I have looked at a Posture Pleaser, but don't want to put money in another adaptive device that doesn't work, so when I had to FMQ last night, I put two 1 pound weights in a child's packpack I purchased for $1 at a garage sale yesterday. It seemed to help a lot. I also have a pads that angles my seat forward and a lumbar support on some chairs that need them.
Now how do you get rid of the leg spasms in the night after a stint of sewing?
