## Customer Reviews

### ⭐⭐⭐⭐⭐ Facile à installer et à nettoyer!
*by  on Reviewed in Canada 23 May 2026*

Très bon siège rehausseur ergonomique! Il est stable, sécuritaire et bien conçu pour que bébé soit confortablement installé à table. J’aime vraiment le support ergonomique qui aide à garder une bonne posture pendant les repas. Facile à installer sur différentes chaises et simple à nettoyer après les repas (ce qui est un gros plus 😅). Mon enfant y est bien et on peut enfin manger en famille plus facilement. Je recommande!

### ⭐⭐⭐⭐⭐ Sturdy, comfortable, long term gig
*by  on Reviewed in the United States 28 February 2026*

I have one for both of my kids and really like them. They're overall easy to keep clean, really easy to travel with if needed, and it's a comfortable design. It's held up super well so far with no damage. It's been great from age 1 to age 3 for me, and presumably beyond that.It allows we some mobility (they can twist around in it) but if set up properly it feels safe and secure.

### ⭐⭐⭐⭐⭐ Great posture, two levels of seating
*by  on Reviewed in Canada 8 January 2026*

Big fan of this booster seat. My toddler transitioned to it easily out of her high chair. It reinforces great posture and autonomy. It's easy to clean and has two levels depending on the height needed. It's also easy to throw in the car when we're going to visit friends or family. Great quality and a long term investment.
