Spira Plus Highback Ergonomic Chair
The Spira Plus task chair combines the performance credentials of a specialist chair with an aesthetic appeal that makes it suitable for large-scale preventative use.
Highly adjustable arms, headrest and back support, including integrated air cells in the lumbar and pelvic area, guarantee a better fit for users. With a contoured back shape offering snugger support, and a smaller seat option for shorter users, the Spira Plus provides ergonomic support for all.
With two back sizes and two seat sizes, the range enables accurate set-up and fit-for-purpose seating solutions for all shapes and sizes of users.
The chair also features a retrofittable headrest and 4D arms, making it suitable for a variety of tasks and applications.
