User questions & answers

Question:	does it come with the arms off? We don't use them and typically don't install them
Answer:	Hello, our Solana backless booster seat does not come in parts, as it is one complete booster seat. The "armrest" are not only for comfort, but are guides to help place the seat belt properly low on the pelvic bones, a proper fit for a child.
Question:	Which dimension is the width
Answer:	The total width is approximately 22.5" with the cup holders out. The back portion is approximately 16.5"
Question:	How does this differ from the original
Answer:	It is specifically made for "big" kids....the ones who are to big/old for a regular booster seat, but not quite tall enough for the seat belt to fit correctly over the chest. This booster allows for the belt to fit correctly. I bought and use it for my 10 yr old granddaughter
Question:	Can the cup holders be removed
Answer:	Hello. The cup holders cannot be removed. They swivel in and out, though if you are trying to make more room.

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.

User questions & answers

Question:	What about mazda cx5? i'm waiting my third child and need to find a solution asap. thank you
Answer:	Hello, you will need approximately 54" of space to fit three across forward-facing. The bottom portion of the Radian is 15" so with it rear-facing and two forward facing there may be a possibility. The top portion is 17" across the top at its widest point.
Question:	Would this work well rear facing in a 2 door car
Answer:	This product takes up 32-36" depending on the vehicle seat pitch in the back seat. If your child has full head control, the addition of our Angle Adjuster may work best for you. While 2 door cars can be challenging with any car seat, this one is slimmer than most on the market and has low boarding sides.
Question:	Hello! will this fit 3 across in a volvo xc 90 or any suv
Answer:	Yes
Question:	will 3 of these fit in a Chevy hhr
Answer:	I think so

User questions & answers

Answer:	Hello, this is a convertible style car seat which is meant to stay in the car. If looking for a carrier, search for the term infant car seat, infant car seat travel system or rear facing only car seat.
Question:	Looks like there is no head or hip protection for side impact. Without side wings and being so shallow how will this "cocoon" them on impact
Answer:	All Diono car seats are crash tested to meet Federal Motor Vehicle Safety Standards. Several seats are also crash tested annually by the National Highway Traffic Safety Administration at a certified crash testing lab. In addition to ongoing crash testing to ensure our seats meet regulatory safety standards, Diono continues to rely on customer feedback. The Radian series has 6+ years of customer use with positive user experiences. We believe everyday customer use, including real-life crashes are an extremely important indicator that our seats are safe. Based on field data and consumer feedback, there has been no indication of a severe side impact injury or deficiency in side impact performance with the Radian models. In reviewing safe use of car seats, we also recommend checking the NHTSA safety recommendations as well as your state requirements.

User questions & answers

Question:	Can the seat recline at all in the forward-facing position
Answer:	The car seat doesn’t recline at all (however it does allow for a folded option when traveling) but it doesn’t recline. The seat back is pretty vertical compared to other brands, but my toddler hasn’t complained at all. To avoid their heads falling forward when asleep, there’s a soft strap that helps keep their head in place, but I haven’t needed it yet.
Question:	How is torso height measured
Answer:	I don't know officially, but I would assume measuring from the base of the neck of the child to the groin area. I do know that Diono has a pretty extensive tools/videos on their website that we utilized before we purchased. the might have instructions on how to measure torso height. Also, I found this website as well https://csftl.org/car-seat-basics-measure-child/ I hope that's helpful.
Question:	What is the overall depth of the seat when in Rear Facing Mode and how much does the angle adjuster reduce the overall depth
Answer:	Hello, when the Radian is rear-facing it takes up approximately 32"-36" from the vehicle seat back to top of car seat shell. It will depend on the vehicle seat pitch. The Angle Adjuster helps the car seat sit more upright approximately 4" to give front seat passengers more room. Keep in mind, your child needs full head control to use the Angle Adjuster.
Question:	Anyone used this for special needs low tone older child
Answer:	Hello, depending on the needs of your child, you may want to select the Radian 3RXT because it has a head support. You can also use it to 45 lbs. rear-facing. Many parents have used this car seat for children with special needs. I hope this answers your question.
