Are knitted (chunky) weighted blankets better than glass-bead blankets?

They serve different use cases. Specialist-subreddit consensus is that open-knit chunky blankets like Bearaby-style designs breathe far better and look nicer as decor pieces, while glass-bead quilted blankets distribute weight more uniformly and tend to cost less per pound. Knitted blankets are usually preferred for couch/lounge use; bead blankets dominate for in-bed sleeping.
