I bought the snoogle and HATE it. BTW, if anyone wants to buy it, PM me. I have a pink cover for it that can be washed.
The Snoogle makes my back and neck hurt a lot. It has no support for the lower half of your legs. My webster-technique chiro says my knees need to be aligned and my ankles need to also be separated.
So I lay on my left side and use 2 pillows under my neck and 2 body pillows along my front. one of them under my belly, then continuing down. the other one starts over the other one right below my belly, then continues down to my ankles. I put a small pillow under that at the bottom too so my ankles are aligned. I shove a small pillow under my back also.
It looks like a gigantic barricade, but it's so comfortable! Every once inawhile in the night I'll cheat and throw off my covers and lay on my back for a half hour or so with my legs propped up. By the time I wake up cold it's time to turn back onto my side. If I want to lay on my right side, I just shove my top leg over my partner's legs to cuddle him.
