Monterey® 4DXT Latch 2-in-1 Booster Car Seat

Description

The original 2-in-1 booster seat with one of a kind, easy-adjust, separate height and width expansion. Transforms from a high-back booster to a backless booster as your big kid grows. With 15 SafePlus® and style upgrades from the Monterey® 2XT.

We’ve taken the award-winning Monterey and painstakingly engineered 15 upgrades to create the next generation of boosters. From the remodeled headrest, enhanced fabric covering, contoured seat base and breathable exo-shell panels, we’ve considered every last detail to create a contemporary new look. Contoured to fit and shaped in harmony with your child, Monterey 4DXT adjusts and expands as your little one grows to offer wonderful all-round protection. The height and width can be adjusted independently for safety that envelopes their head and shoulders up to 12 years of age. A simple-to-use dial on the back adjusts the width of the seat to fit a child’s shoulders up to 20” wide, while the headrest adjusts up to 6.4” height with one hand for an easy precise fit. The remodeled headrest is lined with thick EPP foam for better child comfort and improved side impact performance.

This is combined with deeper side wings and Diono 4-layer Side Impact Protection System built in. From the EPP foam coating, to the molded rigid shell casing and EPS coated outer shell, we’ve lovingly engineered every detail to keep your little one safe, mile after mile. Here at Diono we don’t just stop at superior safety. The ergonomically contoured seat base improves the child seating position with luxury AIRTEK foam cushioning for total child comfort. We’ve even added breathable exo-shell side panels to enhance airflow to keep them cool on the move. We've reduced the width of the vehicle seatback to make installation easier, improving access to vehicle seatbelts and promoting independent buckling. And with easily removable backrest and intuitive belt guides, the Monterey 4DXT offers 2 seats in 1 when they are ready to graduate to a backless booster. Like all Diono boosters, expect up to 8 years of reliable service. So, when it comes to your next booster, look to the Monterey 4DXT latch to take your child on their journey in safety and style.

FAQ

Monterey® 4DXT Booster, Instruction Manual, Cup Holder

Diono booster seats can be used for children weighing 40-120 lbs. (18-54 kg) and are 38-63 in. (96.5-160 cm) tall. Typically once a child reaches 5 years of age they are mature enough to ride in a booster seat.

Diono high back boosters with a detachable back are the Monterey® 4DXT, Monterey® 2XT, Cambria® 2. All come with a detachable back to convert into a backless booster seat.

Our booster seats fit 2 across in most cars. Each vehicle model is different and allows for various seating positions. Consumers should consult vehicle owners manual for appropriate car seat placement in their car that may fit more than 2 across.

Solana® comes with fabric cup holders in the cover. Solana® 2, Cambria® 2, Monterey® XT, Monterey® 2XT, and Monterey® 4DXT come with two retractable cup holders. The Monterey® 5iST FixSafe™ includes a Radian® cupholder with easy snap in installation.

The Monterey® 4DXT is recommended to be installed with the lower anchors if you vehicle is equipped with them. However, it can be used without.

Diono booster seats are not meant to be used on airplane. Boosters require a lap/shoulder belt and airplanes only have a lap belt.

All Diono booster seats have a life span of 8 years, starting from the date you purchase your seat. In the event the date of purchase cannot be determined then we use the date of manufacture.

Please consult the seat manual. Diono Cambria and Monterey seats manufactured prior to 2017 can be used with Ford's inflatable seat belts. Newer models will not allow them to be used and will be stated in the car seat's manual.

Gus the goose Buster's new bff
My pitbull terrier loves his goose and has not tore this up but he had not tried either. He's funny with soft toys but loves A good tug of war or actual chew toy.

Fun Goose Dog Toy
I have a small dog with about 20 plush toys to play with. Added to her inventory now is the ILC Buy Interactive Goose Toy for Small Breeds. It took me a while to figure out where the toy "squeaks", and it makes the noise when the white banded neck around the goose is squeezed. My dog took an immediate liking to the toy and loves to carry it around the house, shaking her head back and forth with the goose in her mouth. It appears to be made primarily of burlap (see pictures) and is about 12-13" in length. Fortunately, my dog doesn't destroy toys, as some (probably larger) dogs do, so it appears to be pretty sturdy and well-made. After a week of playing with it regularly, the toy still looks brand new. I like the coloring and the size of the goose, and this is a nice addition to my dog's playtime routine. It is also priced appropriately for a dog toy of its size and quality. Recommended. Made in China.

Durable toy with a single squeaker
This goose seems to be made of fairly durable fabric. It's not flimsy. I had a hard time finding the squeaker in it at first, but then I realized the squeaker is located in the white neck! My medium border collie grabbed it first. Then my pitbull figured out where the squeaker was and ran around squeaking it for a while, which is her favorite thing to do. So this toy did get some interest from the pitbull especially. She isn't one to chew things up but really enjoys toys that make noise. Since the squeaker is in the skinny neck portion, it made it easy for her to grab hold of it and squeak it over and over again. I am giving this 4 stars only because in the whole long body of this toy, the neck has the only squeaker. I think it would have been better and more stimulating for my dogs if it had multiple squeakers or even some crinkles in the rest of the body...at least some crinkles in the flat feet of the duck. The sole attraction is that one squeaker in the neck. So it could be better, but I do like that it isn't super plush and full of stuffing that would be torn up in 5 minutes like most toys. My pitbull actually took this to another room away from her three sisters, so that means she really wanted to play with this by herself. That's a good sign.

Duck-time is play-time! Exactly what a dog toy should be!
Duck hunting for your living-room princess-pal best buddy goodest puppy in the world! Every dog deserves a chance to be a heroic duck hunting hero! This dog toy is a favorite of my pup. Duck-time is play time! This duck is made with several fabulous textures. There's a ropey texture around the neck, a burlap type texture for the body and head, and a felt-like texture for the bill and feet. My dog immediately tore the feet off! He always removes any hanging bits from all toys, so that's not a comment to the detriment of this product. He's working on the wings, now. My dog likes to chase this toy when I throw it or play tug-of-war with it, or is willing to sit and chomp on it by himself for a while. The rope is intact, still! This is exactly what a dog toy should be! Give your little buddy a hunting trophy!
