Whether it's useful or not won't be known until it's actually used. I use Marseille massage chair at home. I don't like it except for its simple and generous appearance, but the massage effect is still ok. After all, it's a massage chair, not an artificial one. There are still differences. The whole massage chair still has some functions, which can relieve muscles and promote blood circulation. It feels good to use only the treadmill at home as fitness equipment.
