OMG!! ITS PERFECT!  Best comfort and sleep in a long time.  Feels so plush and easy to find the best position, regardless of sitting up in bed or on edge of bed, Im a side sleeper and love this contour feel of support.  Definitely worth every penny!  It plumped up within the suggested 24 hrs, but I waited 48 hrs before putting it on my hospital frame.  All my twin sheets  covers fit perfectly, no smell, no crinkly sounds when I moved. Since Im short, I added my own bedside step stool to make it easier to sit in the middle of mattress.  (LOL) Awwwww, ... Just total luxury, I HIGHLY RECOMMEND this 10 mattress.  Thank You Wayfair for such a quality product.
