A massage chair is a chair designed for massages. It can refer to two types of products. Traditional massage chairs allow a masseur to easily access the head, shoulders, and back of a massage recipient, while robotic massage chairs use electronic vibrators and motors to provide a massage.

The first massage chair was designed in 1954 by Nobuo Fujimoto. He made various versions of the chair from scrap materials before he was entirely satisfied with the chair.

Chair Massage is done in an ergonomically designed portable chair. Chair massage focuses on the head, neck, shoulders, back, arms and hands. Massage therapists are able to offer on-site massage to many environments because of the portability of the massage chair, and clients do not need to disrobe to receive a chair massage.

A robotic massage chair contains internal electronic motors and gears designed to massage the person sitting in them. Most robotic massage chairs have some form of controller to vary the type, location, or intensity of the massage.

The benefits of a massage chair include deep relaxation, reduced blood pressure, a lowering of the pulse rate, and increased metabolism.

Today, Japan is the largest consumer of massage chairs with some surveys suggesting that over 20% of Japanese households actually own a massage chair.
