Massage chairs are worth the high prices you will probably need to pay for them if you are constantly having to go to a chiropractor or other places to get yourself a body massage, that helps you to deal with the pains and aches that you have.
A body massage chair can be good for people who have chronic leg and back pain as spending some time on them can make you feel better. Some chairs can even give you a decent neck and shoulder massage that can be very invigorating after a stressful day at the office, where you have spent hours hunched over a desk. But this will not be anywhere near the relief that a visit to the chiropractor will bring you.
What it does bring you, however, is the convenience of having a massage that can be both soothing and therapeutic in the comfort of your home.
