Is 20 lbs the right weight for me?

The common guideline is about 10% of your body weight, so 20 lbs suits adults around 150 to 200 lbs. Lighter sleepers and children should pick the 12 to 15 lb range instead.

Will it make me too hot?

The cotton face and cotton backing breathe better than minky or fleece weighted blankets. It is still a 20 lb layer, so hot sleepers may want it only for cooler months.

The fill is polystyrene pellets, which tolerate a cold, gentle machine wash, but the blanket is heavy and bulky when wet. A front-loading machine or a commercial laundromat is the safer route, and air drying is best.

Does it fit a twin bed?

Yes. At 42x72 inches it covers a twin mattress, though weighted blankets are usually sized slightly smaller than the bed so the weight stays on you.

How does it compare with glass-bead blankets?

Glass microbeads in a stitched grid stay put and feel less lumpy. Polystyrene pellets give a softer, more pillowy drape but can shift toward the edges over time.
