Herman Miller - Equa chair

Since the 1980s the Equa chair has been a benchmark for ergonomic seating. Breaking with the tradition of regarding a seat as a token for the sitter’s status, Equa concentrates instead on a equal degree of comfort throughout the office.

Features and benefits

• The Equa 2 chair features the patented Equa shell, a single piece of fibreglass-reinforced polyester resin designed for dynamic sitting.
• An H-shaped cut-out lets the back and seat flex separately, so the chair moves naturally with the user and provides good lower back support for every work posture. The H-shaped cut-out also lets air circulate, preventing heat build-up during long-term sitting.
• The shell is manufactured in an environmentally safe way, with integral colour and durable materials for a long, hard-working life.
• To fit a broad range of people, the Equa 2 work chair comes in three shell sizes - A, B, and C, so everyone, from smaller and lighter to taller and heavier men and women, can have uncompromised comfort and support.
• An optional tilt-lock feature secures the work chair in an upright position for work-intensive postures. Equa 2 stools, unlike most stools, also have a tilt option.
• People can easily adjust the arms of the Equa 2 chair to suit their size and activity. Optionally, the arm adjusts vertically in a 10cm range and laterally up to 2cm.
• The pneumatic adjustment provides generous seat height ranges to accommodate shorter and taller workers - and everyone in between.
• The Equa 2 chair’s armrests pivot up to 25 degrees to give computer users comfortable and healthful forearm support while keyboarding and mousing.
• A warm, slightly textured finish on the aluminium base and frame doesn’t show scuffs and scrapes, and adds an understated touch of elegance that blends with a range of office interiors.

Design story

The Equa 2 chair was designed by Bill Stumpf and Don Chadwick to give everyone - regardless of status, work style, or physical shape - the comfort and support that only come with superior ergonomic design.

Offered in three sizes, the Equa 2 chair accommodates the wide variety of people in today’s diverse working population. While most office chairs are designed only for 'average-sized' people, the Equa 2 chair gives men and women - whether they’re average or not - an exact fit.

The distinctive design of the original Equa models is preserved and refreshed in the Equa 2 chair. The trademark contours and softly rounded edges form a clean-cut, flowing profile.

A warm, slightly textured finish on the aluminium base and frame adds an understated touch of elegance-and doesn’t show scuffs and scrapes. This refined Equa 2 look blends with all kinds of office environments.

Enriched ergonomics provide any user with healthful comfort. The adjustable lumbar support, extensive seat-height range, and fully adjustable arms let the Equa 2 chair give equal support for every working posture.

Whether it’s long hours at the VDT, a quick phone conversation, or a casual staff meeting, the Equa 2 chair adapts, delivering consistently exceptional performance. Its adjustments, combined with a shell that flexes responsively, make all positions natural in the Equa 2 chair.

The processes and materials used in the manufacture of the Equa 2 chair support Herman Miller’s commitment to preserving the environment. They also make possible the look that has distinguished the Equa chair since it was first introduced. Now, with a freshened yet kindred appearance, the Equa 2 chair blends well with existing Equa seating.
