Serta-Plush Heated Mattress Pad works so nicely at keeping me warm throughout the night. This mattress pad was so easy to assemble. I simply washed it,placed correctly on my bed. I plugged in and then set the control to my desired number and temp and drifted off into a peaceful slumber.The warm mattress pad is soft and the plush feels very nice and comfortable. I am so excited to have a Serta Plush Heated Mattress Pad and absolutely will be purchasing as gifts.
