Well, it’s been almost a full 72 hours and I would say this topper is about 85 full. I am hopeful a few more hours can take care of it, but I am knocking a star off because I’ve had 1k king sized memory foam mattresses packed in boxes fluff out to full size in less than 12 hours so I’m not sure what’s going on here. Otherwise, it’s very well made with strong sticking and wonderfully thick straps on all sides to keep it in place. It is slightly smaller that the queen sized bed it is currently on, although I believe this is intentional. Is it worth 100 Maybe more like 70, but I’m not sorry I have it.
