported and comfortable, but the real difference comes from variety: small posture shifts, short resets, and a workspace that makes movement easy.

That’s why we treat seating as part of a bigger set-up: the chair, desk height, screen position, and how people actually work day to day. Get those elements working together, and you do not just reduce niggles, you improve energy, focus, and how the office feels to use.
