I used to be irritated by the way seatbelts chafed my neck, but eventually I grew enough that they no longer cut so high and rested across my chest like they were meant to. With regard to weighted blankets, you can make one for about half the price of buying one if you're any good at sewing; my mother made me an eight pound one for my birthday last year and the fabric and the beads together cost around $70. Weighted lap pads are also a good starting place because they're a lot cheaper than the blankets are.
