They make cotton and natural rubber mattresses and will kill you with how good they are:
1# We start with US milled organic cotton fabric and quilt it to 100% organic cotton wool batting.
2# Then we place 3 layers (for rubber mattress) or 4 layers (non latex) of organic cotton batting grown and milled in the USA, on a 1440 steel 660 count coil foundation... [the list goes on...]
