It's been about a week and I have to say we really love the Diono Monterey Booster!
We couldn't try out these booster seats for our twin 5 year old boys in stores so we had to rely on reviews, which all seemed to be great.
This was our criteria - safety, comfort, ease of use, longevity and price.
The boys had spent the last few years in Britax Marathon, we loved these seats for the safety, comfort and easy instal. I imagined going Britax again but .....wasn't ready to move away from the latch system. We did try out the Graco Turbo Booster- my son found it to be uncomfortable. Then he sat in the Britax Frontier, he said it was comfortable, but the price threw me, I simply could not afford it. The Britax Parkway was deemed comfortable by the kids but doesn't have Latch anchors and one of my boys isn't yet 40 pounds.

The Diono Monterey fit the bill for us, it's very soft and padded, the back and side head protection is not obtrusive. We love that it uses the... Read more

First, let me say that I have 2 Sunshine Kids Monterey boosters - one from 2009 & one from 2010. Had no problems w/ either of these - they are awesome products! Unfortunately, I cannot say the same for the Dion 2012 model.

I recently ordered the 2012 model and experienced nothing but problems w/ the quality. First one arrived w/ numerous quality issues from the factory, as did the second. That in itself was a huge surprise/disappointment, but I also question the modified design of upper seat belt guide. Has anyone else experienced this?

Since I ended up returning both seats due to quality issues, I only had the opportunity to briefly install the new model.

My daughter and I are thrilled with her new Monterey Booster seat. She says that its very comfortable and she loves the color. I am very pleased with how easy it is to move the booster from car to car. I am thrilled that this booster has the LATCH system. The instructions for instalation were clear and easy to understand. The adjustable width and the adjustable head rest is wonderful. I was worried that going to a booster would make it difficult for her to sleep on long car rides but there is plenty of head support for her to rest on. The low profile makes it very easy for my daughter to get in and out of this booster. We also appreciate the two cup holders in the base. They are at the perfect height for her to reach and use. Thank you!!
