Sturdy, comfortable, long term gig
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.

10/10
I give it 5 stars because some booster do not stay in place and my kid does not beg to get out as soon as she’s seated. So far we are loving it. It does promote a better posture, kid is safe and in place and seems to be very comfortable. My toddler is 25 lbs and 33 inches tall and fits perfectly, but still have more room and more straps space to adjust as she grows. Booster is not too light or to heavy but it stays in place safely and it’s very sturdy. It’s super easy to clean just wipe it down and you’re done.

Highly recommend
Highly recommend for a safe, sturdy, easily cleanable seat for a toddler. Boosts my tiny girl enough that she can reach the table for meal time.

Great choice
This thing gets the crap beat out of it and it still looks brand new. Easy to clean. Doesn’t stay tight though.

Great table booster seat
Very happy with this booster seat for our 2 year old! She loves sitting at the table like a big girl. It fits out chairs perfectly and can be adjusted if needed. Worth the money!

Pricey, but it works
This really does make my four year old sit up well! We just got this and have been using the booster part of his high chair for a while before this. We liked his high chair piece because it kept him sitting up nicely, but recently he's started slouching a lot in it, so we figured it was time to switch it up. I didn't love the price of this one, but it is working to keep him sitting up tall. He says it is uncomfortable when he tries to put his legs to the side, which is kind of the point- to encourage them to stay forward. With some effort, I was able to pull the straps out that would buckle him in. He doesn't need them, and I do wish they came out easier. Even if we did use them, I'd want to take them out to wash periodically. It seems like it can be used without the white part, so the height is a little adjustable, which is good. We're happy with it so far. I think a $45 price point would be more appropriate.

Seat arrived damaged/used
Extremely dissapointed. For how expensive this booster seat is it DEFINITELY arrived used/damaged. Instructions already rubbed off and weird scuffs, marks on the seat.

Solid, sturdy and easy to attach to chair - toddler loves it.
This booster seat feels solid and does not move once attached to the chair - attachment is easy. Feels safe for a child to be in and brings them right to table at a level that allows a feeling of participation from a child. Our user is 2 years old and transitioned easily - always chooses this seat over the high chair.

Amazing booster seat for kids with poor core muscles
My daughter has spina bifida and has weak core muscles so is prone to slouching when sitting. This seat keep her back in an upright position which means she can sit with us as a family at the dinner table. So worth it its brilliant!

Facile à installer et à nettoyer!
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!

Great posture, two levels of seating
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.

Superb Quality
Excellent adaptability, this will be used for years. Attached safety straps are long enough to fit our larger dining chairs. Very happy!

Great seat, great service
Great seat! Purchased a long time ago for my first child before they had the extension platform, I recently contacted and they sent the platform quickly by mail for free as my second child is now using. It is a bit tricky with rounded back chairs - but I got a dollar store seat cushion to rid the space behind my child’s back in our chairs. Very happy overall, and found it very easy to use for my tall child for a long time (did not outgrow fast).
