Most are made from polyester—many listings specify 100% polyester—using woven or plush fabrics; several descriptions also note a polyester shell.
They’re described for use at daycare, preschool, sleepovers, and for travel/on-the-go.
Many include built-in handles or a carrying strap plus a Velcro closure so the mat can roll up for easy transport and storage.
Some nap mats have an attached pillowcase that fits a standard pillow (pillow not included), while others include an attached pillow and a cozy blanket all in one.
Some nap mats include a "This Belongs to" name label where you can write the child’s name.
