Weighted Blankets

Weight works through even distribution, not total mass. Glass beads are the reason: they are dense enough to add pressure without bulk and small enough to sit in stitched pockets that stop them drifting into one corner overnight, which is the failure mode of cheaper poly pellet fills.

The usual complaint about weighted blankets is heat, because the layers that hold the beads also hold warmth. The cooling build addresses that with a breathable shell; the heated one goes the other way and adds a powered element for cold rooms.

If weight is not what you are after, blankets and throws covers fleece, sherpa and faux fur, and comforters and duvets covers full bed layers.
