How do you clean an A-dec dental chair?
A-dec recommends cleaning the upholstery using a solution of mild, non-ionic detergent and water, or commercially available cleaners containing no alcohol, bleach, or ammonia. Get more information in the A-dec Upholstery Maintenance Guide.

How long should a dental chair last?
With proper maintenance and service, A-dec dental chairs are designed and tested for a “service life” of 20 years under normal use. The actual service life can be influenced by factors such as environment, extent of use, cleaning and maintenance frequency, and preventative maintenance of normal service “wear & tear” components. Please review A-dec’s customer warranty for complete details, including applicable disclaimers and limitations of liability.

What is the warranty for an A-dec dental chair?
A-dec is pleased to offer a 5-year warranty for all dental equipment and furniture purchased from an authorised A-dec dealer. See A-dec, Inc. Express Limited Warranty for full warranty information.
