I bought this to replace my son's convertible seat that he was getting too tall for. He's four and not ready to be in a straight booster yet. This seat has the 5 point harness to the go into a booster. The height adjustment is easy to adjust. It has decent padding and my son likes the cup holders. My husband had no problem installing it. We didn't recline it although there is the option to. Cons: it is a heavier seat. I don't switch vehicles often so not a big deal. It is narrow enough that my 3 kids can fit across my highlander in it. Another com is the release for the strap that you tighten the seat belt. It's hidden in the front. If you had tightened the seatbelts when your child wore just a shirt and then wanted to loosen them a little because of a coat, it's a little inconvenient compared to our previous seat. Overall, we're happy with it.

We loved our Britax boulevard, so when it was time to buy a new seat we wanted a britax. We are disappointed on the one handle tightening system. It takes a lot of work to get the seat feeling tight. Our previous seat was very easy to install with two straps to pull, one on each side. I am also very disappointed with how hard it is to tighten the restraint straps. We have had the seat for over a year and I kept hoping they would get softer, but no luck. I have to get inside my van to have enough strength to pull my son's straps tight enough to be safe. This seat still has features that I like such as the easy to remove cover and the quick easy adjustable strap, however I wouldn't recommend this seat.

      Installation

      By meemee

      from Killingworth, CT, United States

      Comments about Britax Pioneer Combination Harness-2-Booster Car Seat with UltimateComfort - Summit:

      Great looking booster seat. Very difficult time installing using the harness and the latches. It appears the harness is a little too short, making it difficult to attach it to the latches in the car. Have other Britax car seats, have put them in and out of cars without difficulty. This one was very difficult due to short harness. Otherwise, it is another great carseat from Britax.

      I would never spend money on anything but a Britax. I have a top of the line Graco as well but would never buy another. Britax is the way to go. Worth the money.

      Uncomfortable design

      By Grandpa 72

      from Los Angeles CA

      Comments about Britax Pioneer Combination Harness-2-Booster Car Seat with UltimateComfort - Summit:

      I recently bought the Britax Pioneer. In my humble opinion, the crotch belt buckle is very poorly designed. Even with the belt in the forward position, this is extremely difficult to fasten and pinches my grandson whenever I have to fasten him in. I would like the Britax male executives or engineers that designed this to try it on themselves and see if they would like a hard plastic and metal buckle tightly fastened next to their private parts and then drive over a bumpy road. Is this the best you can do?

      Works well

      By Dadskills

      from San Diego

      Verified Buyer

      Comments about Britax Pioneer Combination Harness-2-Booster Car Seat with UltimateComfort - Summit:

      This seat works well. It is easy to install and operate. The extra cup holder is a big plus as well. The reason I don't give it a five is the harness tightening strap is a little difficult to cinch down just right. It seems to be sticky. The Britax car seat we replaced was smooth as butter.

      This is by far the best carseat we have tried. When we upgraded to these and put the old ones in the spare car, the kids complained every time we used the old ones so we ended up getting a second set of these.
