WHY ALL33
You see, most chairs’ seats are bolted to their base. This allows for no dynamic movement in the hips and pelvis. As a result, your body doesn’t get the range of motion it needs, and you can develop pain throughout the body, poor circulation, compromised posture and low energy levels
ALL33’s BackStrong C1 is different. We threw out the playbook and designed a one-of-a-kind seat. Actually, it’s more like a saddle. It’s not bolted to the base, either; it swings from the arms of the chair to allow for full range of motion in the hips and pelvis. It also frees your lower back to move independently, so whether you lean forward or backward, the seat will move with you.
No more slouching, hunching or leaning to one side.
How are we able to do this? Through our SIM Technology (SIMTEC).
What’s so special about SIMTEC?
As a matter of fact… What is SIMTEC?
SIMTEC is short for Sit-In-Motion Technology, and it’s what is so unique about the BackStrong C1 chair.
The result? You activate your core without even realizing it. The whole time you’re sitting in a BackStrong C1, SIMTEC keeps your body in a naturally athletic, comfortable position.
And you won’t find this technology on any other chair. We’ve patented it, so if you want full range-of-motion and noticeably less pain when you sit, the BackStrong is the only place you’ll find it.

Competitors have tried to imitate us -- you can find contoured saddle seats, minimalist back support, and other knock-off features on many other “high-end” models, but at the end of the day, they just can’t match BackStrong C1. That may be because unlike other chairs, the BackStrong C1 was designed by a world-renowned chiropractor with A-list clients like Shaquille O’Neal, Justin Bieber and Paula Abdul. He used his 20+ years of medical practice and partnered with one of the world’s foremost chair designers to create the world’s most comfortable, ergonomic office chair.
Only the BackStrong C1, with its Sit-In-Motion Technology, can...

- Relieve back pain
- Activate the core to align the spine and prevent slouching
- Stimulate circulation
- Allow for natural movement of the hips, pelvis and back
- Improve flexibility
- Boost energy
- Encourage the increase of oxygenation and respiration
- FIX THE WAY YOU SIT
All of this means a life with less nagging, chronic pain, and we could all use more of that. Back pain is debilitating. It takes all the fun out of life, and robs you of precious moments with loved ones. Back pain is almost always a symptom of some dysfunction in the body that gradually gets worse over time. BackStrong C1 allows you to live pain-free… with no limits.
And with BackStrong C1, the benefits aren’t just physical
You can be proud of how and where you sit as you build your career and life for yourself and your loved ones. BackStrong C1 improves posture which naturally boosts confidence. It’s true -- studies have shown that when you are sitting upright with correct posture while performing a task, you tend to have more confidence in your abilities.
This means not only will your body be more geared toward success… your mind will as well.

And at the end of the day, you get out of your BackStrong C1 with more energy -- not less, as with other chairs -- and know you’ve become a stronger, more capable individual, every single day.
