Snug Fit %26 No Plastic Noise

Ordered a couple of these to protect new bunked bed mattresses, and they fit snug and secure without slipping or bunching up at the corners. The material is plastic looking but it's not loud and holds up nicer than expected. It does a great job guarding against everyday spills and moisture, giving total peace of mind. It's also super easy to wash and holds its shape well in the laundry. Excellent, affordable value for keeping a mattress in top shape!
