In recent years, an increase in hybrid work has introduced greater flexibility for employees, providing on-site and remote work choices. Organizations have rapidly increased shared settings in the workplace to meet the fluctuating demands of this diverse and dynamic workforce.

Until now, this has frequently meant a compromise in seating experience. The casual light seating favored in shared settings is only intended for short duration sits. But behaviorally, on their office days, workers still tend to settle in for longer. Even if highly specified task chair is provided, very few workers take the time to make the beneficial micro adjustments, each time they settle in. Sphere has been designed to eliminate this compromise.


Soft Design

The smooth form gently wraps the body, and the entire surface of the back and seat is covered with upholstery material, creating a soft impression. The two-tone coloring also allows for a more casual space presentation.

3D Physical Fit Shell

Okamura's original "3D Physical Fit Shell" is adopted which uses an inner shell that is both supple and strong for the backrest and seat. Through unique slits, the shell naturally conforms to the physique of the user and gently wraps the body. Without the need for fine adjustment, the chair fits various physiques, including large and small people, to ensure comfortable seating. The area in contact between the chair and the body is widened, and the pressure on the body is properly dispersed. Body pressure dispersion prevents blood flow from being compressed and reduces fatigue even after sitting for long periods of time.

Responsive, Personalized Support

As each individual takes a seat, Sphere responds with natural, personalized support. No complicated adjustments are needed for fatigue-free comfort, even during lengthy working sessions.

Unique to Each Body

The back and seat naturally fit all physiques and have the necessary adjustability to enhance seating comfort, making them ideal for ABW (Activity Based Working) and free-address offices where there is no fixed location or seating.

Smooth-Fitting Arms Angled

Smooth-fitting arms angled inward are a new shape that fits today's workforce that works with all kinds of devices, including tablets and smartphones.

Comfort that Lasts

By increasing the contact area between the chair and the body, Sphere's 3D Physical Fit Shell disperses pressure. This enhances circulation and reduces fatigue, providing more comfort for longer.


Arm types and functions

Smooth fitting arms take into account the unique working posture of today's workers. Design arms rounded inward to allow for a comfortable, natural posture when working with tablets and smartphones. Gently supports elbows and arms when using devices.

4D adjustable armrest

Arms can be adjusted in four dimensions: height, depth, width, and angle-enabling the best elbow support for a range of tasks and devices.

Seat depth adjustment

Adjust the seat depth within a range of 50mm (2") by operating the levers on both sides, while seated. Option without seat depth adjustment is also available.

Reclining tension adjustment

The dial under the sat on the right side adjusts the reclining tension.

Seat height adjustment

Adjust the chair height within a range of 100mm (4'), by pulling the lever under the seat on the right.

Multi-density cushion

Okamura's Multi-density Cushion combines three layers of urethane foam, for better circulation. Soft support at the front reduces pressure on thighs while firmer hip support improves stability and posture.

Ankle-tile reclining

An ankle-tilt mechanism enables anyone to find his or her most comfortable reclining position. Using the ankle as a pivot point, this mechanism moves in sync with the seat, variation in posture and relaxation, with uninterrupted comfort.

Adjustable hanger height

The height of the hanger can be adjusted. (Stroke: 120 mm)
