Pillows for side/stomach sleeping?
So let me preface this by explaining that I'm male, and that I am here using the word "pillow" in the literal sense, and not making a tasteless joke everyone has heard before.
My wife is at least a 38DD, which is probably not huge by the standards of this subreddit, but she is an otherwise petite 5' tall. So proportionally... Anyway, she wants to lie on her stomach to sleep sometimes (especially lately, owing to an unrelated surgery) but when she tries this her shoulders end up in an awkward, unsupported position--which aggravates her spinal stenosis. The pillows we have on hand don't help. They're either too little or end up holding her neck oddly.
I've searched the subreddit, but there aren't any current results, and so my question for you is: what kinds/brands of pillows do you use, for those of you with similar sleeping preferences? She won't spend money on herself so my plan is to acquire a few options and return what doesn't work. I'd appreciate suggestions.
