Microfiber has been around for a long time. It is only just recently that microfiber pillows are gaining popularity because they are very affordable and easy to clean. This kind of pillows is usually made from polyester and nylon. Each strand of microfiber is thinner than a human hair or a thread of silk.
They provide soft and comfortable insulation in comforters and blankets and down-like softness and compression in pillows. Machine washable and hypoallergenic, microfiber fills have quickly become the industry's insulation of choice for upscale comforters, pillows and mattress pads.
