Upon launching, the Gravity Blanket weighted filling featured a High Density Plastic Poly Pellet. However, to ensure we're providing the highest quality product – and one that is environmentally friendly – we are in the process of switching to biodegradable micro glass beads. As of Feb 2019, our Space Grey Original Blanket and Galaxy Blue Original Blankets are filled with glass beads. We are in the process of switching our Cooling Gravity Blankets to the new glass bead material and expect this process to be complete by Summer 2019.
In terms of the outer cover, the Original Gravity Blanket features a duvet that is made of velboa plush (100% polyester) and our Cooling Gravity Blanket and Faux Fur duvet is made of 87% polyester and 13% spandex.
