What Is All33?
Lucy’s original All33 code graphic — kept for reference. The store link currently errors out; see below.
All33 was the company that made the Backstrong C1, a chair built around a “rocking” saddle seat that moves with your pelvis instead of holding you rigid — the pitch was better circulation and less strain than a standard office chair, with folding arms so you could tuck it into tight spaces. It picked up attention a few years back partly through celebrity backing, and it sold directly through its own site rather than big retail chains.
We checked two independent things and both point the same direction:

- all33.com’s security certificate has been expired since November 2025 — over eight months as of this check — and the site returns a bare “403 Forbidden” rather than a working storefront. A certificate that’s been left to lapse for that long isn’t a blip; it’s a site nobody’s maintaining.
- The alternate Backstrong-branded domain (backstrongchair.com) is now a parked domain — it redirects to a generic domain-for-sale landing page with no chair content at all, not an active store.
We haven’t found an official shutdown announcement from All33 — no press release, no “we’re closing” note — so we can’t say with certainty the company itself is gone. But between the expired storefront and the parked backup domain, the buying-a-chair-from-All33 part of this story appears to be over as of July 2026. We’re treating the offer as discontinued rather than leaving up a “click here for $50 off” button that may not go anywhere.
Looking for an Alternative?
Unfortunately, we don’t currently have a verified-working discount code for another ergonomic office chair brand on this site — we checked our own gaming-chair affiliate link and found it’s also broken (the retailer’s storefront is gone), so we’re not going to send you there either. Our honest advice: search for “Backstrong C1 alternative” or “saddle seat office chair” directly, and check reviews before buying from any single-brand DTC site that isn’t also sold through a marketplace with return protection.

Frequently Asked Questions
Does the All33 coupon code HAPPY100 still work?
We can’t confirm it as of July 2026. All33’s own site is returning errors (expired security certificate, 403 responses), so there’s no working checkout to test the code against.
Is All33 the same company as Backstrong?
Yes — All33 is the company, and the Backstrong C1 is its flagship chair. Both names point to the same product.
Has All33 officially announced it’s closing?
Not that we found. We’re going on technical signals — an expired site certificate and a dead alternate domain — rather than an official shutdown statement, so treat “appears inactive” as the accurate read rather than “confirmed closed.”
When was this checked?
July 2026. If All33 comes back online with a working store, we’ll update this page and re-test the code.
