Osaki OS-4000LS Features

Osaki OS-4000LS Massage Chair L-Track

42" L-Track Massage

The Osaki OS-4000LS massage chair is equipped with a 42″ L-Track design. The quad roller system massages your neck, entire back, and trails underneath the seat to reach your buttocks.
Osaki OS-4000LS Massage Chair Foot Rollers

Foot Rollers & Leg Airbags

Dual mechanical rollers target your feet’s acupoints and therapeutically knead the bottoms of your feet. While this is occurring, airbags inflate against the sides of your feet to create a squeezing-like motion.

Airbags also squeeze your calves, delivering a rejuvenating leg massage.

Osaki OS-4000LS Massage Chair Lower Back Heat

Lumbar Heat

Two heating modules are located in the lumbar region to help soothe away muscle tension. Heat therapy loosens up your back’s muscle fibers and allows the rollers to penetrate deeper into your spine.
Osaki OS-4000LS Massage Chair Adjustable Shoulders

Adjustable Shoulder Width

The Osaki OS-4000LS is one of the few massage chairs featuring an outer shoulder adjustment to accommodate users of various builds.
