  • Headrest height and shoulder protector height and width can be precisely adjusted with 20 different position settings, simple attachment to the Isofix points in vehicle for improved side-impact protection, extra cushioning, strap guide opens at the touch of a button and locks automatically, ergonomic shaped shell seat


  • Some toddlers may master the unclipping of the belt

The Transformer X-Bag car seat is super-safe, innovative and adaptable as your child grows from age three to twelve. An easy button-operated system allows the the seat to be adjusted to the precise height of your child – both the height of the headrest and the height and width of the shoulder protectors can be simultaneously adjusted in 20 progressive stages.


The seat offers complete side impact protection with its compact enclosed shell design, while the ergonomically designed seat shell ensures a comfy ride for travelling toddlers and beyond.

Available in black with grey or beige, my four-year-old daughter Florence gave the black and red version a whirl, which looks most racy and dynamic. The design is fully ergonomic and is labelled an ‘enclosed shell design’, which offers brilliant support from top to bottom as well as complete side impact protection with three cushioned layers.

What I loved

It’s easy for my daughter Florence to climb in herself and the comfort factor is high, which means my toddler sleeps pretty well in it without too much head bobbing forward action. Far better than a basic booster, the entire seat adjusted to fit Florence precisely and can be lengthened as she grows. To do this, it uses what’s called a ‘button-operated Variosize system’ which ‘adjusts both the height of the headrest and the height and width of the shoulder protectors within 20 progressive stages’. It’s so easy to use and it’s appears really sturdy, so I’ve high hopes that it will last until Florence’s early teens. Not sure how clean it will be by then though!

What to watch out for

Even though my 4-year-old is boosted fairly high in her seat, she can actually reach to undo the belt and she mastered this trick a bit too quickly. Fortunately, at this age, it is easy to negotiate and discuss the dangers of unclipping the belt when in motion, and once Florence was over the novelty factor of her new in-car independence, it was no longer a temptation. Also, according to some of the other mums who have purchased this seat, once the seat has been set to the required position, it locks tight and can only be adjusted by taking the seat out of the car and lying it on a flat surface. Not to be mistaken for broken.

Who is this car seat best for?

It has such universal appeal, I can’t think of any child aged 3 or 4 and up to 12ish that wouldn’t benefit from using it. Unless of course, your daughter is still in her ‘pink’ stage!

MadeForMums verdict


Easy to install, extra inbuilt safety with Isofix anchors, high on comfort, and a fantastic cost per use investment.
