## Questions & Answers

**Q: How wide is the seat between the arm rests?  My child has wide hips and I want to make sure he fits.**
A: 14” near the back and it opens to 15” near where the hands rest. My 5yo wears a boys size 10 or Medium and he’s comfortable in the seat.

**Q: What’s the narrowest it will go?**
A: Can you be a little more specific? 
The adjustable sides expand from approximately 18" - 22" in the shoulder width.  The bottom portion measures 15" in the back. Hope this answers your question.

**Q: Would this fit to my 3 years old one? He’s about 40 lbs**
A: No. A 40 lb 3 year old should be rear facing in a convertible 5 point harness (even if their feet touches the seat) as its 5 times safer.  I would look at the Diono Radian. Boosters start around 6 for average size kids or maybe 5 for a very large child. If rear facing is not possible he should be forward facing in a 5 point harness.

**Q: Does this seat have a tether to attach to car?**
A: Yes, it has the Latch System.  You see the 2 straps sticking out of the front?  Those are to tighten the straps(tether).  There are 2 hooks that can attach to something from the base.  I don't have the Latch System in my truck, but I was able to fastened the hooks to the frame.  They say they aren't necessary, but they keep the seat in place.  The best way to see this, is to go on youtube and search the seat.  There is a good video on there to show how to install.  I think there is one on their website too.  The pictures and descriptions on Amazon aren't always sufficient.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits Volvo XC60 and XC90, great for tall kids!
*by K***. on April 30, 2025*

I do wish the limits of the Diono seats with extra protection were as high as this one, but I’m glad they have something that goes to such high height limits, and this still has very good safety features beyond the requirements. Our son is very tall and I was glad to find a seat he could use for such a long time. We’ve had this over a year now—two of these actually, and the quality has been very good. My son also finds the seat very comfortable. We have two extremely hard to fit vehicles—Volvo 2012 XC60 and 2013 XC90, and this seat actually fits and works with the non-removable headrests and jut forward. These are a very good value for the money because of the high height and weight limits. Glad to have found these.

### ⭐⭐⭐⭐⭐ Perfect low profile children's booster seat.
*by S***. on June 12, 2024*

This was a great cost effective choice for us in our 2024 Nissan Pathfinder. We were looking for something with a smaller profile in the captains chairs so the 3rd row was still accessible. I did a lot of research to find something that was capable of fitting our needs and also being safe for our girls, and this seat definitely fit all of our needs. This was a recommended buy from consumer reports with recommended great performance. With the built in latch anchors in the front the installation is very easy. It allows the seat to feel secure and stable while using the cars seat belt. It has dual cup holders that fold away. The material is nice and soft and seems like cleaning will be very easy. Overall we would definitely recommend.

### ⭐⭐⭐⭐⭐ Great seat for bigger kids!
*by P***Y on June 18, 2025*

Works great for my big 6 year old who outgrew another convertible high back booster seat. Super easy to put together and install, and my daughter loves it.
