Summer is great, because there’s so much you can do. Hiking, swimming, camping, you name it. Unfortunately, with summer comes the heart. There are plenty of ways to keep cool while you’re awake, but if you’re like me, your body turns into a small furnace when you go to sleep. Fans and central air can only do so much, but that only gets the area above your covers. Wouldn’t it be great if you could cool the mattress underneath you?

The ChiliPad is a mattress cover that allows you to select the exact temperature you want your bed to be. You can set it to anywhere between 55 and 110 degrees. That’s right, it works as a heater in the winter.� There is a small box that sits next to your bed, and a remote that lets you easily change the temperature without moving. You can buy different pads depending on the size of your bed, but unfortunately they start out at $400. How much is a cool (or warm) bed worth to you?
