We offer a longer center buckle as a backup option if needed, as well.

What is the country where does this product ach is this made in?

It is designed in the USA and manufactured in China by our company.

It is the seat pad that has a difference from the R series. My son was uncomfortable during those and I wondered if the padding on this model is different. ?

Your right. Yes. I agree. Under the covers in our R series seats, memory foam sits inside the covers, whereas on this seat it rests on the cushion.

A seat that looks like a dream come true
5/5

My name is Julia, and I have taken over 400 car seat classes and installed hundreds of car seats for cars and other car models. One of these Diono seats is a tank. This product requires a few small trades to set up. It is not easy to install. I received a Safe Install with CPST certification when pregnant and on vacation in Florida in the summer, where there is a high amount of heat. However, this chair might not fit best in the car with someone unfamiliar with installing child safety seats (and especially those of you who switch cars from Since my son's birth, I have driven a 2016 Honda Civic with a Diono Randian RXT installed in the middle. To best utilize my back seat, I wanted a slim seat that would last as long as the baby or booster does. And Diono had this. As a former RXT owner I really wanted to buy a new QXT seat because I felt it would put an end to some of the issues I was having. Protection against side impacts- The most difficult to avoid. In order to mitigate the effects of side impact, this seat's shell has been designed for greater protection than its predecessors. In my rear passenger seat, we have an incredibly comfortable experience with our newborn.
Anti- Bars for the comeback. Those older Dionos have straps attached to the front passenger tracks; at night you are able to minimize rotation, but straps can be prone to falling away and dropping off in a crash. The anti- Unfortunately, I cannot completely remove the rebound bar because my car's seats design allows it to not completely brace against the seat despite its stated replacement. Although this changes some crash rotation, it doesn't significantly decrease it. When and how to use them as they are born. The RXT worked great at home from birth, but I couldn't recommend it to babies under 6 months. QXT offers numerous newborn features that make it ideal to keep a new baby up high and to prevent him from flopping around like all the other models on the market. Foot attachments that move forward-in facing foot attachment- I have learned some vehicles don’t have adequate cracks for the foot attachment at the bottom to slip into as needed for achieving the correct angle. For this to be attached to your car, the foot attachment must land on the back seat’s cracking. I’m pretty hard to get seats installed on my mother’s Subaru because they are unsafe to lift up. I bought the Chicco nextfit from this site because you can easily install spare seats on her car. There has been no fix to this issue in the new QXT. I would say that this seat has been quite effective so far. Whenever I have my toddler on my lap, she always reacts well to my older RXT, so I always expect nothing less with this new series of machines. My small automobile allows me to have both sons in its rear seats, which is invaluable if my kids have plenty of use of my rear seat on their heads. Besides its mandatory safety testing, this seat has passed numerous additional tests and will keep up well if rolled over. You should ensure that your vehicle is compatible prior to installing the device. Look on the Internet for videos and read the manual before attempting the installation.

It's my experience that, as of today, you couldn't find a better product than this
5/5

The child seats I have purchased are one for each grandchild, and the replacement ones were bought after a vehicle accident. If you are a trauma nurse, this is the seat for you. I found myself on the wrong side of two of these cases because of the treatment I offered to those kids. You should want to make sure that energy that comes from accidents ends up somewhere, this seat helps absorb it and protects your loved ones.

The installation cannot be done
3/5

Our vehicles alone will cost us $630 for three of these overpriced monstrosities. The wife insisted on taking her parents to check them out. Installation is a pain, especially for smaller vehicles, since each weighs 50 pounds. Our situation dictates that I would need to take these out and reinstall them three or four times a year - but they could be used without installing a new computer. This is something I am absolutely not interested in. My weekend weekend included two evenings of over $1000 (total for 3). They take up valuable time and I can expect to lose even more time when I am forced to uninstall and reinstall them. Since I have been spending four hours each day on this task (consistently), I have three works in place, including one that I gave up on installing (for now). As soon as my kids grow up, these items will keep haunting me until they have died away. Although it appears that the box is full of trendy hashtag, I guess this is all for the best.

What a great seat! But make sure to purchase new ones
5/5

This car seat was very attractive to my family and I. In order to update my wife’s vehicle, I fitted the 3rxT with grandma’s car so she could use it and she really enjoys it. We won't use right-now, because the infant stuff isn't fit for the baby's age range, but the top side head protection adjusts comfortably for infants growing up. This feature was very useful because the added bar prevented the rear facing from falling backwards at any time. The bad: The lack of transparency. I placed the order on Amazon for the open box warehouse deal, as new I believe, as the majority of the time, we always find it to be good value. The item was at 5%, so it was covered by that. stained cloth, a scratched back (such as removing it on concrete), crumbs, and other food piled up inside the seat, there was a very slight tear behind it. In that case, the warehouse did not consider the product to be properly inspected, or refunded or not given the item's proper inspection title. Because as long as it was considered " usable", this car seat wasn't worth just $30 less. After it had sprouted, I would not have had a chance to remove the coverlet in question and wash it. The hassle of shipping and waiting for a return is less frustrating when you can simply order this new item.

The harness adjuster straps do not appear anywhere near in any of the pictures or will not do their part
3/5

It appears that there is not a harness adjustment strap on the car seat. When I look at the design, it's terrible and ugly, thus why this company would employ such an unattractive and unattractive employee. On top of this, it is too difficult to adjust the straps properly. According to the manual, loosen the harness when pulling on the harness adjustment knob. This mechanism does not work as designed. An unusable unit might be caused by a defect or the design may simply be defective.
