Definitely not massaging, they should really take the word “massage” out of the chair name as it’s nothing even comparable. It does vibrate and the vibration is decent strength and I do also like how you can customize where the vibration is, (i.e. just the back, just in the seat or both) and has different level settings and options. The chair itself looks very nice and is comfortable which is why I even gave it 3 stars, but it also has wires hanging from everywhere it seems. That may not bother some people,  but I was hoping for 1 chord that you could easily hide, so that it looks nice in my office.
