The strength of the massage chair you choose will depend on your preferences for massage. Some people like a very deep massage, while others like a gentler one, and still others prefer a massage somewhere in between. If you want to have an intense massage, look for a chair with a quad roller system – in other words, there are four rollers. Ensure that it has highly protruded components as well as strong movements that require one motor per function. If you prefer a softer massage, try one with two large rollers instead of four that uses soft movements. A lot of the best massage chairs have removable padding you can add to the seat to adjust the massage strength.
