Great Product. Great Experience.
Product came as advertised and on time. Love this booster.
ProsVery safe booster. Easy to use. Easy to install. Love the recline feature. Lots of cushion on the seat and back.
ConsHeavy. Which is understandable considering all the safety features. This is not a complaint, just something to be prepared for. Also be aware it is wider than non-five-point-harness boosters. Again, not a complaint.

Great harness car seat for tall child
My daughter is almost seven, we did not move her to front facing until her fifth birthday. I want to keep her in a 5 point harness for as long as possible. She is 50 inches tall which is the general height limit for a lot of 5 point harness car seats. This seat allows her another 7 inches before she switches to seat belt. I really like it so far, it was easy to install and she says it is comfortable. I love the two cup holders and she seems to have more leg room than her last car seat which was more reclined putting her knees at an angle. The only con I have had is it does tend to make a chirpy squeaking noise when it is empty I assume it is from the foam rubbing the plastic without weight holding it down. Already planning to buy my Mom one so we don't have to shuffle this one. Well worth the money.
ProsTaller 5 point harness use Two cup holders Easy to install Comfortable
ConsSqueaky chirp noise when empty
Best UsesTaller child who still needs 5 point harness

Great Seat
I bought this seat for my then 3yr old to move him forward facing because he was passing down his convertible to baby brother. He instantly loved the seat. It has an easy install, and very easy to use otherwise as well. We have now had the seat for a year, and it is still in the shape it was in when I bought it new. I would definitely recommend this seat to anyone that has a kiddo that is at least 2yrs old and forward facing.

Excellent harness to booster!
I bought this seat based on reviews and price point. It was to replace the convertible seat that our daughter was outgrowing. I researched just as I did when buying her earlier safety seats. It arrived quickly and was ready to go right out of the box. I read through the installation instructions and got it set up in my van. It went in pretty easily and tightened up really well. I dis have to adjust my brain for the V style tether but otherwise installation was quick and easy. My daughter was excited to try her new seat and said it is comfortable. She is able to do her own buckles after a little lesson and seems to enjoy the ride. The safety of this seat seems legit as it is heavy and has steel reinforcement. The amount of padding is less than our previous seat but I haven't heard any complaints. We are using it in harness mode.
ProsEasy installation, Feels safe, great safety ratings, stylish, comfortable, nicely sized for van or car use.
Best UsesUsing this for 4 year old. Hope this will be her last seat needed.

Tricky belt path
I find the belt path a bit troublesome. For the one I used the LATCH with I had to completely remove the strap attachment to get the LATCH cover part of the seat to sit flat again. I also think the belt path is an issue because it doesn't really sit back in the seat so that the carseat cover doesn't stick out. I (an old CPST) was able to make it work, but I'm afraid a person who knows less about carseats may struggle with this. The belt path needs to recess back into the seat a bit so that cover easily covers it. Overall it is a BRITAX and that is what I'll pay for. I have had many of their seats and I'm always happy with their products. This seat was to replace a Diono Radian rxt.

LOVE this seat
We have three of them now. Two cup holders, easy to install and to set the child into. Evidently comfortable and our 5 year old can unbuckle himself. I regret ever having bought any other kind of seat. Love this style.
ProsTwo cup holders and easy go to install and adjust.
Best UsesOur almost 2 year old is too big for the convertible styles - and they slant backward when facing forward. With this Britax, he sits upright when facing forward and enjoys being able to see out the window and communicate with us. This is a great seat

Safe, easy to install, comfortable
This car seat already has a great review for me after reviewing its safety ratings. But after receiving it, the installation was simple, it was medium weight not super light but also not so heavy that myself (as a smaller female) couldn't lift it above my body to place in the car. My son really loves it, it's comfortable and when he fell asleep it kept his head upright!!

Best Car Seat
This car seat is the best. My daughter is a tall 4 year old and she fits it perfectly. We went through 3 difference seats before we was happy. Worth the money for your loved one!
ProsFits tight in vehicles, works for the bigger taller kids, the piece between her legs is not right up on private.
Best UsesAll stages!

