Diono monterey® XT Booster Seat

Fantastic investment. My daughter loves her booster, and is far more comfortable in it than her previous booster. Love that the shoulder width can be made bigger, my kids have broad shoulders. Easy to use, comfortable, vibrant colour, very good fit - the belt placement is really good. Very happy.


Perfect seat. Light and super easy to install or move between cars. So good I’m buying a second one for mums car.

I found this booster very easy to install and it will fit my very tall 8 year old granddaughter as a full booster for a while yet and then will be used as a half booster for her until her younger brother and cousin need it. She has however complained that it is not very comfortable as it catches her across the top of her shoulder blades where the adjustable headrest meets the back piece. There seems to be quite a hard ridge just there and perhaps it is that she is just at that height that there is a problem however I was a bit disappointed with that part. Overall it seems a good seat for the price.

Awesome car seat

Well this is a brilliant car seat that will see my daughter safe and secure until she doesn’t need one anymore. So easy to install with the latch/isofix option. It’s a little wide for my Nissan Juke so I have to fiddle a bit when doing up the seatbelt but it’s worth for the quality. Great service from Winkalotts to WLG as well.

Samantha Armstrong

We needed to get a bigger seat for our 6 year old she is a bigger girl with wide shoulders this seat fits her so well and she still has more room to grow. The seat was very easy to install.
I definitely recommend this seat!!
