As winter coming, the weather is getting colder day by day. This year it’s predicted gonna more severe weather conditions so I’m glad that I got this Serta heated pad cover for my kids. The pad heats up pretty up, approximately 15 mins. So I always turn it on before the kids going to bed. The pad comes with a controller to adjust the heat from 1 to 10 and timer runs up to 12 hours. I have tried from the lowest to the maximum heat and recognize that the pad is a little bit too thick so the heat isn’t strong or intense. It’s kind more like warm so I keep it around 8 for the kids. From 1 to 5 is too low that it barely feels anything. Overall, it’s a nice accessory for cool nights so that the kids can have a better sleep.
