Mattress pads are used for a variety of reasons- warmth, comfort or simply to give a new lease of life to an older mattress. Our organic mattress pad also brings you the reassurance of sleeping on completely pure untreated materials. Organic wool is covered by a 100% organic cotton cover- no chemicals and no pesticide residues! All mattress pads can be made to any shape or size and additional layers of wool can be added to suit personal preference.
