The affordable price and a large number of features that come standard make this massage chair one to keep on your radar. When the OS-4000 was released, most of the massage chairs that were comparable in features sold for over $4,000. The only massage chair that was comparable in price at the time was the popular Osim uAstro massage chair, which was available through Brookstone. These two massage chairs are made in the same factory and the only differences are the overall look of the chair and the remote control. Other than that they are they are same massage chair. This is most likely why these have become two of the best selling massage chairs.
The Osaki OS-4000 massage chair is loaded with all the features that make up a great full body massage chair. It has auto body scan technology, s-track design, quad roller system, 30” roller stroke, two zero gravity positions, 5 levels of strength and intensity, 48 airbags, lower lumbar heat, and a nice selection of auto and manual massage programs. Let’s take a deeper look at these features.
Advanced Body Scan Technology
The Advanced automatic body scan technology uses optical scanners which will roll up and down your spine. This measures the height and weight of your body and tailor the massage areas to match your exact size and shape.
The ergonomically designed S-Track rolling technology provides better support for your neck, back, and lower lumbar area. Instead of having a linear track like many massage chairs in its class, the OS-4000 uses an S-track that allows the rollers to follow the natural s-curve of the human spine.
Quad Roller System
The quad roller system comes equipped with extra soft rollers. The rollers mimic the feel of human thumbs and fingers to enhance the massage experience. The width of the rollers also can be adjusted to suit the individual needs of each user.
30” Roller Stroke
The Roller Stroke one of the most important features to look at in a massage chair. The Osaki OS-4000 has a 30” roller stroke. This is one of the longer roller strokes on the market. So what does this mean? Well, the longer the roller stroke is, the further the rollers can go up your neck and down your back.This massage chair can comfortably massage a user in between the heights of 5’2” to 6’4”.
Zero Gravity Technology
The zero gravity position, which was made popular by NASA, is where your knees are parallel or raised above the heart. This puts you in a state of weightlessness reducing the strain of gravity on your vertebrae. This helps to relieve discomfort in your back. Zero Gravity also improves circulation and reduces your heart rate putting you in a higher state of relaxation. The Osaki OS-4000 has two zero gravity positions and automatically reclines with just a touch of a button.
48 Airbag Massage Systems
The 48 airbag massage system gently squeeze your arms, legs, feet, and hips while applying rhythmic compressions which will increase blood circulation in your body. This has become a very popular feature on massage chairs over the past few years, and the OS-4000 has one of the most robust air massage systems on the market.
Auto & Manual Massage Modes
The Osaki OS-4000 has a large selection of both automatic and manual programs. It utilizes four massage types: Kneading, Rolling, Tapping, and Clapping. It also has some additional massage styles: Shiatsu, Swedish, Vibration, Pulse, and Air Massage.
