The MyFirst Pillow (approximately 1/3 the size of a standard/queen pillow) is designed for children 3 to 8 years old. Perfect for the little ones! MyFirst stays cool (little kids sweat a lot!) and is fully washable and dryable as often as needed. Great for asthma/allergies. For adults, provides pelvic support if placed between the knees while sleeping on your side without all the bulk of a larger pillow. Great for extra support in your office chair or in the car. All MyPillow® Specialty Pillows are filled with our patented medical grade, nonallergenic fill. Fully machine washable and dryable. 60-day Comfort Guarantee and a 10-year Warranty. 12" wide x 18" long with a 1" gusset.
