The Tempur-Pedic Cool Tot is a technical mattress protector designed for infant and toddler beds. It serves as a high-performance moisture barrier that fits snugly over a 52-by-28-inch mattress. The top surface uses a polyester blend treated with a phase-change finish to help manage surface temperature, while the underlying TPU membrane blocks liquids from penetrating the mattress.
A primary benefit of this design is its acoustic neutrality; the materials are bonded to prevent the "plastic" noise common in cheaper vinyl covers, which helps avoid waking sensitive sleepers. The deep-pocket design and heavy-duty perimeter elastic are practical safety features that prevent the protector from bunching or sliding off the corners. The TPU membrane is microporous, which helps with vapor permeability while still maintaining its waterproof integrity.
To maintain the durability of the waterproof seal, it is important to dry the protector on a low heat or air-fluff setting, as high temperatures can damage the membrane. While the material is designed to dissipate heat, it is not an active cooling device and will eventually reach body temperature. It is a robust utility item for parents who want a silent, secure, and waterproof layer for their child's bed.
If you are looking for a thicker foam topper to change the firmness of the bed rather than just a protector, the Modera 2-inch memory foam topper is a suitable alternative.
