• Mattress protector made with a 300-thread count cotton cover, providing a breathable surface and helping to prevent sweating and excess heat during rest. • Thick 100% microfiber filling, offering soft and comfortable support, promoting a restful sleep. • Quilted box design that keeps the filling evenly distributed, increasing fluffiness and preventing the fiber from shifting. • Does not generate noise or discomfort when moving during the night, providing a more pleasant sleeping experience. • 38.1 cm elastic skirt that fits completely around the mattress, suitable for mattresses from 20.3 to 45.7 cm deep, ensuring the protector stays in place. • Easy care: machine washable in cold water on a gentle cycle and tumble dry on low heat or air dry. No ironing required. • The mattress topper is delivered vacuum-packed; after opening, it is recommended to let it rest for a few days or wash and dry it so it regains its thickness and fluffiness.
