The Osaki OS-4000LS massage chair uses an L-track massage system to provide relief to more of your body. This track style is designed to wrap all the way under your tailbone and reach the upper part of your thighs. This gives you a 30% extension to the total surface area of your back massage. In addition to this back massage upgrade, you also get the benefits of zero gravity, adjustable shoulders, foot massage rollers, and a spring-loaded extendable ottoman for maximum comfort. Read more about the individual features below to see if this is the massage chair for you.
L-Track Massage System
The L-track massage system features an extra long massage track that reaches down below the hips and tailbone area to the upper thigh. This allows the massage chair to provide a massage to your glutes and upper thighs, as well as your entire back. The 42" track easily reaches all the way up to your neck and provides much better ergonomic support for your lumbar and neck areas so you can relax more easily.
Zero Gravity Position
The zero gravity position was originally designed by NASA as a way to reduce stress on the astronaut's body as they were launched into space. It has since been reappropriated into home massage chairs to help deepen full body relaxation so you receive a much deeper benefit from your massage experience. This position reclines you back and raises your legs to the level of your heart so the pressure of gravity is removed from your joints and spine.
Foot Massage Rollers
This is new to the next generation of OS-4000 massage chairs. The footrest now includes reflexology foot massage rollers that apply a kneading style massage to the soles of your feet so you receive a true head to toe massage experience.
Adjustable Shoulder Massagers
One of the most exciting innovations to massage chairs in recent history is the adjustable shoulder massage. This gives you 3 adjustments that allow you to customize the shoulder massage and make it more comfortable for users of differing heights and sizes. This feature is especially noteworthy if you are above 6' in height.
Lumbar Heat Therapy
Heat is an important part of any massage experience. The Osaki OS-4000LS massage chair uses two heating pads in the lumbar section of the backrest to apply a gentle heat therapy to the large muscles groups in your lower back. This heat helps loosen up tension and ensure you receive the maximum benefit of your massage.
Space Saving Technology
Many older massage chairs can require up to 36" behind the chair to fully recline. The Osaki OS-4000LS massage chair is different. With the inclusion of space saving technology, this massage chair only needs about 4" behind the chair to fully recline. This means you can place your massage chair close to the wall in your home and not have to worry about how much space it is going to take up.
Full Body Air Compression Massage
Airbags have been placed throughout the massage chair to provide a compression massage to parts of your body that are out of reach for the massage roller. This includes your arms, shoulders, hips, lumbar, legs and feet. In total, there are 24 airbags that make up this system all of which help to facilitate stretching motions, and to promote circulation throughout your body.
Spring Loaded Ottoman Extension
The ottoman has been outfitted with a spring-loaded mechanism that allows you to quickly and easily extend the footrest to the ideal distance. The spring ensures there is always ample tension to maintain a quality foot massage.
Body Scan Technology
When you first start a massage program the massage rollers glide up your back to create a digital map of your back and height of your shoulders so it can scale the massage routine to your exact size and shape. This ensures that no energy is wasted massaging in areas that don't benefit you.
