Customer Recommendation:

Amy and Lynn from Wisconsin
A+++ product and A+++ customer service (Bruce). Thank you for my patience in the many questions I had, it was worth it! This chair is magic, who needs a massage therapist, when you can personalize your own massage. Has several pre-settings for various massages and massage/airbag manipulation (I haven't even gotten through them all yet). .... Thank you again for providing excellent customer service!
