We have a bearaby blanket. It's a little different from most weighted blankets in that it doesn't have a bunch of little beads or whatever sewn into it for weight, its just knitted from a ton of fabric. Because it is knitted it's very breathable which is nice because I'm a pretty hot sleeper.

It's also probably a little more washable than a lot of other blankets because of that, but you may need to make a trip to the Laundromat to use the big washer.

If you're not a fan of the knit, I imagine you could probably stick it in a duvet cover.
