The concept of the all33 BackStrong Chair is All-American. The research, prototyping, and initial manufacturing for it was all done here in the States. Today, some parts are brought from China, but our chairs are packaged and shipped in the USA by our warehouse employees.

The BackStrong chair was designed to fit the 95th percentile of human beings, meaning it conforms to the same height requirements that car seats must follow. Only 5% of the population may be too tall, and 5% may be too small. For specific reference, these standards are not designed to fit individuals under 4′ 11.5″ or over 6′ 1.5″.

In regard to weight, testing by (BIFMA) shows that our chair supports up to 275 pounds. BIFMA (the Business and Institutional Furniture Manufacturers Association) is the not‐for-profit trade association for business and furniture manufacturers. Since 1973, BIFMA has been the voice of the commercial furniture industry and sets the standards for safety and testing.

Every back is unique, and so are the pains that come with it. Our chair has helped a lot of people with a variety of conditions, including hip and back pain, sciatica, and recovery from surgery. Ask your doctor if this chair is right for you and read our reviews to find out more about all the ways the chair is helping others!

We take pride in our products, which is why every purchase made on our website comes with a 60-day Guarantee (unless otherwise noted at the time of purchase).

Due to the unique functionality of our patented Sit in Motion® Technology, we ask that you keep and use your chair for a minimum of 10 days. This will allow your body to properly adjust to your all33 chair. We recommend that you keep the box your chair comes in until you are certain you are happy with it, as we cannot accept returns without the original box or one of appropriate size.

If you are unsure whether you are experiencing all of the benefits that your all33 chair has to offer, you can contact one of our customer care representatives who will walk you through all of the features, benefits, and adjustments in order to ensure that you are experiencing all that your all33 chair has to offer.
