Osaki OP-4D: The First Massage Chair That Actually Gets Your Shoulders

The Osaki OP-4D Master redefines what a massage chair can do with a first-of-its-kind over-the-shoulder massage system. Ten precision airbags work in synchronized motion — rotating and compressing in patterns that closely mimic the feel of real hands — delivering a soothing, wrap-around shoulder experience unlike anything else on the market.

The intelligent body scan technology automatically maps your unique shoulder height and width, precisely positioning the massage rollers for a customized, full-contact massage tailored to your body.

Dual massage nodes on each shoulder pad mimic the feel of human hands, delivering a realistic, hands-on massage experience right where you need it most.
