  • Fits well beside 2 britax marathons in the same row.
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
We have a Jeep Grand Cherokee and 2 britax Marathon click tight carseats. One is rear facing, the other forward facing and this diono is forward facing as well. It fits great and my 4 year old seems more comfortable even though there is much less padding on this seat compared to the marathons. One thing I don't particularly like is the way it Jenks to the side when I tighten it. I'm not sure if we chose the wrong installation method or what, but it's anchored to the back with the lap belt installation and still Jerks to an uncomfortable degree when I pull the strap. Seems secure otherwise. I think this seat is best for older kids, I wouldn't feel comfortable putting my 1 year old in one of these bc of the lack of padding and support around the head but I knew that when I purchased it, and it's perfect for my 4 year old. It's also WAY easier to buckle and unbundled in comparison to the marathons. I LOVE that about it and the shoulder padding is longer which is nice bc she often complained about the straps digging in on her old seat. ... show more

  • Annoying Installation
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
I randomly decided to downsize from a three-row vehicle to a two-row vehicle, so I needed to find car seats that would fit 3 across comfortably. These car seats definitely work for that. The thing I didn’t like about them is the company’s attempt to save money by not providing any instructions in the box (3 new boxes and absolutely no instructions). There are picture instructions on the side of the car seats, but like most things, these car seats are a little different than other car seats, so more detailed instructions would’ve been appreciated-particularly for rear-facing installation. If they want to save money, maybe they should provide a QR code with links to instructions and videos. They didn’t so I was left trying to find instructions for my exact model. The belts that give you lax for anchoring are also really annoying. Broke a few nails in the process. ... show more

  • Love
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
I purchased this car seat when I didn’t have much back seat space. I was able to fit this car seat into my car unlike a lot of other car seats. I appreciate that it saves on space but still seems quite durable. It does not come with cup holders like most car seats these days, however, I was able to purchase a separate cup holder attachment which has worked great. The seat is easy to install, and my child is much more comfortable in this seat as opposed to some other leading competitor seats. I wish I had bought this seats for both cars! ... show more

  • feels solid very high quality product.
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
We have four kids so we’ve gone thru our share of car seats and boosters, for budgetary reasons we always went with what was the most affordable usually that means plastic and low quality materials that wear out fast. This product is the complete opposite of low quality, it’s solid and strong but very comfortable and my daughter loves it, we needed something that she can grow with, for the past few months she kept moving around and being very wiggly in the car, while cleaning the car I noticed her car seat was wearing out and felt very uncomfortable, this new seat looks great and my daughter is sitting perfectly. ... show more

  • This thing is awesome!
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
I needed a solid upright car seat that was thin and well built, this is the one! I fit it in the back of my g70 which has a very small backseat and there is still plenty of room for my other two children to sit back there comfortably. I loved it so much I bought another for my wife's car, it's extremely well built and it's much nicer looking than the same old (insert other brand here). ... show more

  • Love it.
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
This is great and would definitely fit 3 across. If rear facing and you are tall you won't be able to move your seat back as far as you want, at least not in a Subaru Outback. I am 5'5" and it is fine my husband is 6' and he has to sit more forward than he likes.

  • 3 across in Tesla model 3
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
Exactly what I needed. I have twin 7 year olds and one just under 2. All three fit comfortable in the back of my Tesla model 3 with the twins facing forward and the little one rear facing.

  • This Saved My Son
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
I'll be repurchasing two of these. I got in a car accident yesterday. My son, daughter, and I got T-Boned.. This car seat is so sturdy. My son got the worst out of the hit (He is not injured, he is well.) - and he didn't move out his car seat, fly out.. or anything.. I just unfortunately now have to replace the entire car seat (state laws..) - but I'm pretty sure this car seat is our savior! It's worth the money. ... show more
