Imagine the warmest coziest robe or towel you have ever felt, combined with the soothing hug of a loved one. This is the sensation that sensory challenged children receive from the Sensory Sleep Sak. The Sensory University weighted Sensory Sak is professionally manufactured to therapists standards. Our blankets have a weight of 8 lbs and are 45 x 60 inches. This is the maximum weight offered to prevent suffocation hazards. All weight is distributed across the top of the Sak so that the child has a padded comfortable surface to sleep on. Unlike less expensive blankets, our blankets are double insulated to prevent the sound of beads moving as this is a huge distraction to children with sensory disorders. This Sak can be used as a bed blanket, a wrap around, a sleeping bag, or it can even be doubled to use as a large weighted pad or shoulder weight. We offer the Saks in two color combinations. Double blue for complete calming, or blue / red which can be used as a calming agent on one side, and a great source of visual stimulation on the other. Many children with sensory issues are extremely attracted to the color red, while the color blue seems to create an instant calming sensation. The blue / red combo give you the best of both worlds, and has the same soft texture on both sides. We offer the double blue color for children who just can't handle vibrant colors. Washable Not for use with small children who are prone to suffocation. Use should be supervised at all times. Never place in crib with an infant.
