I work in a big company and we have a massage chair in one of our offices. I asked our administrator about the model and she said it is Nirvana. I've heard about this brand before, but didn't know how much does it cost. It has a lot of functions, very comfortable and looks nice. But I'm not sure it is for home usage, it costs toooo much https://www.amazon.co.uk/Nirvana%C2%AE-3D-M...l/dp/B06XZBPD9P.
As for our chair, we bought an office chair with massage functions because we need both. At first I was a bit skeptical, but now I'm completely satisfied. It arrived almost assembled, so I put it down and it's done. Not very big, but just right for our bedroom. This unit doesn't smell like chemicals and is of good quality and have a really great country house look. Besides, I like the fact that it has a remote control.
For an old lady two these options are not right, I suppose...
