These are mattresses we designed specifically for young children.  Organic cotton quilted mattress pad is recommended in case of wetness accidents for added protection. The 6" thick option though is perfect for adults or any guest beds!

We take a 4.5" natural rubber core and cover it with our wool puddle pad fabric. This makes a mattress that has no cotton on top at all to get bacteria or urine. It fully protects itself. It is the best for anyone that has a severe dust mite allergy or a mold problem in their home. The wool and the rubber protects from dust mites/bed bugs and from molds. When child gets heavier you can add a 2" topper.
