    • Well made and worth the higher price

sturdy and easy to install

    • High quality
Love that these have the latch attachment and are designed to install three across. They are heavy duty and high quality like all diono seats so they did not disappoint. I needed my husband's help to install the arms since the click in mechanism is really difficult, but he had no trouble with it. Luckily you only have to do thay once. The cup holders can be installed or stored under the booster, which is a brilliant design. This is my third diono purchase with my six kids and the product holds up extremely well. Can't go wrong. ... show more

    • Nice quality
Nice quality and durable booster seats. My grandkids have mentioned these are very comfortable. They are a bit heavier than other booster seats I have had in the past. I think these will be the last that I purchase.

We bought these for my boys to use on our 9hr beach trip. It provided more room in the car, easy to install, has multiple securing devices to make sure they stay in place and are comfortable padding for riding. There are 3 latches that keep them in place including one for the top of the headrest. They’re sturdy and made it through the 9hr car ride plus some. Will be purchasing more for my husbands car ... show more

    • Amazing
Easy to install - and my kid loves sitting in them. Very lightweight and great for travel. The red clip was a little confusing to put on the shoulder seat belt strap at first, but I figured it out.

    • Booster seat
Color: Pink Cotton Candy Size: Pack of 2
These were purchased for a child that was close to hitting the weight range of their carseat but was a little too short to not have a booster. The 120 lb weight limit made these the perfect choice.

These boosters save my life !! I have two sons and a daughter due in June . And I was so nervous I wouldn’t have a booster to fit with the Evenflo infant car seat . I found these and ordered them and they fit perfectly with each kid having a cup holder as well ! I had different boosters at first that did not work at all but these ones especially because it gives you space to buckle are way easier ! Also we have ordered buckle extensions just to see if that could also help with an even easier buckling! I have a Toyota Camry and thankfully I don’t need to buy a new car just yet ! ... show more
