Backstrong Review
What Happened to All33? (2026)
The Backstrong C1 is the only chair in the world that allows natural movement of the pelvis and back stimulating circulation, improving flexibility, and encouraging an increase of oxygenation and respiration.
All33A Kickstarter Chair Built Around Movement
The Backstrong chair started life as a Kickstarter campaign before landing on the All33 website, and its whole design revolved around one idea: a static seat isn't good for your back.
Its Sit In Motion technology let the saddle react like a rocking chair, cradling the lower back to relieve pressure points and support posture, while the C1 was built to allow natural pelvic movement the brand said helped circulation and flexibility. The design also included fold-up armrests and construction using recyclable materials.
We're being upfront here: All33/Backstrong is confirmed out of business, with company assets sold at auction (per multiple 2023-2024 reports). We have no way to verify current pricing, the $50-off code, or whether any current owner of the brand's assets is still selling this chair.
Because of that, we've removed the purchase link and the discount code. The design details above describe the chair as it existed while the company was operating, not a current, purchasable product.
Why We Love It
- Sit In Motion saddle was designed to cradle the lower back and support posture
- Allowed natural pelvic movement said to aid circulation and flexibility
- Fold-up armrests for closer desk seating
- Built with recyclable materials
Considerations
- All33/Backstrong is confirmed out of business -- we could not verify current pricing, availability, or the $50-off code
- Only two style choices existed: Fabric or Vegan Leather
A Closer Look
How the Backstrong Chair Is Built
The chair's design centers on a handful of purpose-built elements rather than a simple upholstered seat.
Sit In Motion Saddle
A bottom seating section that moves like a rocking chair, cradling the lower back to relieve pressure points and improve posture.
C1 Pelvic Movement System
Allows natural movement of the pelvis and back, said to stimulate circulation and improve flexibility.
Fold-Up Armrests
Armrests fold up to let you scoot closer to the desk or push the chair fully in when done.
Proceed With Caution -- This Company Has Shut Down
All33/Backstrong is confirmed out of business, with assets sold at auction -- we've pulled the purchase link and discount code rather than point you to a dead end.
