Loving sleeping on my Polysleep, I had returned a Silk and Snow mattress bc I found it was too hard for me (I am a petite female and prefer a softer mattress for back/ sleeping). One thing I don’t love is that I have had the mattress now for about a month I believe and the bottom two corners still haven’t settled into the frame, they pucker up from how the mattress was rolled up for delivery. Anything I can do to make it settle?
