There are some easy steps you can take to add years to your massage chair. Just like your car, your chair has many moving parts and they can wear out over time. As well, the fabric that makes contact with the back rollers must be checked for wear and tear so that it does not cause serious damage to your device.
The Fabric
Your massage chair is more than just massage. The outer cover of your chair is likely made of multiple types of fabric, and each one has its own procedures for proper care. Leather and synthetic chairs will have inner fabrics below the surface that need to be checked for wear. If a rip occurs in the fabric that makes contact with the back-rollers, that fabric should be changed before the chair is used again. Many catastrophic massage chair failures occur when torn fabric gets caught in the gears and mechanisms of the massage chair.
The Electrical Input
Just like most other new household appliances, your massage chair is a complex electrical system with a microcontroller and small electrical components. Protecting your massage chair with a high-end surge suppressor is a good way to protect your investment. Power strips are not always surge suppressors, so you will want to research before you make a purchase. For protection against power failures while you are reclined in the chair, a high-end battery backup with surge suppression is a good option. These should be considered for anyone with mobility issues.
The Moving Parts
Like your car, your massage chair has many moving parts that need occasional maintenance. Every two to three years, a trained technician should remove the covers to inspect the belts, motors, arms and gears for unusual wear and make sure that all of the lubricants are properly protecting the parts from wear. As well, it is important not to put unnecessary pressure on the massage chair rollers. They are not designed for extreme stresses, and can break easily if they must overcome too much pressure.
