Non-Electric Aqua Bed Warmer - Hot Water Bottle Heating Blanket for Cold Nights | Perfect for Winter Warmth, Pain Relief & Cozy Sleep

The assisted living facility for my mom absolutely forbids electric blankets and heating pads-as a fire issue because the wires get bent in these items and can break. I asked ahead of buying this if it would qualify to be used by my 93 yr old mom, who is always cold. YES, it doesn't heat with wires throughout the cloth part of the pad. Instead there are silicone channels throughout, and lumpiness was not an issue. I positioned the connector at the head of the bed, dropping the water lines under the headboard (they don't touch it) and out to the side to the heating unit on the night stand. It warms very quickly, I'd say less than 5 minutes. Mom is able to remember to push the center button, which is all that is required, to turn it on, and it just warms for 10 hours until it turns itself off. I'm very pleased with the fact it covers the ENTIRE full mattress, and has corner elastics to stretch under the corners of the mattress, to hold it in place. I put a thin, bamboo mattress pad over it (which breathes but is moisture resistent in case of accidents). Mom loves it, and I know she sleeps better feeling warm. She also likes that it is comforting to her tailbone and back which are extremely boney and arthritic.
