Sphere ergonomic office seating

Made for activity-based working
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.

3D Physical Fit Shell that naturally conforms to the physique of the user.

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.

Re:net
Re:net is a fabric that is particularly suitable for upholstering chairs. It is made from over 80 per cent recycled materials. The fabric is knitted from threads composed of nylon from discarded fishing nets and of recycled PET.
The material with a pattern resembling a net has moderate stretch content and is soft yet structured. It is available in different colours. Depth is created by using up to four yarn colours. The fabric is durable, stain resistant and flame retardant.
