i got mine from babies galore and its the long noodle kind.. i have the top up near my head then it goes under my belly and between my knees... its also great for back support behind me or for propping one side of my body up when i need to lay on my back but am not allowed so its like almost laying on my back haha...
think its called a bed buddy or something was only around $40 i think too i would deffinately recomend it!!
