This massage chair uses a unique frame construction, a clever combination of hardwood, plywood and iron frame. The use of hardwood and plywood gives the massage chair a natural texture and a certain flexibility, making it more approachable in appearance, but also able to withstand the pressure of daily use to a certain extent. The addition of the iron frame greatly enhances the stability of the overall structure, ensuring that the massage chair can remain stable and reliable in a variety of use scenarios, whether it is carrying users of different weights, or experiencing frequent functional adjustment actions, providing solid support for users.
