Must a work chair look like work?

While many office chairs may seem more suited to the confines of the conference room than the comforts of home, Coda is the best of both worlds—a high-performing, fully customizable office chair with a design that doesn't compromise on style.

Work smart.

We believe an office should always be organized and efficient. But what if it could inspire productivity too? Innovative features are integrated into every BDI office collection, ensuring that they work every bit as hard as you do.

Coda Collection

With two unique models to choose from, select the Coda chair that best fits your style, each with its own complementary color and base.

The Coda 3522 combines Oyster and Grey for a distinctly contemporary style, accented by its polished aluminum base.

Comfort Headrest

The wide, height-adjustable cushioned headrest locks into ten different positions across a 3.5" | 9 cm range.

Lumbar Support

Adjust placement on the spine to one of six positions, achieving the perfect balance of pressure and support.

Adjustable Armrests and Seat Depth

The armrests adjust in every direction—up/down, in/out, front/back—providing tailored alignment and ergonomic support for arms and wrists. The seat smoothly glides front and back to ensure a custom fit, no matter your height.

Synchro-Tilt & Seat Height

Easily fine-tune the feel of your chair by adjusting the amount of force needed to recline. The seat and back panel tilt in perfect harmony, keeping your legs straight while reclining.

The tilt feature locks into one of four recline positions while a gentle pull on a lever adjusts the seat to the perfect height.

Dimensions, specifications, and availability are subject to change. Shelf and drawer capacities assume even distribution of weight. Due to variations in computer monitors and mobile screens, actual colors and finishes may appear differently in person. Visit your local BDI retailer to view finish samples.



The beauty of real wood lies in the infinite variations of grain, texture, and color that develop as a tree grows. Wood is a natural product, affected by weather, climate, soil, light, and natural growth patterns.

Variations in wood patterns and colors are to be expected from one piece to the next, and will even vary from one panel to another. It is this organic characteristic of natural wood that ensures that each design is a unique work of art.

Images presented on this website are representative of the true finish, but no two screens display colors the same way. Your actual finish is likely to vary somewhat from what you observe on BDI’s website or on an actual finish sample. For the most accurate representation, please visit a BDI retailer.
