Osaki OS 4000 – Zero Gravity

Osaki OS 4000 Zero Gravity Massage ChairInspired by NASA Technology, the zero gravity position on your Osaki Massage Chair is the perfect position to experience your relaxing massage.

Zero gravity aligns your back relative to your thigh at an optimal level of comfort – the complete weight of your back is supported by the backrest, maximizing the intensity of the massage.

There are two levels of zero gravity, the second level being more reclined than the first, for a customized massage. If you want to relieve pressure on your spine, increase blood oxygen levels and expand your lung capacity, zero gravity is the best option.

In fact, when you recline the Osaki OS 4000 fully and your legs are higher than your heart, you receive the full therapeutic effects of zero gravity.

Osaki OS 4000 Massage Chair – Computer Body Scan

Equipped with the latest technology, the Osaki OS-4000 uses a computer body scan for the rollers to map the curvature of your back with precise accuracy, giving you a wonderful massage that hits all of the key areas.

The Osaki Chair is ergonomically designed with the S-Track Movable Intelligent Massage Robot providing support to your neck, back and lumber area, matched exactly to the curvature of your spine. It even uses your weight and height to make micro-adjustments, so that you truly receive a customized experience.

Two months after receiving it, my husband is still using it at least once a day and he is always raving to friends and family that it has tremendously helped reduce muscle inflammation and has even helped improve his sleep pattern.

My husband suggested in investing a massage chair since I was regularly dropping anywhere from $500-700 a month for therapeutic services, knowing that owning a chair in the comfort of my home would pay for itself by the end of the year. And he was right!

I bought this for my bad back it does wonders for my whole body I love this chair it is better than going to the spa.

Received my chair two weeks ago and my husband, children and friends all love it. It massage the neck on down to the legs. Tremendous value. Spectacular!!
