Strong sleep on a cloud of 24 ounces of filling and help. The heavenly microfiber mattress pad/topper from Hospitality is made with brushed microfiber polyester, a remarkable fabric that combines the softness of natural fibers like cotton with the durability and hypoallergenic qualities of polyester. The shell fabric has natural stain-repellent properties that can offer short-term protection from minor spills (though heavier spills require professional cleaning). The filling used in this duvet insert is a 100% polyester down alternative, which provides great warmth and hypoallergenic properties with minimal bulk. This high-tech filling also provides excellent temperature-regulating characteristics, getting you right into your comfort zone for an unparalleled sleep experience. This pad/topper is super plush, with an industry-leading 24 oz/yd2 filling. Use this pad on any mattress to instantly create a luxurious pillow-top sleep surface. The dual-stretch side panels wrap around your mattress like a fitted sheet and can accommodate a mattress thickness of up to 18 inches. This product is machine washable but can be too large for some home washing machines. Do not wash in a small machine, which can damage your product.
