100% Breathable Natural Cotton.RECOMMENDED WEIGHT/SIZE – The weight of the blanket you order should be 7%-13% of your weight, which would help you sleep better and faster. Choosing the suitable weight would make the most of the blanket. Due to its weight, it’s not necessary to choose oversized blanket. PREMIUM MATERIAL – The weighted blanket is made of 100% breathable natural cotton, which would make it cooler and more durable than normal blanket. The filling is environmental non-glue polyester padding and Hypo-allergenic,non-toxic,odorless Glass Beads. NEW PROCESS – We improved our technology step by step. The new process can make the square much smaller, which would make weight distributed evenly inside the blanket. The updated process would fix the problem that the glass beads move massive around inside the blanket. To prevent the glass beads leakage, we add two layer microfiber inside, which is also breathable and would not make it hot. QUALITY GUARANTEE – There are internal quality checking for each process. We have professional QC team. The QC team would check the blanket from step to step during the manufacturing. After packing before shipping, we would also select several blankets and recheck the quality. If there is any defect, we would fix the problem or pick it out. We aim to provide our customers the best goods with best serve. WARNING – Some people are not recommended to use the weighted blanket. Please do not use it for children under 5 years old.
