Osaki 4000T Massage Chair Features
What's the Difference between the Osaki OS-4000 and Osaki OS-4000T?
There are a couple of main differences between the Osaki OS-4000 and OS-4000T. Those are the addition of foot massage rollers and the streamlined airbag system. The new reflexology foot massage rollers replace the nodule plate that applied the acupoint massage to the soles of your feet when the airbags inflated. The airbag system has had its overall number of airbags used reduced while covering the same surface area. With fewer airbags, there are fewer valves, and an overall lower strain on the chair. As a result, you will see improved reliability in this ideal massage chair as a whole.
Foot Massage Rollers
The new reflexology foot massage rollers feature dual mechanical rollers that apply a shiatsu style massage to the soles of your feet that provide reflexology benefits. The massage rollers of this foot massage chair work with the airbags in the leg rest to provide maximum relief to the soles of your feet. If you are among those who do not like foot massages or just don't like the way this foot massage feels, you can easily turn it off with a push of a button.
Zero Gravity Technology
The Osaki OS-4000t massage chair is a zero gravity massage chair that has been outfitted with a two-stage zero gravity system that allows you to customize your recline as well as other parts of your massage. The first stage of zero gravity reclines your back and raises your legs up to be about even with your upper body. This greatly reduces the strain of gravity on your joints and spine which allows them to decompress more easily and (in some users) cause a sense of weightlessness. Zero Gravity was introduced by NASA a couple of decades ago as a way to reduce stress on the body of astronauts as they were being launched into space. When you apply these same principles to a massage chair you have a recipe for deep relaxation and a much more effective massage.
Lower Back Heat Therapy
Heat has always been an important part of any massage experience. The Osaki OS-4000t massage chair includes two large heating pads in the lumbar area of the backrest to apply gentle heat therapy to your lower back in an effort to help loosen up those often tight muscles in the lower back. This heat allows your back massage to be a little more effective and brings you a much more relaxing massage experience.
Quad Style Massage Roller
The Osaki OS-4000t has a quad-style massage roller. This particular roller design can easily mimic the motions and feel of a human hand so your massage experience feels very realistic. Used in conjunction with the 30" S-track, your back massage will reach from your neck all the way down to your lower back with a uniform massage experience that is ideal for users between 5'2" -6'4".
Truly Ergonomic S-Style Massage Track
The S-track design provides a significant improvement over the old straight track massage. Within a straight track, areas where your back curves away from the track receive a lackluster massage. As the S-track is designed to mimic the curvature of the human spine the massage roller stays the same distance from your back no matter if it's massaging your neck or your lower back. This ensures your back massage is more comprehensive and uniform than that of massage chairs that still use a straight track.
Body Scanning Technology
Body scanning technology is an important feature in any modern massage chair that claims to provide a personalized massage experience. When you choose a massage program, the Osaki OS-4000T's massage rollers will slide up your back in an effort to map the exact curvature of your spine and the height of your shoulders. This allows the zero gravity massage chair to scale the massage routine to your specific size, that way the back massage is always massaging where you ARE in the chair, and nowhere you aren't.
Leg Scan & Extension
The leg scan and extension are an additional part of the body scanning technology. When you choose the zero-gravity button, you will recline back into the first stage of zero gravity the leg rest will extend to better accommodate your legs. This is ideal for taller users who can feel scrunched into the seat. After the leg rest extends all the way out, it will retract again. Once it is in a comfortable position for you, press your toes down on the footrest to stop the scan. This ensures your legs are sitting comfortably within the leg rest and the airbags continue to massage the correct areas.
Powerful Vibration Massage
Two vibration plates within the seat of the massage chair provide a relaxing vibration massage that reverberates up your spine from your lower back. This form of massage is particularly effective at soothing lower back pain and loosening tense lower back muscles.
Spot Massage
If you have ever woken up with pain in your neck or back, this mode is for you. When the massage rollers get to the afflicted area, activate the spot massage to cause the massage roller to focus on that spot specifically. This will greatly help in melting away this pain and any excess tension in your muscles in that area.
