We start with a 6″ natural rubber core which is then covered with our untreated, natural wool moisture resistant fabric which is the same natural fabric we use for our moisture resistant pads. This natural wool outer will help to repel liquids, keeping the natural rubber core in good shape. Because wool is a natural fire-retardant, we do not use any fire-retardant chemicals in or on this mattress.
Order this item if you need any custom size up to 28x52x6″ (standard size crib mattress). If you need a size significantly larger than this, please contact us for a quote.
