The sleep surface is treated with an embossed process, which is usually applied to sports fabrics, making it more breathable and stylish than ordinary material and bringing an advanced dynamic vibe to your bedroom. - ULTRA SOFT FLUFFY - We use 120gsm thick brushed microfiber as the sleep surface. Overfilled with 12oz 5D spiral fiber, thicker than most on the market. The fiberfill maintains excellent softness and resilience, making this mattress pad super fluffy. Let you enjoy the luxury hotel level of comfort at home. - UNIQUE 3-ZONE DESIGN - This mattress pad is ergonomically designed with three zones. The head and foot areas use a wavy design, which can ensure the edge is not deformed. The body area in the middle uses cloud-shaped quilting design to provide a larger body supportive area that disperses the body's pressure and prevents sagging. It helps to keep your body stretched naturally for deep and relaxed sleep. - DEEP POCKET EASY CARE - Quilted Stretch-to-Fit (8"-21"): knitted skirt pocket stretches up to 21 inches deep and can be easily placed on most mattresses. The 1.6-inch width of high-quality sport elastic trim securely holds your wrap in place, and its excellent elasticity makes the wrap easy to fit and remove. It ensures you get the most restful and restorative sleep. Machine wash cold, do not use bleach, tumble dry low. - SATISFACTION PROMISE - SLEEP ZONE has more than 40 years' experience in the design and manufacture of high-quality bedding.
