When it comes to making the choice on what filling you would like to provide the weighted aspect to your weighted blanket, there is an array of options to choose from. In this blog, we’ll compare two of the most popular choices in the weighted blanket world, micro glass beads and plastic pellets, so that you will be able to make a more informed decision when purchasing a weighted blanket. 


If you’ve already started your weighted blanket browsing journey, you’ve most likely seen the first option we’ll discuss today, micro glass beads. Although micro glass bead filling can be perceived as being a quieter option over plastic pellets because of the size difference, micro glass bead filling will not be as long-lasting. Unlike the plastic pellets, the already small micro glass beads will, over time, rub against each other, eventually turning into sand. This will not only make your weighted blanket harder to wash and take longer to dry properly, as sand tends to clump up when in contact with moisture, but will widen the possibility of filling getting out through small holes in your blanket, leading to a mess as well as an ineffective weighted blanket. In addition, there have been reports of lead and arsenic found in micro glass bead filling. This is a major hazard that could lead to health problems.


As an alternative, plastic pellet filling, which is used in Mosaic Weighted Blankets, has a longer life-span, as well as significantly decreased possibility for the pellets to rub together leading to a finer substance, like sand. This means that, with a weighted blanket filled with plastic pellets, you won’t have to worry about filling falling out as much as you would if your weighted blanket were filled with glass beads. Also, plastic pellets are hypoallergenic and non-toxic, so you won’t have to worry about the health threat of lead in the filling as you may with glass bead filling.
