There are two things guaranteed in life: taxes, and accidentally staining your mattress. That said, when the accident happens, our mattress protector takes charge. The Pr1me® Terry mattress protector features a hypoallergenic and absorbent cotton terry surface that sleeps comfortably and will not change the feel of your mattress. It also features the laboratory-certified H2Pro® liquid-proof membrane which creates a quiet, and breathable barrier against allergens and dust mites. The universal fit elastic perimeter ensures a secure fit for mattress depths of 6″-22″.