Easy to use and easy to clean
This is a great booster seat for our next step past the regular car seat. I wanted to be sure it had good safety ratings and strong harness system. My kiddo is heavy but thin and muscular so we needed something that would tighten well and keep me confident in his safety. This car seat tightens well without being uncomfortable for him. If he spills it is pretty resistant from stains. We clean up fast with detergent and water or a baby wipe and it's been a-ok. It was easy to install. And is very simple to adjust height. I am very happy with this choice in seat. It feels very comparable to our Click-Tight Frontier at a much better price. I am very happy with this choice.
ProsEasy to install Cleans well Nice color choices Simple size adjustments
ConsCup holders could be slightly larger

Great product and super fast shipping
The car seat was exactly what I was looking for. It is very heavy, but I love that it is heavy because I feel like it means its safer. Its made very well and steady. The thing it doesnt have that I wish it did is the clips that attaches it to the seat, you have to attach it with the seatbelt. The shipping time was so fast, I received it with in a couple of days.

Its a good car seat but can be better!
I got 3 of these boosters seats. I like that is a five point harness booster seat which gives me peca of mind that my kids will be safe in it. My kids like it and love the arm rest and they said is comfortable. The only think that I don't like is how hard is to adjust the straps. They supposilly move with the head rest but its so hard! I read that with the Frontier (a better version of this) is easier to adjust the straps so my advice is that if you have the money get the frontier instead of this as it feels more sturdy.

Solid and tight fitting seat
We bought this seat for our grandchildren. It was fairly easy to install and it's easy to secure the harness. Great seat so far. Expect it to last many years since it can be used as a booster seat too.

Would not recommend
I bought this car seat for my three year old four months ago. I researched and decided to go with this one over the diono I normally buy. Huge mistake! I despise this car seat. There have been many days that I wanted to sit this car seat out by the trash. It feels cheap, it does not tighten easily, and it a very awkward seat in the back of my van. My three year old often complains of how uncomfortable it is too. I would definitely not recommend this seat

Very hard to tighten!
I am upset with the performance of this car seat. We had a Britax convertible car seat first and LOVED it (still do for my younger child) but this car seat is so hard to tighten that I get upset/frustrated every single time I have to put my daughter in it. I plan to buy another seat instead.

Awesome Seat
This harness booster is awesome. It is totally not moving after being installed due to Britaxs great design. I have a rather tall four year old and he is so comfortable now!!! The only problems (which are really not important) is that the seat squeaks when child is not in it and the color is nothing like the picture. My husband chose the reflect color to match his tan and black interior. When we received the seat it is not any shade of brown but an odd silver shiney color. This seat and this brand are the only brand I will use to keep my little safe and recommend to other parents.

Britax Pioneer for Gandmas Car
So many ways to secure this seat to my backseat to ensure a safe ride for my precious granddaughter. And it passed the approval of her parents with flying colors!
ProsThe seat becomes a booster seat when the child reaches a certain height and weight.
ConsMy particular car seat was purchased in February 2018, but it was manufactured in January 2017. I had already lost over one year of usefulness by the time the seat was delivered. Car seats have expiration dates based on the manufactured date. My daughter in law is a stickler for only using seats that are not expired. I had already gotten rid of another seat that had expired. This one is its replacement.

Just what we were looking for!
This fits my 4-year old daughter perfectly. She loves the cupholders and we no longer have to dig for the bottom buckle. We were happy with our convertible before this, but if you have the $, it makes sense to move to this to take your child through the rest of their carseat life :)

