Osaki OS-4000LS Features
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.
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.
Zero Gravity
The Zero Gravity recline position perfected by NASA places your legs level with your heart and evenly distributes your weight across the chair. This “weightless” recline relaxes your neck and back, increases circulation and blood oxygen levels, expands lung capacity, and reduces tension throughout your entire body.
Shoulder Airbags
Lumbar Airbags
Arm Pocket Airbags
Waist Airbags
Calf Airbags
Foot Airbags
24 Airbags
Due to the extended 42″ roller system massaging a larger area of the body, the Osaki OS-4000LS requires fewer airbags. Its 24 airbag count is plenty and still targets the key regions of your body.
The airbags compress against the shoulders, arms & hands, lower back, waist, calves, and feet. The airbag strength can be adjusted by pressing the “Intensity” button on the remote. The OS-4000LS offers five airbag intensity levels — from mild to strong.
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.
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. Most chairs typically have one stationary position which can often neglect users who have broader or narrower shoulders. To adjust the shoulder position, firmly press the shoulder panel inward or outward up to 3 different widths.
Body Scanning
The Osaki OS-4000LS features the latest in body scanning technology. When powered on, the chair maps your back, detects your body’s acupressure points, and customizes the massage rollers for your unique body shape.
Custom Roller Techniques
With the Osaki OS-4000LS, you can dive into the remote control’s manual mode to pinpoint specific areas of the back you want the rollers to target. For example, if you have an aching neck, you can localize the massage to that particular area and choose from one of four distinctive roller techniques (Kneading, Tapping, Shiatsu, and Rolling).
You can also set the width of the rollers (three levels of adjustment; from wide to narrow) and speed of the rollers (three levels).
Vibration Massage
The Osaki OS-4000LS has two plates embedded inside the seat which can be activated to enjoy a soothing vibration massage.
Space Saving Recline
The Osaki OS-4000LS slides slightly forward as it reclines, allowing the chair to be safely placed within 4 inches of a wall. This is a great feature for those who have limited space and/or want a chair with a smaller footprint.
Extendable Footrest
The spring loaded footrest can accommodate users up to 6’4″ in height. To extend the footrest, simply push outward with your legs.
4000CS vs 4000LS
The OS-4000CS and OS-4000LS are both the same chair with the exception of one important feature: foot rollers. The OS-4000LS includes rejuvenating foot rollers; the OS-4000CS features a less impressive, airbag foot sole squeeze.
Easy Assembly
The OS-4000LS ships in two boxes: the main body and footrest. The chair is already mostly pre-assembled. Simply connect the footrest to the main body of the chair and you’re ready to begin your relaxing massage.
