Now that you simply know the advantages of massage chairs, you're probably curious about knowing who can use them. Well, massage chairs are typically designed for a mean height of 5’10”. Certain brands, like JSB offer massage chairs that automatically suits your height by sensing the highest of your shoulders when seated. If you're over 6 feet tall or suffer from knee, hip, or lower back pain then don’t buy a home massage chair that's very low to the bottom.
