Bought this chair for our 99 yo mother-in-law who is now living with us after she fell and broke her hip. I think the chair is amazing and very comfortable. But it’s taking her awhile to master the position controller. It would be helpful if that could be made less confusing for an elderly person. We haven’t introduced the massageheat controller yet. I retrospect I think we could have passed on that feature and continued using her own heating pad.
