Small woman wants hybrid durable bed with good edge support and plush feel

Searching for a mattress is so difficult. I like the sinking feel of pillowtops with some support below. I’m only 105 lbs and I find that there needs to be sufficient softness so that my hips can sink or I feel out of alignment. I feel a pillowtop hybrid is my best bet. In testing beds in stores, I like the feel of a Beautyrest Series 3 medium pillowtop but don’t like its thickness nor the reputed poor quality of the mattress for such a high cost. It seems buying a direct to consumer is the way to go but it’s scary to buy a mattress I haven’t tested. Does anyone have suggestions among mattresses such as Bear, Diamond, Heliz, and Leeesa what might work for me? Thanks for any help!!
