About this item 1.【Extra Thick & Luxury Comfort】 Filled with more 3D snow down alternative fill. It’s plusher and fluffier than mattress pad and mattress cover in anti-flattening and provides longer comfort. It provides even pressure and moderate softness to your entire body, thus relieving back pain. 2.【Cooling & Breathable】 The 400TC brushed fabric surface makes it breathable and can absorb sweat. Made of cotton top, breathable and skin-friendly fabric allows air flowing effectively without being too squishy. 3.【Special Quilting Pattern Design】 It keeps down alternative filling in place and prevents fill from shifting or bunching in one area. 4.【21 Inches Elastic Deep Pockets】The thick elastic deep pocket can secure the product firmly to the mattress, prevent it from moving at night and offer you a comfortable night's sleep. 5.【Machine Wash & Easy Care】 Mattress pad can be thrown directly into the washing machine and will be clean and fluffy after washing and drying.(NOTE:please use the large-capacity washing machine)
