Product Description

Memorial Day Sale Osaki OS-4000LS Massage Chair

Quick Product Features:

  • 42″ L-Track Roller System: The OS-4000LS Massage Chair is designed with the increasingly popular extended roller system, or L-track. With the OS-4000LS, the massage roller track will not only massage the neck and entire back like every other chair does, but also swings into the seat itself to provide a deep massage along the gluteal muscles. The chair’s powerful 42 inch roller system massages from the neck to the buttocks
  • 24 Airbags: The rest of the body not covered by the 42″ roller stroke — including the shoulders, arms, hands, lower back, calves and feet — are massaged using the chair’s 24 air compression bag system. The airbags in the chair have been redesigned such that there are fewer of them in the chair overall but cover more surface area, thus reducing the strain on the chair itself. The airbag massagers not only cover hard-to-reach areas, but they work together with the roller system to stretch the body
  • New! Foot Rollers: Dual reflexology foot rollers located on the bottoms of the footrest will apply a kneading style massage to the soles of your feet that target the acupuncture points. In addition, airbags will compress and decompress along the sides of your feet to push your feet deeper into the rollers in order to enhance your massage. Foot rollers are including in the OS-4000LS to revive tired and sore feet
  • Zero Gravity “Weightless” Recline: The popular massage chair recline position perfected by NASA will place your feet 30 degrees above your heart and evenly distributes your weight across the chair. This recline position relieves compression along the spine, relaxes the neck and back, increases circulation and blood oxygen levels, expands lung capacity, and reduces tension throughout your entire body
  • Shoulder Width Adjustment: The OS-4000LS includes an innovative shoulder adjustment found in just a few chairs. Almost all massage chairs have a stationary shoulder airbag system that cannot be altered, which restricts users with broader and narrower shoulders from getting the maximum benefit out of their massage session. However, with the OS-4000LS’s shoulder adjustment, you can modify the chair’s shoulder width up to three settings to find a fitting that suits your body best
  • Lumbar Heating: The OS-4000LS includes heating elements along the lower back area to warm up your tense back muscles, which allows the rollers to work your back more effectively
  • Space Saving Recline: The design of the OS-4000LS permits you to place the chair within 4 inches of the nearest wall, minimizing the amount of floor space required in the room you plan to place the chair in. Compare this to other non L-track chairs that require anywhere from 1-2 foot of clearance in front of the wall
  • 6 Auto Programs: Simply tap a program on the remote control and the automated program will start within seconds. Choose from Deep Tissue, Stretch, Energy, Relax, Full Air, and Manual Air
  • 4 Manual Massage Techniques: When you use the chair’s manual settings, you can pinpoint any trouble areas you want the chair to focus on. For example, if you’d like the chair to focus on the neck, you can target that area of the body and have the rollers work on that region of the body until you’re satisfied. Manual massage techniques include Kneading, Tapping, Shiatsu, and Rolling
  • Body Scanning Technology: When you sit in the chair and it’s being powered up, the OS-4000LS automatically detects your body frame and locates the spine and makes micro adjustments as needed to give you a customized massage specifically for your body frame
  • USB Charging Station: You can use the USB port located next to the remote control holder to charge up your cell phone, MP3 player or other devices while you enjoy your therapeutic massage
  • Easy to Assemble: The chair comes in two boxes: the main body of the chair and the foot rest. The entire chair is already pre-assembled with the exception of the foot rest. You will simply need to connect the foot rest to the main body of the chair and it’s fully assembled. It will take approximately 20 minutes at most to fully assemble

42″ Extended Roller System (L-Track)

The Osaki OS-4000LS Massage Chair comes with a 42″ roller track and is designed with both an S-Track and L-Track scheme. In layman’s terms, the “S-Track” follows the natural “S-shaped” curvature of the spine.

In all S-Track chairs, the roller massage cuts off at the tailbone area; but with the OS-4000LS, the quad rollers veer into the seat of the chair to massage the gluteal muscles, including the piriformis and sacroiliac muscles. It’s called an “L-Track” because in combination with the “S-track,” the massage stroke makes a rough “L” shape.

With the OS-4000LS, you get the best of both worlds. The L-Track roller system massages from the neck, down your entire back, and finally reaches your buttocks and thighs.

New! Foot Rollers

Dual mechanical rollers are located underneath the soles of each feet that provide deep tissue, therapeutic kneading to the bottoms of the feet. While this is occurring, airbags will inflate and deflate on the sides of the feet to create a squeezing-like action. The intensity of the airbag pressure can be controlled from the remote control.

Airbags also inflate and deflate in the calves region, providing a rejuvenating calf massage.

