Query: Fantastic Accident-Proof Mattress Pad

I purchased two of these waterproof mattress pads for my son's bunk bed. He has frequent night-time accidents, and these work perfectly at protecting the mattress! Easy to wash and to install. They fit snugly and are quite comfortable as well. They are also very queit, as the protective barrier is sandwiched between two padded layers (no plastic rustling sounds!) It also adds a little extra padding to the mattress, adding to the comfort. I highly recommend these mattress pads for your kids' beds to protect your mattress and its warranty.
