(1 customer review)

A comprehensive booster seat with modern styling. The MXT features metal reinforced expandable sides and energy absorbing foam for superior protection.


Diono lead the way with safety and innovation producing only high back boosters which offer side impact protection. Although the European Safety Regulations don’t require this, Diono believe side impact protection significantly improves the safety of children when travelling in the car and as such ensure all their boosters have deep dual wall side impact protection.
The range of Diono highback boosters have been engineered with added strength and important safety elements to give parents peace of mind and the Diono mXT is no exception!

A comprehensive booster seat with modern styling. The MXT features metal reinforced expandable sides and energy absorbing foam for superior protection. There is a 12 position head rest and longer seat bottom to properly fit children as they grow. MXT is easy to connect into the car utlising an integrated Y strap so the booster doesn’t move when not in use. Retractable cup holders and snack trays keep bits and bobs tidy!

  1. Laura

    By far the best Booster seat we have tried! We have been through a few booster seats now and this one is such amazing quality. Very well padded and protected with reinforced metal sides for extra safety and protection. This seat can also be stored flat which can be very handy if using it on an ad hoc basis or need to store it away.

    The seat comes with simple instructions and is very easy to install. At first I was a little worried how I would fit this in the back of my car (I have 3 children in car seats) But despite looking bigger than some other car seats it really didn’t take up much room, and we were able to fit all 3 seats in perfectly even when we expanded this seat – We have a ford mondeo for those wanting an idea of size and another booster seat and a large stage 1 seat.

    I had great fun playing with the expandable sides and head rest, it really is so easy, just a smooth turn of the dial at the back of seat and an adjustment of the safety strap and its done, and fits a chunky 10 year old with plenty of room to spare so more than suitable for the new car seat guidelines.

    For the purpose of the review I took the fabrics off the seat – Very easy to do, also extremely easy and not at all fiddly to put back on. I even washed the fabric at 40 degrees and there was no colour loss or colour run, also you can see how well made this seat is under the fabric.

    There are 2 deep snack trays either side of the seat that fit a drinks bottle and cup nicely with an extra compartment for snacks. They are nice and deep too so no worries of said snacks spilling out easily. The snack trays tuck nicely under the seat when not in use also.

    We loved the colour we had (We had the green one) Its not like any other colour we have seen used for a car seat, very unique and stylish and actually the stock photo doesn’t do it justice.

    Overall I would – and have recommended this to parents, very user friendly, comfortable and safe. Such a great price for an exceptional product
