How old are the chairs, what is their expected life, and will parts still be available in 10 years?

A-dec chairs are designed and manufactured to have a 20-year service life if they are properly maintained and serviced.

We only source chairs we know the service history of. Many of the chairs we have installed and serviced for their whole life. Chairs are generally 10 to 11 years old, replaced as part of an asset renewal program. Our refurbishment process is designed to ensure a further 10 years of service life.

Key parts that are no longer supplied by A-dec are replaced with new parts. For example, we replace older electric motors with the latest A-dec XC-10 motor kits, to ensures can be fully maintained for their life.
