Super straightforward to use. As with many of these the manual could use some more detailed pics about seatbelt placement for a first-time booster seat user.

I am happy with my order. It arrived early and my kids are now comfy when travelling. They love the water bottle holder attatched to it. Installation is easy and it fits in our car perfectly.

Comfortable and easy to install. Cupholders slide in/out to accommodate seat width (Although can't use them on a narrow seat. Clips aren't seat-belt type, but more like the carabiner style. Easy to adjust.

It’s great! I really like all the features. Mainly for the two cup holders, light weight, safety latches to the car. I already recommended it to all my friends with kids.

I chose Diono as I know they are great quality - the only problem with these is that there is absolutely NO padding for the kids to sit on. I had to put additional padding in myself, just so they wouldn’t feel the plastic if the seat!

Great backless booster. Comfortable. Fold away cup holders were a nice surprise. Same excellent quality I’ve come to expect from Diono. Love the UAS connectors to keep the seat in place. Note it is wider than some of the less expensive alternatives.

My kid didn't want to use one anymore but changed her mind when I bought this one. It's really comfortable as it's bigger than the average, and the cup holders are very useful.

This booster seat is huge. Way bigger than your standard seat. I ended up returning because I felt it took up too much space in the back yard, as I sometimes need to fit 3 children in the back seat.

Great seat, but didn’t fit in my husband’s back seats (BMW 4 series Gran Coupe). The seat is too wide and covers the seat belt buckle. The seat fits perfectly in my car though.

Great booster seat but just a bit wide in a smaller car. Love that it has anchors in the back of the booster so that the booster can be anchored to the seat. Cup holders are a bonus!
