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.

Great for positioning. Needed for adults
As an occupational therapist, I love to support any ergonomic positioning products! Daughter was breech with hip dysplasia, so improving her position in any way was a must for us. This seat is great now that she has more independence during meals. Easy to take off when guests are around as well as clip on when she eats. Worth the cost and is very sturdy/durable. Easy to wipe down

Would recommend for squirming toddler
The upseat has been great for my almost two year old. She started refusing her high chair and wanting to sit in a regular chair for meals. We looked into different options and decided on the upseat, and we are pleased with that decision. It easily straps to the dining chair and feels secure. Itโs easy to just quickly wipe down after meals, and the buckles are simple, even when securing a squirming toddler. She doesnโt seem to mind sitting in it, so I have to assume itโs fairly comfortable, and the straps are adjustable so it should fit her for a while. Overall, would recommend!

great first chair at a table from using highchair
Easy to set up, adjust, and clean. Very sturdy and easy to move from chair to chair or travel with. Straps are study but the buckles to strap the kids in adjust too easily while they are sitting in the chair.

Best brand for kids seats
We had the small original Upseat for our son when he was a baby (currently using it with our 5 month old) and it was great, so we decided to try the booster seat when it came time for our two year old to move on from his highchair. He loves it and seems very comfortable at the table using this. It seems safe and secure and we haven't had any issues so far. Easy to clean and great quality as expected from this brand. The design is sleek and seems very durable.

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.

Great for posture
We love the booster seat. We take it everywhere and it fits most every chair. Very sturdy and comfortable. Itโs light weight and has buckles to keep our children from falling out. It was out of the box ready to use, less then 5 minutes to set up and use.

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!
