Back Width Adjustment & Massage Range (GT700)

	The S shaped rail curve is based on a combination of human ergonomics and back massage principles providing excellent support to the body. The S rail guarantees that the back is accurately positioned for a proper back massage. The width can be adjusted from 6 to 21cm, with three levels.
	Intelligent mechanical hands can move up and down on the neck, shoulder, back and waist. They can automatically determine the back curvature and extend as wide as 21cms. Vertically the mechanical hands travel 135cms, providing full back coverage.
