If you love that crisp, cool feel of a freshly pressed button-down, this comforter set brings the same clean comfort to your bed. The shell is made from 100% tight-weave percale cotton, designed to feel light and breathable, especially for hot sleepers. On the bed, it delivers a polished, hotel-inspired look with a unique surface texture. The comforter face features four inch vertical channel stitching and a two inch flange detail, and the fabric is designed to soften with every wash while keeping its signature crisp appearance (especially when ironed). Inside, 220 GSM of 100% polyester fiber fill adds year-round comfort without feeling heavy. It is also OEKO-TEX Standard 100 certified (certificate 14.HIN.38767, as certified by Hohenstein), so you can feel good about how it is made. At Mattress Firm, we make sleep easy.
