Bearaby's Cotton Napper is a knitted weighted blanket to help you fall asleep faster and feel calmer, naturally. Made of 100% cotton, this breathable weighted blanket is pre-washed for buttery softness— just like your favorite T-shirt—and ideal for all seasons. The weight on your body helps stimulate the production of serotonin (the happy hormone), reduces cortisol (the stress hormone), and increases melatonin, which helps you fall (and stay) asleep. **Content + Care** \- 100% Cotton \- Machine wash cold \- Imported **Size + Fit** \- S: 10 lbs - 40" x 64" \- M: 15 lbs - 40" x 42" \- L: 20 lbs - 45" x 72" \- XL: 25 lbs - 48" x 72"
