Choose Your Engineered Now Headrest

All Engineered Now headrests are designed specifically for the Herman Miller Aeron and built to the same engineering and durability standards, including a 12-year warranty.

The difference between models is not quality — it is how the headrest behaves and who it is best suited for.

What All Engineered Now Headrests Share

Superior Ergonomics

Designed to support healthy head and neck posture across a wide range of working and reclining positions, helping reduce strain during long sitting sessions.

Designed for the Aeron

Each headrest is engineered to complement the Aeron in materials, mesh, color, and overall design — visually and functionally.

Fully Adjustable

All models allow adjustment of height, depth, and tilt of the head support, enabling precise positioning based on posture and preference.

Simple Installation

Arrives with everything needed. Installation is straightforward and well documented.

12-Year Warranty

All Engineered Now headrests are backed by a 12-year warranty covering materials, functionality, and moving mechanisms under normal use.

 H6 Headrest

Fixed Support · Maximum Adjustability · Newest Generation
The H6 is the newest Engineered Now headrest and is designed for users who want precise adjustment combined with a stable, fixed feel.

Why customers choose H6

Highly adjustable in three dimensions

 Height, depth, and tilt can be finely adjusted to position the head support exactly where you want it.

Stays firmly in place

Once adjusted, the H6 is designed to remain stable rather than moving freely with your posture. Ideal if you want consistent, repeatable support.

Tool-free adjustments

All adjustments can be made without tools. Adjustment is done while standing.

One model for a wide range of user heights

The H6 is designed to accommodate users of different heights without needing separate size variants.

Wide support surface ideal for headphones and gaming

The H6 shares the same wide support surface as the H4, making it suitable for wearing headphones, gaming, and long video calls without interference.

H3 / H4 Headrests

Free-Flow Support · Proven Design
The H3 and H4 are built around a free-flow support concept, allowing the headrest to move naturally with you as you recline and shift posture.

Why customers choose H3 / H4

Free-flow movement

After adjustment, the headrest is designed to move dynamically with your posture rather than staying fixed in one position.

Two size options based on user height

  • H3 - standard size, recommended for users under 5'11" (180 cm)
  • H4 - wider version, recommended for users 5'11" and taller

Adjustable in height, depth, and tilt

Like the H6, H3/H4 allow full adjustment of head support position — with a different movement behavior after adjustment.

Proven over time

H3/H4 have been in the market for over a decade and sold over 200,000 units. It is trusted by a large global user base.

Wide support for gaming (H4)

The H4 offers wide support and is fit for gamers and users who wear headphones, while maintaining the free-flow movement philosophy.

Final Guidance

If you prefer a headrest that you can finely adjust and rely on to stay exactly where you set it, the H6 is the right choice. It offers maximum adjustability, a wide support surface, and stable positioning — making it particularly well suited for users who wear headphones, game, or want a more fixed feel.

If you prefer a headrest that moves naturally with your posture, the H3 and H4 deliver a free-flow experience refined over more than a decade. Choose H3 or H4 based on your height, with the H4 offering wide support and a strong fit for gamers while maintaining the dynamic free-flow behavior.

All three models are engineered for long-term daily use and supported equally by Engineered Now.
