This is a protector for Coodie wet sheets. It's a waterproof sheet for use in strollers and car seats. I used it twice in a car seat, but since there were no accidents, I'm selling it. ⚠ Please do not purchase if you are concerned about it being folded up for shipping! Description: Protective sheet to protect the seat from all kinds of dirt! During childcare, you're worried about various stains, such as diaper leaks, accidents during potty training, spilling drinks, and mud. The absorbent terry cloth surface and waterproof backing protect car seats and strollers from dirt! Good news for moms and dads who are nervous about leaks during potty training! If you put down the wet sheet protector, you won't have to worry about urine soaking into the car seat... or the smell of urine not coming out! It can be washed in the washing machine, so it's always clean! Just put it down during long outings, and you can relax anytime! It's great for summer leisure activities, such as when traveling in swimwear!
