Micro Flannels luxurious softness and warmth properties are married to soft wire warming technology to create the perfect heated mattress pad. Micro Flannel naturally retains and reflects a portion of body heat, does not shrink, does not pill and resists wrinkling for long wear. Our Micro Flannel heated mattress pad is made by adding a layer of quilted down alternative fiber to the underside of the Micro Flannel face fabric. Soft wire heating technology developed especially for mattress pads is layered in underneath that down like fiber. Additional layers of insulating fabric enclose the heat source and a layer of Micro Flannel fabric is added to the back. All is quilted together with tac-tite stitching so there is no shifting. The gentle heat rises through the Micro Flannel fabric which helps to cycle a portion back to the user. This creates a soft environment of overall warmth; not too much, not too little- a complete and gentle comfort enivorment. This mattress pad has extra deep pockets to fit mattresses up to 18 in. It has Easy to Read and Easy to Use controllers with large back-lit numbers. There are 8 secure heat settings, 10 hours auto shut-off and extra-long 16 ft. cords for your comfort. The Micro Flannel heated mattress pad is machine wash and dry, ETL Tested and approved and has a 5 year warranty. Snuggle up for a good night's rest.
