To the person who suggests making a weighted blanket yourself:
It can be done, and has many upsides! There are good patterns available online, and you can pick comfy fabrics. BUT if using the pvc pellets as filling, be very careful and thorough about reinforcing the seams. You will probably do best with access to a sewing machine, and should go over the seams more than once. The beads are heavy enough to put a lot of stress on the stitches. They come out easily, and in addition to making a mess, they can get in ears/noses while sleeping. It is *not* fun to have those removed if they get stuck.
