Love the yellow color but shocked that the cup holders are too narrow!

Just received and installed our Monterey 4 DXT in Yellow Sulphur. The color is bright and vibrant which made my kid happy. It took only a few minutes to read the instructions and install the seat via Latch.

Hopefully we will never have to experience how safe they say this seat is. So I can't speak to that for now.

So far, the oRead more about review stating Love the yellow color but shocked that the cup holders are too narrow!nly downside we've discovered is that the seat is wider than expected. My 6yo has a hard time reaching around the wings to the seat belt insert which is flush up against the side at the back of the seat bottom in our VW wagon. The width of the seat nearly covers the seat belt insert.

The cup holders that pull out are also too wide and we can't pull the holder out on the door side. In fact the cup holders are too small and do not fit our Hydroflask or Kleen Kanteen bottles! Forget about the bottles with the extra silicon base. This was shocking since most stainless steel bottles on the market are near identical in diameter. Furthermore, we can't use the cup holder in our car's center fold-down armrest either because then my kid can't unbuckle their seat belt. The Diono seat is just too wide and doesn't leave a gap.

Overall it seems like this car seat will do better in bigger car. And Diono should consider increasing the diameter of the cup holders at least a 1/8" to accommodate standard little & big kid sized bottles (vs. smaller toddler bottles.) I'm about to write to them about this - it's a big issue for pretty standard equipment on car seats. And this model is brand new so it's not like water bottles have changed in the last few months. Truly surprised by this oversight.

wide seat capacity at an age appropriate buckling ability.

Lots of room for a growing 5yo boy who wears size 7-8 clothes.

Only car seat brand I’ll ever buy

I love our Diono seats. We’ve had multiple styles since my oldest was out of a carrier. They are comfortable, easy to clean and most importantly SAFE. This will likely be the last seat we ever need (youngest is 6, 56lbs) and while that is kind of sad I’m glad that we found this brand so long ago.
My youngest picked the color herself -vibrant bRead more about review stating Only car seat brand I’ll ever buylue-and it’s very comfortable. She can easily buckle herself and the belt remains in place and doesn’t bunch up-like our previous 5pt turned booster (also Diono).
My oldest also has this seat in purple/pink (9yo and 65, tall for her age but we still use the back for maximum safety). We have had her seat for over a year and it has held up very well for daily trips to school and multiple days of use per week.
This is the perfect booster combo.

Saved my kids lives

We were just in a very serious car accident & my kids both had these seats. VERY SAFE! We all walked away unharmed. My kids were so safe in these Diono seats. Just bought 2 more replacements.
