Britax Marathon - Onyx Booster Car Seat

Recently we bought this carseat for my daughter when she turned 4. I wish I had bought it when she was first born. When my daughter turned 4 we put her into a booster seat like alot of parents, without realizing how dangerous these really are. When we were driving and I realized that her seat was nothing more than raising her height it scared me. She could easily slide out of the seat and after showing me how well she could unbuckle herself I thought that was enough and purchased this seat. There is so much room for her in this seat it's amazing! She's 44 pounds and is 42" tall, and has room to grow. It has lots of padding on the seat, and lots of roominess too. She enjoys being so high up and back in the middle of the backseat so she can see everything. I personally love the fact that it is so snug in the backseat. I drive a Pontiac Grand Prix and found this seat very easy to install (as easy as the others or easier) and doesn't take up as much room as you would think. Still room for 2 more passengers or even 2 more carseats in the back no problem. My only complaint is that there's not an optional cupholder that could be removed so it does make reaching to the backseat a little bit of a pain. Well worth the money.
