Is this "arm pillow" for use at a computer station, while watching TV, while in bed, while driving a car or lunar rover, while... ??? Also, being that pillows are completely flexible, why would it take TWO pillows to elevate one arm.
Please update with a little more detail before my arm falls off.
I searched around the house until I found an old couch pillow that kept its shape well enough to hold my arm up while sleeping. I can flip over with it for left of right sleeping. When I am through with it, I lay it on top of the bed for decoration as I have covered it with a coordinating pillow case.
Ther is currently a pillow on the market, if you dont want to make your own, for breastfeeding mothers who commonly have this problem. It's called The Boppy Pillow I'ts not L-shaped but the idea is the same. (it's actually u-shaped) I used one with all of my newborns and it worked very well .
