I got one from Walmart very very comfortable
I have the BB and had the same problem until I adjusted the toggles and spread out the lining so it is flatter. Worked a dream!
I got a BB hug me from FB marketplace as they're a bit pricey and it's still an adjustment but definitely helps being able to change the firmness so it's just getting used to what's comfortable for you, I use mine mostly for sofa naps and it's amazing 😂
I got this one from Amazon and I love it! https://amzn.eu/d/2l1vNH4
Following because I am also looking for one… I had one from Amazon for my first pregnancy and I absolutely hated it, it was too big and to form was unable to sleep with it at all…