Large LCD Display Remote
The remote for the Osaki OS-4000T is a large backlit LCD display that allows you full control over your massage experience. Easily choose from the 5 pre-programmed massage routines, make a few adjustments and sit back and relax while you enjoy your personalized massage experience. The display is very large and easy to read so you will know exactly what is going on with your massage experience at any given point, even when looking from the fully reclined position. This remote also comes with a convenient mini-remote that allows you to control the basic functions of the chair so you don't have to strain yourself by reaching for the remote. Flip down the tab at the bottom to access all of the manual adjustments you can make to your massage including speed, intensity, strength, and more.
Wireless Mini-controller
The wireless mini-remote is a convenient way to control the basic functions of the massage chair from the zero gravity position. Just slide it off the stand as you recline and you won't have to worry about reaching the remote to make simple adjustments.
5 Unique Auto Programs
The Osaki OS-4000T massage chair comes with 5 pre-programmed massage routines. Each of these routines provides a different style of massage experience so you have something that is ideal for almost any situation. If you are just getting started, we recommend the demo program so you can quickly see exactly what this ideal massage chair can do for you. The massage programs include Relax, Therapy, Smart, Circulation, Demo.
Manual Massage Options
If you want your massage experience to focus on a specific area of your body on occasion, then the manual massage options are ideal for you. Choose between three settings Full Body, partial and fixed, and customize your massage style, as well as strength, speed, and intensity so you get the perfect massage for you. Massage styles include Rolling, Kneading, Clapping, Shiatsu, Swedish, Tapping. Within the manual modes, you also have access to 5 adjustable levels of speed and intensity with 3 adjustable widths for each massage style.
Full Body Airbag Compression Massage
The airbag massage system of the Osaki OS-4000T has been streamlined in an effort to reduce the overall number of airbags and improved the reliability of the chair. The airbag system still covers the same surface area on your body, but with 38 airbags instead of 48. The airbag compression massage is designed to help stimulate muscles and improve blood circulation which improves your overall sense of relaxation and well-being.
Arm Massage
Airbags in the armrests provide a compression massage to your hands and forearms to help relax muscles throughout your arms and improve blood circulation to your hands.
Calf & Foot Massage
Throughout the leg rest of the Osaki OS-4000T are airbags that inflate to provide a nice squeeze massage to your lower body. These airbags in the footrest are a nice complement to the newly included reflexology foot massage rollers. As these airbags inflate they press your feet down on the foot massage rollers which improves your overall foot massage and allows the massage rollers to help relieve much deeper tissue that they are normally able to reach.
Shoulder, Lumbar & Hip Massage
The Osaki Os-4000t massage chair includes airbags in the shoulders, lumbar and hip areas to help your muscles in these areas to relax. These airbags are also designed to work in tandem with the back massage rollers to provide a much deeper massage throughout different areas of your back. In the shoulder area, the shoulder airbags inflate and press your upper back on the backrest so your back massage is a little deeper in this area. The same process is applied from the hips and lumbar to do the same for your lower back.
Additional Features
Who is the Osaki OS-4000t massage chair for?
The Osaki OS-4000T is a midsized chair designed for almost everyone between 5'2" to 6'4" in height, and with a max recommended user weight of 265 lbs. Anyone looking for a medium to medium/strong massage this would be an ideal massage chair for you, especially for the price. The OS-4000T has earned its place as a best seller due to the fact that it offers several higher-end features and a quality massage for about half the price of many comparable massage chairs, so you really feel the value of your purchase.
Who is the Osaki OS-4000T massage chair NOT for?
While the height range does go up to 6'4", those with broad shoulders are going to feel a little cramped in this massage chair. So if you are 6'0"+ and are worried about whether or not your shoulders will fit comfortably you may want to consider moving up to the OS-7200h, which provides a bigger frame and a little more shoulder room. This foot massage chair is also not recommended for anyone over 265lbs although it CAN accommodate users who way more than that, it does put additional strain on the mechanical parts and leads to reduced reliability.
