I don't have one but I do like the weight of a nice comforter when going to sleep. I also like having a blanket or pillow on my lap. One, the weight just feels right. Two, we have cats who are lap cats & it prevents them from scratching my legs up lol
Weighted blankets are beneficial for all creatures, of all ages.
I have a quilt that is made out of denim. It feels a lot like a weighted blanket. Except this was made by my maternal grandmother & mom so it's made with a lot of love.
