When you purchase an Osaki OS-4000LS Massage Chair, you choose a model that provides one of the best massages on the market. Osaki’s L-Track massage will deliver therapeutic massage from your neck to the back of your thighs and back again. There are Foot Rollers, too, along with an adjustable ottoman. 24 airbags supply compression massage to large muscle groups. And, that is just the beginning!
Standard Features of the Osaki OS-4000LS
Air Compression Massage
You will enjoy restorative compression massage from the 24 airbags located throughout the Osaki OS-4000LS. These airbags are placed on either side of the shoulders, waist, legs, and feet. There are also airbags in the small of your back or lumbar area, waist, arms, and hands.
Automated Programs
There are 6 automated programs in the Osaki OS-4000LS. You can select the one you want from:
Relax: a gentle use of airbags only to help you relax
Manual Air: select which airbags are used and which muscle group to massage
Deep Tissue: the massage rollers press deeply into your muscle groups
Full Air Compression: uses airbags only to compress all of the major muscle groups
Energy Stretch: promotes ligament and joint flexibility
Dual Action: a full body therapeutic massage in which the chair also rocks
Adjustable Ottoman
If you are a taller person, you may have encountered the frustration of fixed-style ottomans. The Osaki OS-4000LS has a spring-loaded ottoman that easily adjusts to your height with a simple push of your foot. Automated programs that change the chair position work easily with this feature.
Shoulder Massage
Most massage chairs neglect a crucial area of your body that carries a lot of stress – your shoulders. The Osaki OS-4000LS has customizable shoulder massage, making this one of the best massage chairs for people with broad shoulders.
Heat Therapy
The lumbar area of the Osaki OS-4000LS has built-in heating pads. This helps to relax the large muscle groups in that part of your body, which makes your massage more successful.
Space Saver
The Osaki OS-4000LS needs only 4 inches in which to go into a full recline mode. This makes it a top choice for small areas with limited space.
Body Scanning
As soon as you sit in the Osaki OS-4000LS and activate it, it will conduct a body scan. This sends the rollers down your back to determine your width and height so that your massage experience will be customized.
Vibration
You can turn on the vibration option of the Osaki OS-4000LS. This gently vibrates, helping your muscles relax.
Manual Mode
There are 4 manual modes to choose from:
Shiatsu
Tapping
Rolling
Kneading
Special Features of the Osaki OS-4000LS
L-Track Technology
The Osaki OS-4000LS uses advanced L-Track technology to provide you with a professional massage that goes from the back of your neck, down the spine, and beneath your seat and thighs. This technology massages 50% more of your body than chairs that just travel up and down your back.
Zero Gravity Technology
NASA created the first zero gravity seats for the space program, and that technology has been transferred to your Osaki OS-4000LS. With a press of the button, the chair will recline to the Zero Gravity point in which the chair back completely supports your weight. Your feet will be above your heart, aiding circulation.
Foot Rolling
Your feet will feel brand-new after their therapeutic massage in the Osaki OS-4000LS footrest. Rollers in the bottom of the ottoman press acupressure points all along the bottoms of your feet for a sense of rejuvenation.
