This 100% cotton mattress pad provides a comfortable night's sleep with non-slip features. Unlike traditional pads with corner rubber bands, this one has a non-slip treatment, so you can simply place it on your bed. - Type: Mattress Pad - Size: Semi-double SD 120-200cm - Surface Material: 100% Cotton - Backing Material: 100% Polyester - Filling: Kapok 55%, Polyester 45% - Features: Non-slip treatment About Kapok: It's very light. It's said to be one of the lightest natural fibers in the world, weighing only about 1/8th of cotton. It also absorbs moisture and helps retain warmth in the cold, and releases moisture to maintain a comfortable state in the heat. I purchased this last year and have stored it in the closet. In my personal opinion, the texture feels nice. The original purchase price was 4990 yen.
