Abstract: A portable and foldable toilet seat is disclosed which comprises a thin shell having curved edges which snugly fits over the top of a permanent toilet seat to prevent slippage and includes a stack of disposable liners within said shell. After use, the liner in contact with the permanent toilet seat is peeled away from the stack of liners and appropriately disposed of. The seat may then be folded into a compact quarter oval shape devoid of any contamination from the permanent toilet seat.
