Review: Fits 2 in a row with additional infant seat in Toyota Camry! - We bought 2 of these to fit in the backseat of our 2010 Toyota Camry. 1 rear facing, middle forward facing, next to infant (Uppababy Mesa) seat. Middle forward facing was the only way it would fit. Pro’s: slim, sturdy, easy for our kids to get into themselves, latch system is easy/works well. Good customer service from Diono. Our first one didn’t have the rear-facing piece in the box. Cons: * Very heavy! * Tall backside. Check your car seat manual whether a car seat is allowed to touch/rest against the front seat (if rear facing). Now having moved one to the middle back seat (forward facing) on our Honda Odyssey, it sits higher and blocks the rearview a bit. Wasn’t an issue in the Camry. No cupholders- fine, since that wouldn’t fit anyway. Not as much padding, so perhaps less comfortable, but both our kids are fine in them. Overal conclusion: great car seat if you have a tight back seat!
Review: Great for Tight Spaces and Growing Kids - This is an excellent car seat for a growing toddler or child. We loved it so much that we purchased one for every car, including the grandparents’. My son had difficulty getting in and out of his previous car seat and struggled with buckling, but he has completely mastered it with this one. He feels more independent and proud that he can get in and out on his own. Another big plus is how space-conscious this seat is. We can comfortably fit two car seats and a third person in the middle seat of our SUV, which is perfect when traveling with extra passengers. Installation is easy, making it simple to move between different vehicles if needed.

## Questions & Answers

**Q: Can the Radian be rear-facing and still give a tall driver (6 ft) enough room? Or will it fit in the middle without hitting the driver's seat? Mazda3.**
A: Place it behind the passenger side, if you’re shorter.  It you’re 6’ tall, it will be too crowded.  You may try it in the middle, but it may still affect the front passengers.

**Q: How deep does the vehicle seat have to be for rear facing and for forward facing?**
A: This seat is hard to install properly while rear facing because of its height. The angle of the seat has a lot to do with it. We have a rav4 and a Prius the Prius actually fit better because of the streeper seating angle. They sell a foam angle adjuster that does pretty well in the rav4, but if I was much taller (I'm 5'9") it'd be a tight squeeze up front (the car seat is not supposed to touch the seat in front of it.) These are very well made though and much higher quality than many other seats in the same price range. Plus you can fit 3 across in every vehicle. I'd recommend to anyone.

**Q: Fecha de vencimiento?**
A: We ship using UPS ground and normally the item goes out either same day or next day.

**Q: How do I secure on in the middle seat in the back (3 seats across ans forward facing) if I don’t have latch in the middle seat?**
A: If you are unable to attach the seat with the latch system you can secure it with the vehicles seatbelt.