Does not install to safety standards in Toyota Sienna
I purchased two Pioneer seats for my kids; these were my 3rd and 4th Britax car seats respectively. I read reviews (not from this site, but from other parenting review sites) prior to purchasing this model that said this model is comparable to the Frontier as long as you don't mind taking extra time to ensure proper installation. Given the price difference between the Pioneer and the Frontier, I decided to try this model. With any car seat, I meticulously read the manual so I can ensure proper seat adjustment and installation in our cars. I did the same here. Given my kids' weight, I chose to forego the LATCH installation and instead use the lap shoulder belt. No matter how tight I pulled the belt, no matter how much I pushed the car seat down with my own weight, I could not get the Pioneer to tighten enough to move less than the recommended 1". In fact, the seat was moving more like 6-8" in either direction after attempting to tighten. Thinking it must be user error, I looked up install videos and even called Britax directly. Ultimately, the only advice the service agent was able to give me was to find a local certified car seat technician who *might* be able to help me. If this was the kind of hassle I would have to go through every time I needed to remove/reinstall the Pioneer, no thank you. After almost an hour trying to install this seat - and still not being able to do so safely - I returned both Pioneer models. Not worth the headache or the lack of peace of mind that my seats were not installed safely. I have since purchased the Frontier with ClickTight model (2 of them) and while significantly more expensive, the Frontier installed safely in my van in a matter of minutes.

Very Hard To Install
I love Britax and have the Frontier booster. I wanted this for an extra seat. It is really hard to install. I have been installing carseats for my kids for over 6 years and I am very particular about doing it correctly. This seat has a plastic cover over the unused latched that makes it very difficult to route the seat belt correctly. It is very frustrating and I returned it and will just pay extra for the Frontier click tight.

Too complicated
This seat is very non-intuitive to the point of frustration. I wanted to throw it away. Your engineers made something way too complex. You don't explain things well enough in the instructions either. Very poor performance from your company. How do you get the bottom connectors through the seat. Not explained at all.

Before this one, I had a greico. It was so hard to get out of the car that I had to literally cut it out. I returned it and a friend recommended the Britax brand from this site. Best purchase ever! It is so easy to put in any vehicle I am driving. I can literally put it in less than 5 min. My daughter loves it, it has 2 cup holders, and I feel extremely safe with her in it.

Best Decision I made for my 5 year old!
We got the pioneer because it had so many features of adjustability and let me tell you what it is amazing! My son loves it and feels super secure in it. He is 4'0" tall and weighs in at 50 pounds and I don't have a single issue with this carseat. We even have it completely latched down in our car along with using the seat belt on the seat belt path. This was the best decision EVER!!!!

Great Booster
My 5 year old still met the weight and height requirements on her convertible carseat but she was hoping to get a big girl seat! This satisfied her and I as I knew she was still safest in a 5 point harness and she was able to get in and out much easier!

Easy to install
Bigger and heavier than i thought but installed easy. Seems well made and she says she is comfortable. I definitly prefer this over my Dionos, but Diono is rearfacing until 50 lbs. This purchase makes for car seat #7. The only car seat I like better is my Britax Advocate with the click feature, makes it easy for grandparents to know when its tight enough.
ProsEasily installed Secure, i feel she is safe
ConsHeavy Bulky, dont think i can fit 3 across.

Britax Pioneer G1.1 Harness-2-Booster Car Seat - Silver Cloud
I am very satisfied with the quality of Britax and how easily it can be adjusted to child and vehicle. The Armrest are great for adjusting and moving as well as resting your arms and protection. The snack and/or cup holder does not any of the standard child water bottles such as Contigo or Camelbak.
ProsEasy Set up in and out of the vehicle. Easy to clean Good Air flow around the Childs body Built in snack and/or cup holders.
ConsCup holder is 1/2 inch to small for standard size child's water bottle
Best UsesIt is used daily.

great seat
The Pioneer has the same top harness slot height as the Frontier, just without the clicktight and huggs pads.The install isnt as easy as the click tight, but no more difficult than most forward facing car seat installs.The color is fantastic!
ProsHigh harness height (still fits my 9 year old). Comfortable. Easy to adjust.
ConsNot as easy to install as the click tight. But worth it for the budget savings.

Love Britax and Albee's prices
Exactly what we were looking for. We have a 6 year old and all her car seats have been Britax- the only brand that has steel for back support. Only the safest and best for my babies!!! Albee prices are great for quality products such as Britax and shipping was pretty fast! Would definitely continue shopping with Albee.
