OS-3D Pro Dreamer is the chair I even wanted. I was looking for a strong yet smooth massage chair, but most massage chairs either too aggressive or too weak for me and my husband. We really love this chair because we can adjust however, whenever, and wherever we want! 3D rollers give us really deep tissue massage especially when we have serious back pain. My husband, he and I both work full time, and we sit down all day long which brings a lot of stress for our backs. The chair really releases back stress and relaxes pain we have. We can even sleep better without any pain killer. It also gives us smooth and soft massage if we want to. Sometimes my hands and feet get really cold because of bad blood circulation. But, since the chair has air bags everywhere you can imagine, it really helps me to have better circulation for my body. I love foot rollers on the bottom of the feet because most of time my feet are very swollen because of heels. The chair gives me such a good pressure to get rid of all the soreness. I definitely recommend this massage chair to anybody. My husband has very wide shoulder, but it fits in the chair perfectly fine as well.
