EBayAller-Ease Ultimate Cotton King Mattress Protector Maximum Allergy & Bed Bug Protection with Premium Cotton Comfort Upgrade your sleep environment with the Ultimate—the top-tier model in the lineup. Unlike basic protectors that feel like plastic, this "Ultimate" version is designed for those who want heavy-duty protection without sacrificing the feel of their high-end mattress. The "Ultimate" Difference (Why Choose This Model?): 100% Cotton Top: Most waterproof protectors use polyester, which can feel hot and "crinkly."
