The Osaki OS-4000LS 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.

• Intelligent Body Scanning: 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 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 Reclining: 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 Heat Therapy: 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 Air Cell Full Body Compression: 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 Shoulder Width: 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.
