Pure comfort. Purely organic. Luxurious organic wool is wrapped in an organic cotton casing. The wool will help to regulate body temperature for a deeper night of sleep. Utilizing a mattress topper also helps relieve pressure points. The wool is shorn from Corriedale sheep. Their wool is extremely resilient, dense, and fluffy with an extremely comfortable feel that keeps its bounce and cloud-like feel for years. These sheep graze in pastures that have not been treated with pesticides or herbicides. The wool is washed with hot water and organic soap. This process allows the wool fiber to retain two to four percent of its lanolin oil – a natural dust mite repellant. The cotton making up the casing is GOTS-certified; the wool is completely organic, including the way it is processed. You can rest easy, knowing that you are sleeping on the purest of materials.
