This review is a couple days in the making. When you receive the package, it comes compressed so you have to let it decompress. The directions says to shake it for up to 5 minutes, this helps with making sure everything fluffs up evenly. I gave it 24 hours before I used it (per recommendations). IT’S SO COMFY! My bed had been aching my back before but not anymore. It’s soft but it doesn’t have you sinking in it. I definitely recommend this for people who feel tired when they wake up after a restless night of tossing and turning!
