I like the chair. The heat and message were not important for me to have, but I am happy that this chair came with the options. I have lower back problems, and the heat and message features give me much needed comfort. I was able to adjust the base of the chair to change the angle in which it sits. However, I can not find any way to adjust the back tension. When the foot rest is up, the back of the chair wants to keep going back too easily. If there is some way to adjust the back tension on this model, please let me know! Otherwise, I would give this chair a 4.5 to 5 star rating.
