User questions & answers

Question: How wide is this seat at its widest point
Answer: The widest point is near the top of the shell and it is 17". Hope this is helpful.
Question: Can you remove the small red metal bar on the sides of the car seat

Question: Does the 3R have head support/head wings like the 3rxt
Answer: Hello, the Radian 3 RXT, Rainier 2AXT are the only convertibles with the head support. The 3R does not have adjustable head support.
Question: Is the measurement given, the most narrow part of the seat or the widest
Answer: The widest part of the seat is 17" towards the top portion of the car seat.

User questions & answers

Question: How deep does the vehicle seat have to be for rear facing and for forward facing
Answer: 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.
Question: Is there a seatbelt positioning system as a high back booster seat or do you have to wait until they reach a certain height
Answer: The red "hooks" you see at the top of the seat are vehicle seat belt guides that you use in booster mode.
Question: Can you fit 3 wide in the rear row of 2010 cadillac escalade esv
Answer: You can fit this seat 3 across in most standard size vehicles, in order to fit 3 of the Radian models across in any vehicle you need 51 inches or more of space.
Question: 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? Mazda
Answer: 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.
