I would definitely have the person who will be using it try it out to be sure s/he REALLY likes it. They are all pretty big and take up a significant amount of floor space and some folks like it a lot more than others.
My siblings have different models of massage chairs and they get varying amounts of use from the residents of the house and visitors. Personally, I’m not a fan, but have tried various massage chairs.
Other things that are less expensive and have a smaller “footprint” are Nekttech massager that massages the back & neck (under $50) and arm and leg devices that squeeze and release pressure (sort of like a blood pressure cuff or what they use in the hospital to prevent blood clots. We have these things and they get varying amounts of use, which is OK since they don’t take up that much space.
