While the owner's manual is a bit difficult, it becomes clear with practice. All the new features are remarkable considering the price.  The stretch feature was new to me and I just love it. I use it at least 30 minutes a day, and the money is so worth it. I'm glad I bought it

My husband have been having back pain for years and his neck gets stiff often and massage is the only thing that works. The zero gravity position helps his lower back, the heat therapy feels great on my back and shoulders too. Some days he just sits in the chair, just for the amazing foot rollers. he love this chair and highly recommend this chair to anyone looking for a back pain relief
