Product Description: This layer of ultra-soft Microfiber fill offers the time-tested comfort of traditional downing without any of the associated odors or sharp quills that usually accompany down; and with a thickness of 5 cm, it is more comfortable than usual mattress toppers. With a soft and breathable 250 thread count, 100% cotton percale cover envelopes the topper in a comfortable and durable package, it is also machine washable and dryer safe (on low) for easy cleanup and continued freshness. It is made with box stitching that helps maintain loft and improve breathability by keeping fill distribution in even uniform pockets and prevents fill from shifting or bunching in one area, even when used and washed plenty of times. It is equipped with elastic straps that are positioned on each corner to securely attach the topper to the mattress, preventing the topper from shifting at night and providing consistent comfort.
