The Steelcase Karman and the Herman Miller Aeron represent the pinnacle of ergonomic office seating, but they achieve comfort through different philosophies. The Aeron from Herman Miller is an icon known for its proprietary Pellicle mesh material and three distinct sizes (A, B, C) for a tailored fit, while the Karman from Steelcase is a modern challenger offering extensive adjustability in a single size, combining a mesh back with a cushioned seat.
Here’s everything you need to know to decide which of these top-tier ergonomic chairs is right for your office.

Steelcase Karman vs. Herman Miller Aeron Comparison
Dimensions & Sizing
The most significant philosophical difference between these two chairs is their approach to sizing. The Herman Miller Aeron is famed for its three-size system (A, B, C) that caters to different body frames from petite to large. This ensures a more precise, tailored ergonomic base before any adjustments are made. You essentially choose the chassis that fits your body best, then fine-tune from there.
The Steelcase Karman takes a different approach, offering one highly adaptable frame designed to fit a vast majority of users. It relies on its extensive adjustment range - including seat depth, arm width, and lumbar height - to achieve a personalized fit. Sizing for the Aeron is prescriptive, while the Karman focuses on adjustability.
Comfort & Ergonomics
Both chairs excel in comfort, but an important distinction is what your body sits on. The Aeron's signature feature is its seat and back made from Pellicle 8Z mesh, which provides zoned pressure distribution and unmatched breathability. There are no pressure points from foam or padding - just supportive suspension. The Karman uses a breathable mesh for the back but features a more traditional foam and fabric cushion for the seat, which some users prefer for its softer initial feel.
Ergonomically, both offer top-tier lumbar support mechanisms. The Aeron’s PostureFit SL supports the sacrum and lumbar region to mimic a healthy standing posture. The Karman's support is also highly adjustable in height to target specifically where you need it most. Choosing between them often comes down to seating surface preference: all-mesh suspension vs. a mesh-back-cushioned-seat combo.
Materials & Construction
Both are built to last using premium materials, but their construction reflects their design goals. Both chairs use strong aluminum bases and frames, contributing to their durability and long life. Herman Miller’s focus is on the engineered Pellicle mesh, a material that’s both flexible and incredibly resilient.
Steelcase combines their high-quality mesh with well-crafted foam and upholstery on the seat. On sustainability, both brands are industry leaders. Herman Miller helped pioneer cradle-to-cradle design, and the Aeron is made from a significant amount of recycled material. Steelcase likewise has a strong commitment to environmental responsibility, with the Karman being lightweight and designed for end-of-life recycling.
Price & Value
There's a clear price difference. The Steelcase Karman typically starts around $900, positioning it in the premium tier but as a high-value option. In contrast, the Herman Miller Aeron starts around $1,200. This $300+ difference is significant.
The Karman's value lies in providing a massive range of adjustments and build quality that rivals the very best for less money. The Aeron’s value is tied to its iconic status, revolutionary all-mesh system, tailored sizing, and a proven track record of longevity that gives it extremely strong resale value.
Style & Versatility
Both chairs are modern, but they make different statements. The Aeron is unmistakable, a design icon that signals a dedication to both form and function. It has a high-tech, engineered aesthetic that looks at home in executive suites, tech startups, and design-forward home offices. It is a bold choice.
The Steelcase Karman has a more subtle, sleek, and minimalist appearance. Its clean lines and more conventional silhouette allow it to blend into a wider variety of office environments seamlessly without calling as much attention to itself. It offers sophistication through understatement.
Which One Should You Choose?
Both chairs are excellent investments in your comfort and health, but they serve different users and aesthetic tastes.
Choose the Steelcase Karman if:
- You prioritize fine-tuning your fit through a wide range of adjustments.
- You prefer the feel of a soft, cushioned seat combined with a breathable mesh back.
- Your budget is in the premium range, but you want to maximize value around the $900 mark.
- You want a sleek, modern chair with a less conspicuous, minimalist profile.
Choose the Herman Miller Aeron if:
- You want a chair that offers a specific, tailored fit based on your body size (A, B, or C).
- Maximum breathability is your top priority, which its all-mesh seat and back provide.
- You appreciate owning an iconic piece of modern design with lasting prestige.
- A higher budget is acceptable, and you value a strong brand reputation and resale value.
Frequently Asked Questions
What's the main difference between the Karman and Aeron?
The biggest differences are in their approach to sizing and seating surfaces. The Aeron comes in three distinct sizes (A, B, C) for a prescriptive fit and uses a proprietary mesh material for both the seat and back. The Karman comes in one highly adjustable size and uses a mesh back with a more traditional cushioned fabric seat.
Which chair is more comfortable for long hours?
Comfort is subjective, but both are designed for all-day use. If you tend to run hot or live in a warm climate, the Aeron's superior breathability from its all-mesh design is a huge advantage. If you prefer a softer initial feel, you may find the Karman's cushioned seat more comfortable than the Aeron's firm, suspended feel.
Is the Herman Miller Aeron worth the extra money?
For many, yes. You're paying for an iconic design, the research and development behind the Pellicle mesh and PostureFit SL system, a choice of three distinct sizes for a tailored fit, and excellent brand reputation and resale value. If these factors are important to you, the price premium is justifiable.
How do I know which Aeron size to get?
Herman Miller provides a height and weight chart to help you choose. Size A is for smaller users, Size C is for taller and heavier users, and Size B is the most popular, fitting the widest range of people. If possible, sitting in each size at an authorized dealer is the best way to determine your perfect fit.
Does the Steelcase Karman offer a better warranty?
Both Steelcase and Herman Miller are renowned for their industry-leading warranties. Both typically offer a 12-year warranty that covers nearly all components of the chair, underscoring their commitment to quality and durability. You're getting a long-term investment with either choice.
Can I try these chairs before buying?
Absolutely. Both Steelcase and Herman Miller have extensive networks of authorized dealers and showrooms where you can test their chairs to find the perfect fit and configuration for your needs.
Which brand is better for sustainability?
Both are considered leaders in sustainable manufacturing. Herman Miller focuses on cradle-to-cradle design principles, meaning its products are designed to be disassembled and recycled. Steelcase also heavily incorporates recycled materials into its products and prioritizes eco-friendly production processes. You can't go wrong with either from an environmental perspective.
Does the Aeron feel too firm since it's all mesh?
The Aeron's mesh provides a unique "floating" or suspension-style support rather than firmness from cushioning. The mesh conforms to your body, eliminating pressure points. Some new users find it requires a brief adjustment period compared to an old foam chair, but most come to prefer its distinct style of ergonomic support.
