Hotel rooms get this right: the bed looks structured, the surface is cool to the touch, and nothing shifts when you sit down. This five-piece set is built to reproduce that. The duvet cover and shams are 500 thread count 100% cotton sateen, embroidered with a double-row stripe, so the sheen comes from the weave rather than a finish that washes out. Inside sits a removable comforter insert — 100% polyester microfiber with down-alternative fibre fill — fluffy but light, warm without the weight of a heavy duvet. A zipper closure, four corner ties and matching corner loops keep it precisely in place, so the cover does not migrate to one end overnight. King/Cal King sizing runs 108″ × 96″ for the cover and 110″ × 98″ for the insert, with two 20″ × 36″ shams and a 12″ × 16″ throw pillow. OEKO-TEX certified; machine wash cold, gentle, tumble dry low, no bleach, no iron.
