  • Easy to install, stylish, padded, roomy, fits front and rear car seats


  • Hard to tighten straps, fiddly system of buckling up harness, armrests don't adjust

The multi-group Cosatto Zoomi could see your child from 9 months until they don’t need a car seat anymore, making it an economical investment. And while it offers all a car seat should and easy installation, the fiddly harness lets it down.


Cosatto has 40 years of experience in designing practical and stylish items for babies and its new car seat collection covers all age ranges, from the Groova Group 0+ infant car seat, the Moova Group 1 car seat, and lastly the Zoomi, which I tested with my 16-month-old son Nathaniel.

The Cosatto Zoomi is a Group 1/2/3 car seat, which means it’s suitable from 9kg up to 36kg, or roughly 9 months to 12 years. The car seat fixes into your car with the main passenger seatbelt and has a 5-point safety harness for use until your child is 4 years old, then the main passenger seatbelt takes over.

As soon as I took the Cosatto Zoomi out of the box, my toddler Nathaniel was fascinated by the bright orange shade on the detailing (the Roundabout colourway) and was very happy to sit in it before it even went into the car! If orange isn’t your thing, the Zoomi also comes in a pink option, called Oopsi Ditsi.

At first glance, the Zoomi had everything that a car seat should - side impact protection, chest pads, safety harness, adjustable headrest, washable covers. But it was only when I compared it with the car seat Nathaniel was using before that I felt it was lacking, especially for its £85 price tag. The basic store’s own-brand Group 1/2/3 car seat Nathaniel was using previously is £30 less, has moveable arm rests and an audible safety alarm if the harness comes undone during a journey. These I definitely missed on the Zoomi.

What we love

I found the Cosatto Zoomi very easy to install. It took about 5 minutes and the instructions were very clear. It’s also secured with the rear passenger seatbelt, so you don't have to worry about whether your car has ISOFIX or not.

The Zoomi is very roomy, more so than Nathaniel’s used to and I noticed that he started to look out of the window more than he usually does.

Finally, I’m very impressed with the 4-year guarantee that comes with the Cosatto Zoomi.

What to watch out for

The 5-point harness is needed until your child’s 4 years old or 18kg, but it’s quite difficult to tighten the shoulder straps with the adjustable strap, though I think I just didn't have the knack.

The two shoulder straps meet and clip together in the middle before being fitted into the crotch strap. However, the fastening that holds the two straps together keeps coming undone at the slightest wrong touch when I try to put them into the crotch buckle. It’s a feature that I first thought would be brilliant - Nathaniel sometimes wriggles getting into his car seat and it’s quite hard holding two parts of a clip together to meet the main buckle - however, it turned out to be troublesome and annoying.

Who is the Cosatto Zoomi car seat best for?

Two-car families or those after a spare in a grandparent's car.


MadeForMums verdict

The Cosatto Zoomi is a fun-looking, smart seat with longevity. However, one of the practical additions could prove to be more troublesome than helpful.
