The branded luxury trend gets even bigger and much, much younger with the BMW Sauber F1 baby seat. And what would such a baby seat be without some BMW engineering? The side bolsters move in relation to the seat height, which means the seat "grows" with the child. If only your kid's shoes did the same. It doesn't have side airbags, but it does have a belt carrier, and it's good for from 33 to 79 pounds, or 3.5 to 12 years old. Thankfully, it looks way more comfortable than an actual F1 bucket, and imagine being able to tell your friends that you got your first F1 seat when you were three.
