First of all it was an easy assemble. I do have a few issues with it. I am 5'11 inches and the foot rest does not extend that far I feel like my knees are up too high and that's in 0 gravity mode. Second, the shoulder air bags barely touches my shoulder so I barely feel the pressure. Lastly, the rolling balls for my neck is spaced too far out I cannot feel any squeezing to my neck. Overall I do not get a strong massage like I get from the massage chairs that are in the shopping malls. I guess I get what I paid for.
