Knee CirculationWill the Nada-Chair products cut off the circulation to my legs?
No, the circulation for the legs passes behind the knees. The straps are placed on the shinbone and are designed to absorb pressure without cutting off your circulation. However, it is important to remember that the circulation in the legs is greatly enhanced by movement. Because you will be able to sit for much longer periods more comfortably, we recommended that you take sensible breaks to stand, stretch, walk and breathe deeply at least once each hour.

How long is it recommended to wear the Nada-Chair slings?
The slings can be safely worn all day. While most people report immediate and complete relief from the pain of sitting slouched, you can realistically expect the benefits to continue as long as you wear the sling. And when you stand up or walk after using the Nada-Chair, it is not uncommon to feel a "halo effect" of well being and good posture for sometime thereafter. As with any new product, you may need to experiment and make fitting adjustments to optimize the longest, most comfortable sitting period. Because you will be able to sit for much longer periods more comfortably, we recommended that you take sensible breaks to stand, stretch, walk and deeply at least once each hour.

Which one is best for me? Back-up? Slouch!Buster? S'port-Backer? LumbarJack?
Three considerations can help you make a good decision: 1) your body size, 2) the activity you plan and, 3) the need for accessories. The system of support is identical in all the products so the primary difference is the varying extent which pressure is distributed on the back and knees.

Cush-Shins, Stretch StrapsThe Back-up is the choice for those who want all the accessories included and over twice as much cushion on the knee and back, compared to other models. This is recommended for long-term sitting tasks such as computer work and also for anyone with a bigger body builds. The accessory Cush-Shins distribute pressure on the knee and shin over nearly three times the area making it much more comfortable for longer sitting periods. Accessory Stretch Straps engage the feet to allow hamstring stretching or long-sitting on the ground.

The S'port-Backer is the best support solution for those of small or medium body build. It is light and at the same time provides adequate padding for the knees that is upgradeable with the purchase of accessory Cush-Shins and Stretch Straps.

While the Slouch!Buster provides great support, it has no knee cushions - not the best choice for someone who is heavy and will be leaning a larger body mass against the knee. However, for the more occasional user who has a light body frame or a camper who needs the smallest possible size to pack it's a good solution. Along with the Kiddy-Up, this will work for children.

LumbarJack knee detourThe LumbarJack is the only product we recommend using while driving. Elastic straps detour around the knees and engage the feet to allow complete flexibility and mobility of the legs for working the pedals. With accessory straps, the LumbarJack conveniently converts to a comfortable sitting support using only the knees.

How do I know when I have adjusted the sling properly?
Like a good fitting pair of shoes, the Nada-Chair back slings should fit snugly but not too tightly. Much of the adjustment is self-corrective. If you feel uncomfortable over time, simply loosen the straps slightly. The goal is to keep the low back supported just enough to prevent the sagging that leads to back pain. It is recommended to vary the support by alternatively tightening and loosening the straps when you are sitting for longer periods.

How high should the back pad be on my back?
The back pad should span the lumbar spine with the back cushion approximately centered on the belt line. Experiment until you find the most comfortable position for you.

Will the LumbarJack interfere with my legs while driving?
No. A study of users tested in critical movements such as braking and clutching proved that the LumbarJack does not slow the user. Copies of this study are available upon request.

Will use of the Nada-Chair slings weaken my back muscles over time?
Experience shows just the opposite. Doctors internationally are using the back slings to teach their patients to sit straight. Once trained in new habits of good posture, users find it easier to sit properly without the supports. Primarily, the back-sling acts as a guard against slouching and disc damage because it works like an extra muscle to keep the back supported. Unfortunately, the major contributor to back disease and weakness is the common office chair that provides only the illusion of support while causing the user to slouch against the backrest.

Will the Nada-Chair supports improve the health of my back?
Absolutely! By keeping you from slouching, the back slings can actually prevent progressive spinal deformation and disc degeneration. It is critical to the long-term health of your back that the alignment of the vertebrae be maintained with the natural curves in the back.

Can I use the back slings in an airline, soft chair or couch?
Yes, the Nada-Chair slings will effectively improve your posture in any chair. The back-sling provides the additional lumbar support that most seat backs lack. When using the sling to augment an existing back support, it isn't necessary to tighten the straps as much as when you are depending on the sling for full support.

Can I use the Nada-Chair products while wearing a dress?
Simply tuck the dress or skirt down enough to allow the straps to engage the knees.
