The Zen Bamboo Ultra Soft Bamboo Mattress Topper is a must-have for any sleeper seeking the ultimate in comfort and luxury. Our fitted mattress pad is overfilled with a down alternative fiber blend and stitched with a double-needle baffle box which prevents fill from shifting and ensures a balanced, pillow-top sleeping surface. The select blend of soft microfiber and natural rayon from bamboo on the Zen Bamboo Mattress Topper has a soft, silky hand feel and also promotes temperature regulation by preventing heat from being trapped between the body and the mattress. Our topper has a strong elastic skirt, and will fit most mattresses up to 18 inches in depth.
