Rated 5 out of 5 by from We bought this booster seat and liked it We bought this booster seat for when my nephew was with us and he loved it and it worked great for us, while we had him with us. It was easy to use and he seemed comfortable in it. I also feel like this product is well made and Durable I love that it’s neutral so I can use it for may baby if it’s not expired by the time they can use it and if so I will just buy another one. I’m happy with this brand and will be buying more of the difference stages of car seats for when my baby is born since I’m pregnant right now. This brand is a good brand to use for babies. I look forward to buying more stuff for my baby. I feel this brand is very reasonably. And I would highly recommend this to family and friends.

Rated 5 out of 5 by from Great car seat, love the cupholders I purchased this booster seat for my daughter because it has cupholders built in! That’s one of my favorite features because it gives her a convenient place to stash her cup and, or snack. This seat is comfortable for her & the padding is easy to slip off & clean for me. This is one of my favorite booster seats & I’ll definitely be looking into getting one when my younger son is in one of these booster seats!

Rated 5 out of 5 by from Love this booster seat This booster seat has been amazing to myself and my family. We figured a booster would be much easier when we would have to travel with our family or friends. Much easier to take out and transport if we need to. This seat feels comfy and sturdy. My daughter loves sitting in it. I'm thinking because it has awesome cup holders for her. It's easy to set up and super light to carry around too. We are very happy with this seat and definitely recommend

Rated 4 out of 5 by from Love the simple design! I received this booster seat for my review from Evenflo. I love the stylish design and how easy it is to put the cover on and easy to remove for cleaning. The cup holders are a great addition. I have always trusted Evenflo seats for my son as we had a triumph seat for him. We were in a car accident and my son was unharmed, mostly because of how great the car seat is! The paramedic even commented how it was a great seat from his experience seeing car crashes involving little ones and he confirmed my initial thought of what a GREAT SEAT! So great that I bought the exact same seat to replace it after said accident. I’m thrilled Evenflo has seats for every stage my little guy is in!

Rated 4 out of 5 by from This sporty model has two cup holders (very important for my son!). It also is easy to assemble and install in the vehicle. It is machine washable and so easy to wipe. My son is not complaining about any seat discomfort and he loves the colors! Note the arm rests are not adjustable to better fit for the child and the cup holders can be issue when you put bottles. (Doesn’t leave room for the arms)

Rated 4 out of 5 by from Easy to put together, unsure about some use The booster was easy to assemble according to the manual. However, the manual did not mention about the flap of the cover that goes over the seatbelt positioning strap. There was no hole for the strap to go through, so the seat cover would lay flat. In the manual, the loop of the seatbelt positioning strap was pictured to be on top of the plastic it was wrapped around. It doesn't say if it is safe to fasten the flap down over the seatbelt positioning strap; I was worried that making the strap go around the secured flap would cause slack and make the use of the seat unsafe in that manner, so it was left undone to allow the seatbelt strap to be tight enough. This is the biggest question of design, as the manual does not say how the strap should be positioned at the anchor point while in use, so I chose to be cautious, only using it as shown. Other than that one flaw, it works well so far. Comfortable for the child and easily positions the child to wear the seatbelt safely.
