The Gravity Blanket is made up of a supersoft microfibre outer duvet and an inner layer of micro beads. The gridded stitching ensures that the beads are evenly distributed and don't do that weird "shifting" thing that down pillows can do. The duvet zips open, and both parts of the blanket are machine washable. As someone whose home is mostly decorated in neutral shades, I really love the versatile grey colour.
