Maternity Pillow?

💋👶🏽J-Me👶🏽🚒
I keep seeing all these great pics of ladies with their Maternity Pillows. Or seeing conversations about how great their pillow is. Does anyone have any recommendation on what pillow is the best? 
A girlfriend of mine got one off eBay, and it's way to small and has gone flat. So I thought it would be great to get some first hand experience before putting out $100 on a pillow. 
Thank you in advance 😊
