    Great Seat for Small Cars and Multiple Children

    Customer review by kathryn3808

    5.0 stars by kathryn3808

    I have used Britax Marathons for years with my two girls. I love those seats, but we recently sold our Yukon for a Chevrolet Equinox. It gets much better gas mileage but is considerably smaller. There was no way to fit both our seats and another person in the back seat so we got two Radians. It is a little tight, but with both Radians in the back seat a third person or third car seat will fit. I like the fact that is converts to a booster when we are ready. I will say I have owned several car seats over the years and these were by far the hardest to install. I think this was in part to the short tether strap adjustment and the fact that our read headrests are unmoveable. We also have some generic seat protectors that we have used under all our other seats. We had to get rid of those in order to get a good fit for the seats. Both my girls are comfortable in these seats and like how low they are compared to the Britax. Overall, if you have the room, I still beleive the Britax Marathon is a better seat, but if you need space this is still a good solid seat. It does have several similar features of the Britax. I miss the ease of use for adjusting the straps on the Britax. Both my children are forward facing, so I cannot speak to the rear facing options for this seat. I would recommend this seat to anyone with more than one car seat in the car and/or who drive small and midsize vehicles.

    After a lot of research, we chose the Diono Radian R100 for our youngest child when she was on the verge of outgrowing her infant carseat. This seat is well made with good quality fabric and sturdy construction. It has excellent safety ratings, is narrow enough to sit 3 across the backseat, and folds flat for storage! We are quite pleased with it and definitely think the price is worth it for the quality and lifespan of use--our daughter will be able to use this until she doesn't need a carseat anymore! We highly recommend it!

    A little tricky to install - I definitely had to read the manual. But once I got it in, it was great. I needed to fit 3 carseats across the backseat of our Malibu and this was perfect. I was able to fit this, a booster, and an infant seat with no problem.
