About this item Cotton [Bonus] A matching color duvet cover included. [Innovative Design] The 7-layer system design adapts to the curve of your body for optimal comfort and the 4.7x4.7-inch smaller sections allow for more equitable weight distribution. It includes more glass beads and less fiberfill for enhanced temperature regulation. In addition, a three-dimensional lock bead stitching method prevents leaking of beads. It has the finest stitching (0.25mm per stitch) to avoid movement of weight between compartments. All of these attributes make it a superb blanket. [Unique Sleeping Experience] YnM provides a natural means of calming the body for a good night's sleep. It is a wonderful sensory blanket for adults and children to help them relax and feel at ease. Great gifts for your loved ones. [Sizing Guide] Please select a weighted blanket measuring 80x87 inches or 88x104 inches for sharing. Refer to the lighter person’s body weight to choose the couple’s blanket weight. (see the Size Chart) [Loops] It has 16 sturdy loops for securing the duvet cover (available separately) to prevent slippage. [Easy Care] Machine washable in a gentle setting. Tumble dry on a low setting or line dry. Use a mild detergent and avoid bleach. If you use YnM weighted blanket with a duvet cover, then you can just wash the light weight duvet cover instead of washing the heavy inner weighted blanket. [Reminder] Weighted blankets are not meant to hang off the edge of your bed. This concentrates weight into the areas where it is needed most. On you! So a weighted blanket is much smaller than an ordinary blanket.
