Maybe it's the traffic...or my desk chair...or my adorable munchkin. Whatever the cause, my back has been killing me lately! So when a product called BackJoy came my way, I was psyched to try it. It’s super-simple: just a curved piece of foam-covered plastic that you sit on. Supposedly it cradles your sitz bones and takes pressure off your spine. I was pretty skeptical, but it worked for me—I immediately felt less pain in my lower back. If you’ve got a long commute or spend hours at a desk, it might be worth checking out ($40; backjoy.com). While Backjoy can’t fix problems like my mild scoliosis, it’s a simple way to relieve minor back pain.
