Most of these massage chairs are power assisted. They can also be reclined, with the leg and back areas both at the same time. Some brands can be controlled wirelessly, while some have separate electrical controls for foot and back rest. Most of these massage chairs too are between 20 to 22 inches in width, while at least 17 inches in depth. This helps the user determine if he can fit in the seats. The depth of the chair alters the leg length, thus people who have short legs can only us the leg rest function when they are upright especially if the chair is too deep for them.
