Product Highlights

The Osaki's OS-4000LS is a fantastic addition to the 4000 series line-up-for just a little bit more money, you get the added benefit of a more efficient next-generation airbag technology, foot rollers and a spring-loaded extendable ottoman. The 4000LS features a 42" L-Track design which allows the rollers to follow the natural curvature of your spine and then curve around your glutes in order to massage your glutes and hamstrings. The rollers begin massaging at your neck extending all the way down your spine until wrapping beneath your glutes and then to the bottom of your thighs. The Osaki OS-4000LS is able to accommodate people from 5'2" to 6' tall.

L-Track Technology

The Osaki OS-4000LS Massage Chair features a 42" L-Track roller which allows maximum massage and roller coverage to the body. The rollers begin to massage at your neck, follow the natural curvature of the spine until wrapping beneath the glutes in an L-shape to finish at your hamstrings.

Foot Rollers

Located along the bottom of the foot rest are rollers that target the acupoints along the bottom of your feet. This is a therapeutic feature that will help rejuvenate sore and tired feed and leave you feeling refresh.

Zero Gravity Position

Inspired by NASA, scientists in an effort to reduce spinal compression to astronauts during rocket launch into orbit, the 4000LS offers a zero-gravity position for your massage. Physicians believe that this is the "healthiest way to sit" and clearly the best way to receive the most out of your massage.

Airbag Air Compression

Osaki has really improved their airbag technology by reducing the number of airbags while increasing their overall coverage and improving the materials used. You will find that this chair runs quieter due to less valves and compressors firing. Enjoy gentle (or higher intensity squeezing) to: shoulders, lumbar, waist, arms, hands, legs and feet. Airbags work well in conjunction with the massage rollers in order to promote blood flow and accelerate healing.

Space Saving Technology

In the past, massage chairs required several feet of clearance from the wall in order to fully recline and enjoy all of the options. Now, with the Osaki OS-4000LS Massage Chair you can set your chair within 4" of the wall making this chair a favorite among those people who don't have a lot of space. The chair slides forward as it reclines eliminating the massive spacial requirement. This is a great option for smaller rooms.

Body Scan

Right when you sit down to begin your massage, the Osaki OS-4000LS scans and maps out your body to adjust the chair to the perfect height and width settings in order to ensure that all the acupressure points along your back are covered. A good body scan really creates a custom massage tailored specifically for you.

Lumbar Heat Therapy

The Osaki 4000LS allows you to enjoy gentle heat to the lumbar area of your back. Heat has been proven to help loosen and relax the muscles in order to prepare for a more therapeutic and healing massage. Heat also helps to improve blood flow and circulation enhancing the overall experience.
