Osaki OS 3700 Massage Chair Review 2024

The Osaki OS 3700 massage chair is one of the few massage chairs priced under $3,000 to offer arm massage, shoulder massage, and foot roller massage. In most cases, manufacturers of massage chairs in this price range exclude these premium features to keep the price down. But somehow, Osaki managed to sneak these high-end — and very therapeutic — features into the OS 3700.

Too good to be true?

In this article, we’re going to walk you through every feature, detail, and function of the Osaki OS 3700 to help you decide if this massage chair is worthy of your dollars, or if it really is too good to be true.

Features of the Osaki OS 3700 Zero Gravity Massage Chair

Air Massage Technology

Osaki’s signature airbag massage technology makes up the core of the OS 3700 massage chair. 36 airbags throughout the chair provide therapeutic air compression massage to nearly every part of the body.

The airbags in the OS 3700 are Osaki’s new and improved “Next Generation” airbags that have been redesigned and engineered to offer more performance with fewer total bags in the chair. With fewer airbags in the chair, fewer valves and pumps are needed, resulting in lower energy draw and quieter operation.

Shoulder Air Massage

As mentioned above, shoulder massagers are generally reserved for chairs in higher pricing brackets. While the shoulder massagers on the OS 3700 aren’t as robust or adjustable as those found on Osaki’s higher-end models, they use the same Next Generation airbags found throughout the rest of the chair and deliver a very effective air compression massage to the shoulders.

When activated, either as part of an automatic massage program or operated individually in manual mode, the shoulder massagers inflate and deflate, pressing the shoulders back into the chair. This action gently massages and stretches the muscles in the shoulders and upper arms, relieving tension that often accumulates in these areas.

Arm Air Massage with New Armrest Design

The fact that the OS 3700 massage chair comes equipped with arm massagers makes this chair hard to ignore, especially for the price.

The arm massager uses Osaki’s Next Generation massage airbags to deliver compression massage to the forearms, wrists, and hands. The armrest on the OS 3700 has been completely redesigned and is something you won’t find on any other Osaki massage chair model.

A unique aspect of the new armrest design is that instead of staying fixed in place, the armrest can move forward and back up to four inches. This movement of the armrest accommodates the movement of the chair when reclining, allowing the arms to remain in the perfect position in the armrest whether the chair is upright or reclined.

Buttocks Massage

Along both sides of the hips, there are sets of airbags that massage the hips and buttocks area. In addition to providing direct compression massage to these areas, the hip and buttocks airbags help keep the user in place while other massage actions are performed.

During certain preset automatic massage programs, the buttocks and hip airbag massagers inflate, squeezing and holding your hips in place. Then, as you recline, the squeezing action of the hip and buttocks airbags keep your body in place while your upper body is massaged. This keeps you from slipping around in the chair and makes the upper body massage actions more effective.

Foot and Calf Massage

Airbag massagers inside the leg ottoman administer air compression to the calves, ankles, and feet. The compression and squeezing action of the airbags loosens up the muscles of the legs, relieves tension, and can aid in reducing swelling.

Foot Massage Rollers

Another premium feature, the OS 3700 has single-row reflexology massage rollers located under the feet. These rollers massage acupressure points on the soles of the feet. The foot and calf airbag massagers help press the feet down onto the foot rollers for an even more invigorating massage.

30-Inch Massage Roller S-Track

In addition to the full body air massage throughout the chair, the OS 3700 features a 30-inch massage roller track in the backrest. The massage roller track features Osaki’s S-Track design that gives the track a complementary “S” shape that closely matches the curves of the human spine.

The main benefit of the S-Track is that it keeps the massage roller heads in close contact with the body throughout the entire massage range.

Massage chairs that don’t have an S-Track often have “linear” tracks that are notorious for applying too much pressure in the upper back and not enough pressure in the lower back. Thankfully, Osaki outfitted the OS 3700 with a full S-Track system to deliver the most effective roller massage possible.

Full Powered Recline

While the OS 3700 doesn’t have Zero Gravity recline like many other Osaki massage chairs, it does feature full-powered recline. Using the remote, you can recline the chair all the way back until your back is parallel with the floor.

Heat Therapy

Located in the lower portion of the backrest on the OS 3700 there are two heating pads. When activated, the heating pads warm up the lower back area, helping the muscles to relax for a more therapeutic massage experience.

The heating pads can be used on their own or in conjunction with any of the preset massage programs.

Vibration Massage

Osaki added a high-frequency vibration plate beneath the seat of the OS 3700. When used, the vibration plate administers a pleasant vibration massage to the buttocks and hamstrings on the back of the legs.

Like heat therapy, vibration massage can be activated on its own or in conjunction with the preset massage programs of the Osaki OS 3700.

Intuitive Handheld LCD Remote

The remote of the Osaki OS 3700 massage chair is very easy to use and gives you full control over every function of the chair. The bright LCD screen shows you every setting and function that is currently active on the chair.​

Massage Techniques and Preset Massage Programs of the Osaki OS 3700

5 Therapeutic Massage Techniques

The massage rollers in the backrest of the chair produce five distinct massage techniques. You can enjoy these massage techniques individually with the chair in manual mode or as part of the preset massage programs. They are:

6 Preset Massage Programs

Each of the six preset automatic massage programs is made up of a combination of the roller massage techniques mentioned above plus full body air massage and foot roller massage. Each program offers a different massage experience and therapeutic benefit, giving you plenty of options to choose from depending on what you want your massage to be that day.

Massage Intensity Control and Customization of the OS 3700

Massage customization is an important factor to consider when choosing a massage chair. You don’t want to end up with a massage chair that is way too intense, or worse, one that doesn’t provide enough massage pressure.

Thankfully, the Osaki OS 3700 has three features that allow you to adjust the intensity of the airbag massagers as well as the speed and width of the massage rollers.