Zero Gravity Recline

The innovative and increasingly popular Zero Gravity positioning is a NASA inspired design. When the Zero Gravity button is chosen on the remote control, the legs are placed at heart level. This “weightless” position promotes better circulation, reduces the vertical pressure on the back, and promotes spinal decompression. This is a must-have feature in all massage chairs.

24 Air Compression Massage Pieces

Because the OS-4000LS has an extended roller system that covers a larger swath of the body, fewer airbags are needed overall to massage the critical areas of the anatomy not covered by the 42″ massage stroke. The airbags massage the shoulders, arms, hands, lower back, calves and feet. The air intensity can be adjusted by pressing the “Intensity” button. There are three airbag intensity options — from from mild to strong.

Adjustable Shoulder Width

The OS-4000LS is one of the few massage chairs that has a shoulder width adjustment to accommodate users of various heights and builds. Most chairs typically have shoulder massagers that stationary and can not be adjusted. This can often neglect not only taller and shorter users, but people who have broader and narrower shoulders. With this chair, this feature takes care of that for you. There are three levels of adjustments available, from the maximum of 9.85 inches to the minimum of 7.09 inches.

Space Saving Recline

As is the case for most L-track massage chairs, the chair will slide slightly forward during your massage session. Thus, the design of the chair allows you to place the OS-4000LS within 4 inches of the wall even during the chair’s maximum recline. Non L-track chairs will require up to 2 feet of clearance in front of the wall. This makes a perfect feature for people who have limited space to work with or want the chair that doesn’t take up a lot of floor space.

6 Automatic Programs

The OS-4000LS comes with six touch-and-go automated modes that target the entire body. The auto modes featured on the OS-4000LS include Deep Tissue, Stretch, Energy, Relax, Full Air, and Manual Air.

Auto program descriptions:

  • Deep Tissue: This auto program engages the full body in a deep tissue massage. This program focuses on the neck, shoulders, waist and hips.
  • Stretch: This auto program consists of a full body stretching auto program, including the back muscles, hands, hamstrings and the rest of the body.
  • Energy: The perfect auto program to choose when starting your day. This mode will deliver a light, stimulating tapping massage throughout the whole body.
  • Relax: This auto program will start with a slow kneading and heavy tapping massage, which progresses into an in-depth massage that targets the neck and lower back.
  • Full Air: This auto program takes advantage of the chair’s airbag technology. It will apply a full body air pressure massage to the shoulders, arms, palms, lower back, buttocks, thighs, calves and feet. The intensity of the air massage can be adjusted by pressing the “Intensity” button.
  • Manual Air: This auto program will activate the airbag massagers to massage the areas of the body you want to target, including the shoulders, arms, palms, lower back, buttocks, thighs, calves and feet. As is the case in the Full Air mode, you can also adjust the intensity of the air massagers by pressing the “Intensity” button.

Customized Manual Mode

With the OS-4000LS, you can dive into the remote control’s manual mode to pinpoint specific areas of the body you want the rollers and airbags to target. For example, if you have a sore neck, you can localize the massage in that particular area and only that area. You can also set the width of the rollers (from wide to narrow), the position of the rollers and more. The manual mode massage techniques include Kneading, Tapping, Shiatsu, and Rolling.

Vibration Massage

The OS-4000LS has two plates in the seat of the chair that can be turned on in order to enjoy a soothing vibration massage. This feature can be activated by pressing the “Vibration” button on the remote.

Lumbar Heat Therapy

The OS-4000LS has two heating modules in the lower back region of the chair that helps soothe away muscle tension. Heat therapy not only loosens up the lower back muscle fibers, but will allow the rollers to provide a deeper massage across the lower back and lumbar region.

Spring Loaded Extendable Ottoman

This chair will allow users of virtually all heights and builds to use the chair. Because of that, the OS-4000LS is designed with a spring loaded feature in the foot ottoman that can accommodate users who are up to 6’4 in height. When you sit in the chair, if you want to extend the foot ottoman, simply push with your legs to extend it out. You can also manually adjust the legrest via the remote control.

Body Scanning Technology

The OS-4000LS comes with the latest in body scanning technology. The chair will map your body frame when it’s starting up and customize the massage rollers for your body build. Whether you’re 5’1 or 6’3, the chair’s body scanning feature makes it a versatile chair for the entire family.

USB Charging Station

Charge your mobile phone or MP3 player via the USB charging port while you enjoy your massage session.

    This is a great chair. It is sleek, slim and doesn’t take up too much room because it is space saving.

    The ways to adjust strength are great with 5 different levels. I like the relaxing massage auto function on the chair and the foot rollers are just on point. I would recommend this chair to many people. It is a great chair and affordable!
