Memory foam mattresses are great, but they do have their drawbacks — lack of bounce, heat retention, sinkage. The Casper Mattress manages to give you nearly all of the benefits of memory foam without the drawbacks. Designed to conform to your body without sinking, the Casper is topped with a layer of high performance latex foam that provides air circulation and bounce, with a plush layer of memory foam underneath that still cradles your body like a cloud. In addition, it's made in the USA, comes packed in an easily-maneuvered box — no more lugging awkwardly flopping rectangles upstairs — and actually costs less than you'd expect. Win, win, win.
Let's face it, monitoring your weight — no matter how carefully you do it — just isn't enough information to keep you in touch with the healthiness of your body. With the Withings Smart Body Analyzer ($150) you get much more data than you could ever get from a standard scale, all housed within a familiar-looking device. Sure, it measures your weight, but it also calculates body fat, resting heart rate, and indoor air quality. Additionally, all that data gets synced automatically with your mobile device using the Withings app for iOS. Using this data, you can track your progress, and get smarter about the way you manage your body.
