Our Organic Mattress Pad Protector is certified organic by GOTS. It's handmade with 400 thread-count organic cotton ticking that is elegantly quilted over absorbent, breathable organic wool, certified to the Responsible Wool Standard. It features a gentle-fit organic cotton pocket and an elastic perimeter in a natural ivory color. Because organic wool absorbs more moisture than cotton without feeling wet, it enhances breathability and helps deliver cool, natural sleep. It adds protection and a touch of luxury without waterproofing. For our Organic Luxury Plush and Ultra Plush Mattresses, the Deep Pocket version is required. It pairs beautifully with our Quilted Pillow Protector.
