Tencel Fabric: Tencel is a brand name for lyocell, a fiber made from sustainably sourced wood pulp, typically from eucalyptus, beech, or spruce trees. The fabric is known for its silky smooth texture, breathability, and moisture-wicking properties. It is also naturally hypoallergenic, making it an excellent choice for those with sensitive skin or allergies. Microfiber Filling: The filling in these pillows is made from 100% microfiber, a synthetic material composed of ultra-fine fibers. Microfiber filling is prized for its plush feel, mimicking the softness and loft of down while being entirely hypoallergenic. It provides a comfortable level of support, cradling the head and neck for a restful night's sleep.
