    Love It and it fits 3 car seats across!!!

    Customer review by NY205

    4.0 stars by NY205

    This is a great car seat very narrow. I bought this car seat for my 3year old, so we can fit 3 car seats across in my 2005 Rava 4. The 7 year old is in a boster seat, 3 year old in Diono, the baby will be in a Graco infant seat . We put all three in and it just fits!!!! Only reason I didn't rate this a 5 Star, is the seat belt is not as tight as other brands ( Britax, Graco, Evenflow) and I wish it would also recline back more for when my 3 year old is naping in the car. This car seat SAVED us from buying a new car. THANK YOU DIONO!!!

    5.0 stars by Notaregulartoyourstores

    We purchased this seat after it was highly praised in a European Car Magazine article. It was touted as being able to spare one the all to often necessity and embarassment of having to become a Minivan owner/driver due to having three children. This seat is suppossed to be able to fit three comfortably across the back seat of a midsize sedan. I'd bet it can, because it allows us to fit two in the back seat of our VW New Beetle (first generation, not the now overgrown PT cruiser/VW Beetle looking hybrid it has grown to become). And if your saying all car seats can do that, not without having to adjust the front seats forward to avoid being kicked in the back by your little ones. Our first child is in the 97%tile for height for a two year old, and he can't kick us that way anymore. An additional bonus, we were used to having to reach behind the restraint to properly tighten the belts, not with this seat. This seat is so easy to tighten the adjustment straps, I'd bet a feeble 90 year old with a broken wrist could still properly tighten the belts. If you read and follow the directions supplied with the restraint, it will work as it is suppossed to and do it easily.

    I'd read reviews about the difficulty people had installing this product. Diono has a wonderful website with various videos to really help guide those of us who find reading installation manuals less than enjoyable. The car seat itself is sturdy and definitely comfier than our Graco Snugride 35 which was great until my 14-month old grew to 28" and 27 lbs. This Diono car seat is her next rear-facing option. So far, so good.
