100% Cotton REVERSIBLE MINKY/BAMBOO COVER INCLUDED: The cool bamboo side is perfect for warmer nights, while the ultra-plush minky side is so cozy you’ll never want to get out of bed! All of our fabrics are superior to other blankets. The bamboo is 300TC Lyocell (organic) vs. Viscose which uses harsh chemicals. Our minky is 195 GSM, much more soft & velvety compared to cheaper minky blankets. HIGHEST QUALITY INNER BLANKET: The inner weighted blanket is 100% percale cotton (233TC) vs. most other blankets that use polyester or the cheapest cotton. Using fewer, higher-quality layers makes it breathable, durable, machine washable, and comfortable to use even without the cover. NO WEIGHT BUNCHING: This is the #1 complaint from our customers who bought a cheap weighted blanket before trying ours. We spent a lot of time designing a blanket that prevents the beads from bunching within the pockets and the blanket from bunching within the cover. PERFECT WEIGHT: All of our blankets are optimized to an ideal weight per square foot based on user testing, not based on the inaccurate percent of body weight model. Just select a size and you can rest assured it??s the perfect weight. USA COMPANY & SATISFACTION GUARANTEE: We are a midwestern company that LOVES our customers and pride ourselves on values, quality, and service. Try our blankets for up to 30 days and if you aren’t satisfied for any reason we’ll provide fast, friendly service and a full refund.
