Osaki OS-4000CS Zero Gravity Massage Chair

The Osaki OS-4000 CS is part of the bestselling OS-4000 Series, offering an array of innovative features like  space saving technology, L-Track Massage, Adjustable Shoulders and Zero Gravity. Each chair in the OS-4000 series has something unique to offer.

Computer Body Scan

Equipped with the latest technology, the massage rollers map out the back’s curvature with great accuracy, translating into a more effective massage and hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized.

Space Saving Recline Technology

Typical massage chairs consume a more space due to the chair being in a reclined position. Massage chairs require up to 3 feet behind the backrest for the chair to fully recline. Titan’s innovative design team has engineered a space saving technology that slides the chair forward as the chair reclines. Fully reclined this chair can be positioned within 6 inches of a wall for maximum space saving.

L-Track Massage

L-Track system massages from the neck, past the glutes, and down to the back portion of the thighs. The track in which the massage heads move are curved to contour the back and glutes area.

Zero Gravity

Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This feature improves spinal decompression and decreases muscle tension of the spine. There are 2 stages of zero gravity, the 2nd being more reclined. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.

Lumbar Heating Pad

On each side of the lower lumbar area there are individual heating pads. The heat therapy is a great compliment to the roller and airbag massage. Heating the body’s temperature is known to increase blood circulation and loosen tense muscles. The heating pad is not intended to exceed more than 30 minutes of usage a day.

24 Airbag

Osaki strives to make its chairs efficient and extremely reliable. Other brands will market their chairs to have 70+ airbags for a full body massage. The engineers believe with more airbags and more valves, the more strain the air pump endures. With more moving parts there’s a greater chance of something failing. Osaki has been engineering its chairs to reduce the airbag count and at the same time increasing the surface area by using more pliable and durable material which have received great feedback. All 24 airbags are strategically placed to optimize the squeezing effect of the shoulders, arms, hands, hips, calves and feet.

Adjustable Outer Shoulder Massage

Osaki has taken custom fitting to a whole new level by adding adjustable outer shoulders. The outer massage airbags are typically stationary and depending on the height and width of the user, the shoulder massagers can be ineffective because of positioning. With the ability to adjust to 3 different widths, the user can improve the strength and fitting of the outer shoulder massage.

Value and quality for the price

The massage chair was delivered within 36 hours of the order being placed. The delivery service placed the box in my enclosed patio without incident. Unboxing was simple. The chair came completely assembled and needed only to be plugged in. The build quality is excellent. The variety of included programs will easily allow for a multitude of focused therapies. I would recommend this chair to others and would definitely purchase it again.

Really Comfortable Massage Chair

Having used this chair for two weeks, I could only say it is the best decision I had made.
I really love the massage in my lower back and my hip.
It relieves my tired body after my daily work. I use it every day before I go to sleep.
I had considered different brands and prices and I finally purchased this one because the style looks luxurious.
It is fully matched with my home and carpet.
The material is high quality and comfortable while I am sitting on it.

Jose C.
