This is a sad invention. Instead of massaging, it vibrates and in no way "relieves stress". Besides this, it's very low budget: first off, the label for a "thigh massage", actually vibrates at you calves (on the ottoman). Where it is labeled "lumbar", it actually massages your thighs. When you try the pre-designed massages ("modes"), the chair vibrates very quickly at seemingly random spots. The whole thing is almost musical. Whoever designed this chair should try a different profession. Besides all this, the chair itself is fairly comfortable, and the heat is nice, although a little weak.
