Massage chairs have come a long way since the very first one was created in Japan in the late 1950s.

I’ve talked about the origins of the massage chair before, but the story is fascinating.

The first massage chair was created by a man who sold sewing machine parts. His daughter suffered from severe headaches, and he was looking for a way to help her when nothing else seemed to provide relief.

Using parts from sewing machines, he created a simple roller mechanism and attached it to the back of a chair. His daughter could sit in the chair and press the back of her head against the rollers, which helped relieve her headaches.

That was essentially the birth of the massage chair.

Eventually, manufacturers developed a cavity down the center of the chair that allowed the rollers to travel up and down the back, rather than focusing only on the neck. The earliest designs used two rollers, and they remained that way for many years. The tracks were also completely straight.

Then came the S-track. This curved track was designed to follow the natural contours of the spine, allowing the rollers to provide a more comprehensive back massage.

Manufacturers eventually added two more rollers, bringing the total to four rollers.

Then the L-track was introduced. The rollers could follow the S-shaped curve of the spine and then continue underneath the buttocks, creating the L-shaped track that we commonly see in massage chairs today. This is also referred to as an SL-track or L-track.

Next came split-track chairs. These chairs divide the roller track into two sections—roughly the upper two-thirds and lower one-third—with a hinge between them. The hinge can be made from metal or durable plastic and allows the L-track to flatten as the chair reclines.

That design is particularly useful for stretching, because it allows the chair to create a different angle and movement than a traditional fixed L-track.

Eventually, manufacturers developed chairs with two separate roller mechanisms. The hybrid chair we discussed earlier was one of the first of its kind, featuring two rollers in the upper mechanism and four rollers in the lower mechanism.

It’s amazing to see how much massage chair technology has evolved from those original two-roller designs.
