Welcome to the forums, Kristine! SAA is definitely awesome!
I guess my item would be microbead pillows. Wonderful for resting sore joints on, like wrists and elbows. Just make sure the pillow isn't stuffed too tightly. You want to be able to squish the pillow around so there's no pressure on the joint.
