In order to get the benefits your BackStrong C1 was designed to provide, you must use it correctly. First off, that means that you have to sit back in your chair, so that your butt is all the way to the back. This allows the chair to guide your spine into proper alignment and stack your vertebrae, relieving your back from the weight of your head. 

There is no set limit to how long you should spend sitting in your BackStrong C1,  but we encourage everyone to get up and move around at least once per hour to help increase blood flow and stimulate your muscles. Providing yourself with short bursts of exercise or gentle stretching will not only help invigorate you physically, but will also help with focus.


Adjusting Your BackStrong C1 Chair 

Your BackStrong C1 was designed to be adjustable to most people’s needs. You can adjust the seat height, the tilt and tension, and you can also flip the arms all the way up and out of the way in order to scoot close to your desk.

Getting Used To Your BackStrong C1 

The BackStrong C1 has an adjustment period; it’s perfectly normal for your back or another part of your body to feel sore when you first start using it. 

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.

***If your soreness or discomfort continues for a longer period, we urge you to stop using the BackStrong C1 and consult a medical professional to diagnose your specific condition and situation.

Upholstery Care

The BackStrong C1 is exceedingly durable, but proper care is still crucial. In order to ensure it remains in good condition, you must take care to clean it regularly and keep liquids (including sweat) away from your chair.

ALL33 Vegan Leather

To clean your BackStrong C1’s vegan leather, use a slightly-dampened microfiber cloth. Simple sprinkle the cloth with a little water, with the leather clean from dirt and light stains, and leave the chair to air dry. 

Leather cleaning products work well on our vegan leather. Make sure to spot test the product on a small area before cleaning your chair completely. Spray a small amount onto a clean microfiber cloth and gently wipe clean.


ALL33 Fabric

Over time, it’s natural for fabric to trap loose particles and dirt. These can be easily removed with a vacuum. Clean any spills as soon as possible by blotting with a dry cloth or paper towel, taking care not to rub the stain into the fabric.

Stubborn spots may require the use of a fabric cleaner or stain remover. Spray a small amount onto a clean microfiber cloth, and clean according to the cleaner’s instructions.
