Osaki 4000T Massage Chair

The Osaki 4000T massage chair is one of our best selling chairs and for good reason. This chair is packed with features and at a price point that makes it even more desirable among massage chair enthusiasts. Let the feature-rich Osaki 4000T relax you in the comfort of your home.

Computer Body Scanning Technology
Computer Body Scanning is included which helps the rollers precisely map your back. This is important because everyone's back is shaped differently and body scanning will allow this chair to do its job properly.

Computer Body Scanning

Massage Rollers
The massage rollers start at the back of your neck and go all the way down to your lower back area.


Osaki 4000T Back Rollers

You can adjust the intensity and speed of the massage rollers as well. You'll want to do this to get the massage that feels best to you.

Heated Lower Back
Conveniently situated in the lower back area are 2 heating pads. Heated massage can be great for loosening stiff muscles and helps create a more relaxing state.

2 Zero Gravity Positions
The zero gravity position is widely recognized as the ideal position to enjoy a massage. Originally discovered by NASA, sitting in the zero gravity position allows you to almost feel weightless. The near-weightless feeling is achieved by taking the pressure off of certain parts of your body.

Zero Gravity

While in the 2nd zero gravity position, the weight of your back will be resting against the backrest which will make the massage rollers feel more powerful.

2 Stage Zero Gravity

Airbag Massage
Osaki has done a great job placing the 46 airbags throughout the chair for your maximum enjoyment. These airbags are programmed to massage you in the right place, at the right time.

You can also adjust the intensity of the airbags for a more custom massage.

Arm Airbag Massage
With this chair, your arms are well taken care of due to the arm airbags that inflate to apply a compression massage.

Arm Air Massage

Shoulder, Lumbar & Hip Squeeze
In the upper to mid part of the chair, airbags inflate and deflate at various times which will allow your body to twist. This creates a relaxing stretch that is performed on your shoulders, lower back, hips, and thighs.

Seat Vibration Massage
Placed in the base of the seat is a vibration plate that when activated gives a soothing vibration massage to the back of your thighs.

Foot Massage
Do you enjoy a good foot massage? If so, the 4000T doesn't disappoint in that area.

On the bottoms of your feet, you'll feel 2 rows of foot rollers as well as airbags on the sides of your feet. The airbags help to hold your feet into place and the foot rollers perform a deep kneading style massage.

Foot Rollers

The foot rollers also make use of reflexology which helps stimulate acupuncture points and makes for an overall healthier state of being.

Calf Massage
Your calves won't be forgotten due to the multiple airbags on the sides and the back of your legs and feet. The airbags will perform a compression massage which feels nice and also helps to increase blood flow.

Automatic Leg Scan
Will people with different leg lengths be using this chair? That's no problem at all.

At the beginning of your massage, the chair will extend out fully and then retract.

Leg Extension

Once the foot portion of the chair has reached your desired length simply press your toes down firmly to tell the chair where to stop. Doing this will ensure you get a proper foot and calf massage.

Full-Size Controller
You'll appreciate the robust, full-size controller that's both easy to see and use.

You can access the manual functions of the chair by flipping down the cover on the front. While in manual mode you can choose from kneading, tapping, shiatsu, rolling, combination, and Swedish massage styles.

Remote Control

The controller lets you choose the massage type, intensity, speed, and location.

    Wireless Remote Control
    Want a smaller controller that's both wireless and compact? No problem.

    The Osaki 4000T comes with a wireless remote that's on the top right of the main controller. This smaller remote will let you toggle between the main features of the chair. This comes in handy when you're in the reclined position and don't want to reach up for the main remote.
