Hi, I’m Dr. Alan Weidner from Massage Chair Relief, and today we’re going to talk about the roller mechanism of the new Japanese-made D.Core 2 massage chair.
At first glance, the roller mechanism might look like any other. But there are a couple of very interesting and important—and somewhat subtle—differences.
Most massage chairs use what’s called a quad roller system, meaning they have four rollers: two at the top and two at the bottom. But this chair is different. It has two rollers at the top, plus a middle set of arms, each with one roller on either side, and a bottom set of arms, also with one roller on each side. That’s 10 rollers total—I’ve never seen a roller mechanism with that many!
It’s fascinating—and the massage it gives is comprehensive. You feel it in your neck, shoulders, and especially your lower back. And I’ll tell you, it really digs into the low back, which is rare.
I’ve got a bit of an excessive lumbar curve, so I personally appreciate how this chair really targets that area. Most chairs don’t have a strong enough forward motion in the rollers to reach that deep—but this one does.
Now, another thing that stands out about this mechanism is the texture of the top rollers. They’re not smooth like most roller balls. Instead, they’re made of a grippy rubber material with a corrugated texture—not sticky, but definitely more tactile.
You might see a close-up of them now on your screen. They actually remind me of those little decorative pumpkins you see around Thanksgiving—ribbed and rounded. That grip allows the rollers to grab the muscles more as they rotate over your back, which creates a very strong, effective massage.
We really like this chair.
And it’s incredibly quiet. I had it running earlier, and you could barely hear it. That’s rare. Most massage chairs make at least some noise. Of course, technology has improved dramatically over the past 10 years, and many modern chairs are quieter. We recently did a video on the DualMax split track, and that chair was quiet too—but this one is almost silent. It’s quite remarkable.
This is a Japanese-made massage chair, so you know the engineering, testing, and build quality are second to none.
One last point: the D.Core 2 massage chair uses an L-track, meaning the rollers travel from the neck down the back, underneath the seat, and then back up again—all 10 rollers working simultaneously along your spine. It’s a full, continuous massage.
Anyway, I hope you found this video helpful. If you did, please give it a thumbs up, subscribe to our YouTube channel, and help us spread the word about massage chairs by sharing this video—or any of our videos—with your friends and family on social media.
