FAQS

The ALL33 moves all 33 vertebrae in your back to assist you with proper posture and give you a sense of relief. Unfortunately spending much of your day in a seated position can leave your spine sore, stiff, and in pain because you are putting stress on the muscles and discs of your back and neck. This position results in tightness of your hip flexors such as the iliopsoas muscle and ischemia (restricted blood flow) of your buttock muscles—the gluteus maximus, which is important because it supports the spine. Our chair works to resolve these issues and make it easier for you to sit!

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. 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! ALL33 Chair Reviews

The human spinal column is made up of 33 vertebrae (bones) - 7 vertebrae in the cervical region, 12 in the thoracic region, 5 in the lumbar region, 5 in the sacral region and 4 in the coccygeal region.

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. Testing by (BIFMA) shows that our chair supports up to 275 pounds.

This is normal! When we get comfortable in our bad posture, our bodies need a period of readjustment. During the first few days, or even weeks, you may find that your body is engaging muscles that have not been used in a long time (or ever!). These muscles are supposed to be used when sitting to hold your body and back erect. Since they have likely not been used (or exercised) in this way, it is much like the experience one would have when going to the gym and lifting weights for the first time in awhile. Your muscles may feel sore when being triggered and used for a bit.

***If your soreness or discomfort continues for a longer period, we urge you to stop using the ALL33 Chair and consult a medical professional to diagnose your specific condition and situation.

There is no set limit to the sitting time but we encourage everyone to get up and move around at least 1 time per hour to help increase blood flow and stimulate your muscles

We have made the chair as green as possible. The plastic used in the chair is recyclable, but most significant is the fact that the upholstery pieces are replaceable. We are sick of seeing chairs discarded in back alleys. With the ALL33 chair you can replace the upholstered components for a refreshed Chair!

We are considering this feature for the future, but this chair is designed to be effective and comfortable without one! Picture your vertebrae as links in a chain, with each spinal region made of multiple “links”. When one link moves, it affects the others. In biomechanical terms, this is referred to as a kinetic chain. The base of our spinal kinetic chain is the pelvis. If the base is well supported, then the rest of the “links in the chain” have the foundation to be supported as well. This is why it is important to sit back in your seat- to allow the pelvis to be supported in your chair, and provide the foundation for lumbar, thoracic and cervical support. This effectively eliminates the need for a head rest. ALL33 instantly reacts to give you a neutral spine posture and thus eliminates the benefits of a head rest.

The arms on this model are designed to flip up out of the way. We have positioned our arms in the most optimal location to fit a broad percentile of users, also considering the arm location in regards to the desk. We want users to be comfortable moving close to the desk and not having interference with the arms. If this interference is a problem based on the desk or the Chair height we have made the arms fold completely out of the way giving full access to the work area.

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 59.6 inches (or 4.96 ft) or over 73.4 inches = 6.1 ft.

Standing all day means your joints are bearing weight, which leads to compression and degeneration. Your circulation is static, and standing increases the load on your heart to return blood up (against gravity) to your lungs. The answer is to keep yourself moving, sitting and standing, but if you have to sit, sit in a chair that lets you move!

Vegan leather (or Ultraleather) is synthetic leather that’s soft and animal-friendly. Today's synthetic leathers feel great, are more durable than animal leather, and are easy to clean. The material also breathes well, making your chair cool to the touch. We use vegan leather because of all these benefits, plus it still looks great while being eco-conscious!

Our knit polyester fabric has 3-way stretch that conforms to the cushions and gives when you sit. It is stain and water resistant to ensure your chair stays clean, and passed a “color fastness” test showing resistance to abrasions, UV light, and wet/dry crocking.
