Weighted blankets

Hello all,

My 13 year old daughter with ASD has major difficulties sleeping. She has sensory processing issues and I have been recommended to use a weighted blanket, which she wants to try. However having looked at a few suppliers they seem to be hugely expensive, and I'm worried about spending so much money when she could easily decide she doesn't like it.

She has also said she is worried about it being noisy.

Can anyone recommend a supplier who doesn't charge the earth, and can anyone who uses one advise if they make a noise? We are looking at ones with plastic pellets.

Thanks very much
