Body Heat Activated Crib, Twin, Full, Queen or King Size Bed Warmer Mattress Pad (Crib) by Perfectly Safe;

Our Crib & Bed Warmer Mattress Pad is body heat activated based on the principle of the space blanket. Just place in between the mattress & the sheet and its thermo-lining reflects body heat and warms a crib or bed up to 10 degrees above room temperature. Safe and convenient for travel since no electricity is needed. Stain and moisture resistant. Simply wipe clean with mild soap and water. Made in the USA. This warmer does not cover the entire mattress, it is meant to cover the area where the person sleeps, therefore it will be slightly smaller than the mattress. This warmer uses only body heat - once a person lays down their body heat will reflect back up to gently warm them.
