My husband and I are very pleased with this Serta Plush Polyester Heated Mattress Pad. It came just earlier then expected.  The instructions read to put the connectors at the bottom of the bed and the controllers as you can see reached just fine at the top of the bed. It has multiple levels of heat and I can do my side higher and it won’t affect the other side. Can’t wait for cold weather to really get the use of this Serta Heat Pad.
