PeapodMats are simply amazing and versatile waterproof covers that are unlike any conventional waterproof covers on the market today! PeapodMats are designed to protect the bed from all sorts of fluids. The difference with this one? It lies flat ON TOP of sheets with a grippy material underneath that means no more bunching, moving or tucking. PeapodMats are comfortable and soft to sleep on with no plastic crinkle sound or cold vinyl feel. Though mattress/sheet protectors made from plastic can also prevent liquids from going through to the mattress, the liquid saturates the sheets being slept on. More than likely you may have to clean up the mess using a few towels, and then have to strip and change your bed sheets. However, with any accident on the waterproof PeapodMat, the only thing you would need to toss in the wash is the PeapodMat itself. Kind of like washing your super amazing towel! PeadpodMat dimensions: 3x5 (.914m x 1.52m).
