It is shaped like that - I think the brand is Leachco Back and Belly and I bought it from Toys R Us. It isn't cheap, but soooooo worth it! You can use it later on as a nursing pillow and is great for propping yourself up in bed. It is just fantastic not having to rearrange pillows when rolling over and because it is on both sides of you it can't hit the deck!

Downside (or not! ) is that it does provide a bit of a barricade between yourself and your partner!!
