Arm Airbags - Depends on the Massage Chair Model
Arm airbags is pretty much a standard feature in most massage chair models nowadays. People have come to expect arm airbags to some degree. As you may or may not know, arm airbags simply inflate and compress on the parts of the arm covered by the airbags. Most chairs will inflate and compress in a wave-like manner to simulate circulation direction from the extremity to the heart.
There are different modes that various massage chairs use to administer the airbag therapy to the arms. For example, the Omega Montage Premier and the Osaki 2000 massage chairs have clamps attached to the arm rests that can be slid from along the arm rests to be positioned at the forearm position or all the way down to the wrist and hand positions. When we used to have the old Inada D-5 Robochair in our showroom, I used to love using this feature on my hands and fingers. It felt wonderful. From years of knuckle popping, my fingers tend to get a little swollen and tight and this type of airbag massage felt great on my fingers.
Another style of arm airbag massage works similarly to the calf massage of the ottoman. An example of that type of arm massage would be the Osaki 6000 or 7000 massage chair. It basically has an arm "slot" wherein the arm is placed and an airbag above the arm and another below the arm squeeze simultaneously, again in a wave-like motion, to compress the arm...most from wrist to forearm. Here is a video demonstrating the use of the arm airbags in the Osaki 6000 massage chair:
Panasonic uses a nifty arm massage feature hidden underneath the arm rests. The top of the arm rest lifts up and the user slides the arms underneath the top of the arm rest. Then, airbags above and below the arm inflate and compress. This type of arm massage works best on the hand and bottom part of the forearm.
The Inada Sogno Dreamwave massage chair is the first chair to have full arm massage. It has airbags that inflate on the hand, wrist, and forearm, but then also has an airbag on the upper arm as well.
Airbag intensity can be adjusted to the comfort of the user. Some folks don't care much for airbags at all, regardless of whether they are on the arms or legs. But, for those that enjoy them and use them they can provide a very soothing massage of the extremities.
