I can only tell you how it fits me. I'm 5'2 and overweight. It worked fine for me but would be more comfortable on a thinner person. The thinner you are, the more room it gives the baby. The heavier you are, makes it tighter for the baby. My baby is 12lbs now and she fits fine still, but only in the sitting position.
i am 5'1, not really big, but pregnant, the problem was I am a G Cup, so would this be the correct size?i already put a bid in, i have been looking for one of these for a while
