> I always end up with a bad backache after sitting here at the computer > for hours on end. Barb, I also spend probably more time than is good for me at the computer. when at a computer show about four years ago, I was pretty tired from all the walking around, trying to avoid people who wouldn't avoid me, etc. and my lower back was giving me *hell*. I came across a booth selling a product called "NADA-CHAIR" (hey, I just had a thought - does that mean "no chair"? Boy, ya can't say *I'm* slow!). One of the sales people invited me to sit down (didn't need much urging - :-) ) and to try the device on. I did, and within minutes was in such bliss, that they jokingly offered me a job just sitting there with a silly look on my face, because several people looked at me, and asked to try the device! :-) It is a little weird, but really works. It is made of heavy rip-stop fabric. The main section is a padded half-belt about 9 inches that sits across the small of the back, with the top roughly level with the top of the pelvis. (There is a thin front belt with velcro closure to keep it in place until you take the next step.) On each side, there is a loop of webbing about 1 1/2 inches wide, (similar to seat-belt material) with adjustable buckles, and sponge-rubber knee pads. With the wearer in a sitting position on a stool, bench, or backless or wide-seated chair, the webbing loops are placed around the front of the knees, with the rubber pads sitting on the know of bone just below the kneecap. Two clips on the insides of the loops are brought together, to lock the knees into one unit. The user now leans as far forward as they can, and shortens the adjustable web straps as much as possible. The user then leans back as far as possible, arching the back and straightening the shoulders. The effect is immediate and terrific. All strain disappears from the back muscles and spine. After about 5 minutes, the user will find that they can lean forward even more, re-tighten the straps, and then lean back again. I find that I can continue to get aid and comfort from the device for about one to two hours, but then the device itself starts to become an irritation. I just take it off, and my back seem to be quite normal. It comes with a booklet of instructions and exercises, and extra straps to perform leg-stretching exercises. For travelling, the whole thing disappears into itself with zippered pockets. It is made in the US. The address Is NADACHAIR, 783 NE Harding St. Minneapolis, MN, 55413 USA (I think. Becoming a little faded. And the label is, too - :-) ) Phone is 1-800-722-2587. Nope, I don't get paid for sayin' this. Just the satisfaction of knowing someone else might get the relief I have had.
