This buttery, soft and breathable, organic cotton 15 lb weighted blanket is ideal for all seasons. Weighted blankets have been medically proven to aid naturally deeper sleep cycles. The weight on your bodies stimulates the production of serotonin.(the happy hormone), reduces cortisol (the stress hormone), and increases melatonin, which helps you fall and stay asleep. I purchased one for myself otherwise I would keep it. Purchased as a gift, never been used, in original canvas bag.
