Orangebox Spira Plus chair

£629.00 (ex VAT)

The Orangebox Spira Plus task chair has the performance credentials of a specialist chair, yet still has 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, means a better fit for users.

We like the 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 user. This chair is the midback version.

The Spira Plus also features a retro-fittable headrest and 4D arms, making it suitable for a variety of tasks and applications.
