This plush, soft pillow is made with microfiber fill, a high quality polyester designed to mimic the properties of down. Microfiber traps less air than down and is a tad denser, so it does provide a bit more support than natural down. One benefit of a synthetic pillow is that it can be machine washed at home, given your machine is quite large and you wash/dry on a low heat setting. Natural down and feather are sensitive to moisture, but polyester is not! Medium Support is a moderately-filled, moderately-filled plush pillow that works well for most sleepers and sleeping positions. It's a crowd-pleaser!
