The Monterey XT is a full-featured, expandable high-back booster seat designed to fit growing children 40 lb to 120 lb. The adjustable head rest and deep, aluminum reinforced sides are lined with energy absorbing EPS foam for side impact protection. The shaped and contoured seat ensures the correct seating position and makes for a comfortable ride.

My 5 year old (43in/45lbs) enjoys riding in this seat and was pleased to finally move to a booster. Seat is easy to install and adjust. I was happy to see that they added UAS. The only thing keeping me from giving 5 stars is the material. It doesn't seem to be as wear resistant as our Rainer seats (2014 model) but only time will tell. Overall a great seat.

Easy install! The arm rests appear to be a bit longer than the previous Monterey version. The cup holders also have a snack holder. The only down side for me was that the fabric is much more loose than the previous Monterey seat. It isn't as attached to the seat as I would like. It sometimes bunches at the bottom and back area. But not a reason to not buy it. I still recommend this seat!!

This is a replacement for us from an accident, we had previously owned the same seat. Love this seat. We do a fair bit of highway travel and because this one clips in to UAS, I feel like this is a safer and more secure option in the vehicle. My son has a small booster in our other vehicle and he much prefers the security and side head pieces on this seat.

We have 2 other booster seats and this one, by far, is the best design and most study of them all. As a result for a long car rides we only use this seat because it feels like it offers the best protection. Many booster seats don't click into the car, this ones does giving it solid feeling.
