I just discovered a new protective sheet for the bed. I purchased a PEVA shower curtain from Walmart. It's made by Better Homes and Gardens. It's 70 inches wide and 72 inches long. I have a queen bed and it fits it perfectly. It's made of a real thick clear plastic. The only drawback is that it makes a loud crinkling sound. I personally don't have a problem with it (I'm a deep sleeper) but other people might. I like thick plastic covers because they last longer. I thought I'd mention this in case people were looking for alternative ways to protect their bed. I know many people use shower curtains to protect their bed from bedwetting.
