4 Massage Functions

•    Rolling: the motion of the rollers mimic human touch massage or hands pressing and sliding up and down the spine. This technique is used at the beginning of a massage to warm the muscles and increase blood flow to the muscles.

•    Clapping: Professional masseuses use this technique by patting the muscles of the back with the palms of their hands. This helps to reduce muscular pain.

•    Kneading: the rollers make circular motions which help to reduce tension in muscles and reduce knots.

•    Tapping: this technique mimics fingers tapping along your spine which has been shown to reduce headaches and tension.

Body Scan

Many users of this chair have said that one of their favorite features is the body scan. The sensors in the chair scan your whole body as you sit in it and adjust the chair automatically to personalize the massage for each person who sits in it.

This technology means the rollers can change to match your body shape and can also change the height and width to accommodate most body shapes. This means the rollers don’t miss out any areas of your body, thus giving you a massage unlike many chairs in the same class.

Massage Styles and Pre-sets

The Osaki has 5 different massage styles including, Vibration and airbag massage, Swedish, pulse mode and Shiatsu.

There are 3 different massage groups:

1.    Neck and shoulders
2.    Back and lumbar region
3.    Lower body massage

There are also 5 different types of massage you may choose.

1.    Therapy
2.    Circulation
3.    Relaxation
4.    Healthcare
5.    Smart mode

Advantages for you to have a massage chair in your home are obvious. You may suffer from a bad back or take part in lots of sporting activities. Due to the versatility of this chair, you can choose a different type of massage depending on your needs. Or if you just want to relax after a hard day at work you can do that too.

Air Bags

The 4000 model has 48 airbags that cushion the whole body which emulates a full body massage by a qualified masseuse. The positioning of the airbags means they are able to work on pressure points, which enhances the massage experience.

The airbags are the secret.

They give you that human touch to your massage as they envelop the body, hugging it for the greatest effect.

•    There are 10 airbags on the chair just for your feet.
•    10 more which work on your calves,
•    3 bags cushion the seat,
•    2 cushion your back,
•    2 for your shoulders,
•    3 around your neck area and
•    3 more which hug your hips.

The combination of all the airbags gives you the feeling of a full body human touch massage in your own home. There are so many airbags they hug your body at every important point.

There are also 5 pressure settings to help you create a personal experience. And you can intensify the effects of the massage to suit your own preference.

Advanced Rollers

The advanced roller mechanism on the Osaki mimics the human touch of a professional masseuse. They knead and grasp but can also focus on specific problem areas of your body. This means you can target areas of your body that need more attention.

If you have back problems, the 30-inch roller covers the entire length of the back, from the base of your neck all the way down to the lumbar area.

The rollers are made of soft material and feel like the feel of human thumbs. The Osaki has two modes to choose from, medium and narrow. This means you can adjust the rollers for the best massage for you.

Ergonomic S-Track

One major factor to consider when you are thinking of buying a massage chair is how well it works with the shape of the spine.

The Osaki os-4000 has an ergonomic design that has been developed to follow the natural S-curve of the spine. This feature also works with the body scan feature. Thus giving a specifically targeted massage to common problem areas such as the lumbar region, the neck and shoulders.

Heat Therapy

This feature is a major advantage if you suffer from lower back pain. Heat in the lumbar region of the chair can ease tension and reduce inflammation. The combination of the massaging action of the airbags and rollers with heat will encourage blood flow to the painful affected back muscles. The heat can also enhance your feeling of well-being and relaxation.

Seat Vibration

The Osaki os-4000 has a special vibration massage plate located on the back part of the upper legs. This is very relaxing and soothing.

Zero Gravity

NASA developed zero gravity technology, and it has been utilised to good effect in this massage chair. This technology has also been adopted by many domestic and commercial products over the years. It allows the chair to recline to a degree where your heart is in line with your feet giving a feeling of zero gravity.

osaki os 4000 chair

This feeling of weightlessness has been researched to be the best posture for the greatest effects of a massage chair. Because of the position of the body during the massage in the chair, the pressure is displaced throughout the body.

This benefits the whole body because it increases circulation and reduces strain on the spine. This obviously reduces back pain and relieves pressure and strain on the heart. This is believed to be the best position to induce relaxation and enable you to enjoy the benefits of the massage.

The Osaki 0s-4000 has 2 zero gravity settings and you can find the best position to recline for your needs.

Leg Extension with Feet and Calves Massage

The Osaki 0s-4000 also has a leg rest. This has an inbuilt sensor that scans your legs and provides the most comfortable fit. If you are a tall person the leg area of the chair can extend to accommodate your personal dimensions.

When you choose the foot and calves massage the sensor can target the acupressure points on the soles of your feet. This can help with many different health conditions.

If you suffer from pain in your calves and feet the kneading action of the rollers can increase circulation and help reduce pain. The airbags enhance this process and give a more effective massage.

When you sit in the chair the leg areas will extend then retract. Once it has retracted to the desired point you press your toes down firmly which tells the chair to stop.

Full-Size Easy-to-Use Remote

The viewing screen on this chair is one of the largest of any of this class of chair.

This makes it easy to see what functions to choose and activate. The flip down cover gives access to the manual functions. You can tailor the functions for your own specific needs and select or isolate certain areas and types of massage.

Wireless Remote

The control panel is easy to use but you also have a small wireless remote. This enables you to control the chair and massage controls whilst in the reclined position.
