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 it’s safer. It’s made very well and steady. The thing it doesn’t 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.

It’s 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 it’s 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.

Awesome Seat
This harness booster is awesome. It is totally not moving after being installed due to Britax’s 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 Gandma’s 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.

Once you have used a Britax you realize how other products are far inferior. This seat does not budge once you have it in place & I feel great about having my little one in it. Peace of mind is far worth the price tag!

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 :)

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.

Love this car seat!
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.
ProsVery sturdy Easy to install 2 cup holders Versatile with age Comfortable

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.

We love our new booster car seat. It's the great quality that comes with each Britax product. However, watch the date of manufacturing, ours was already a year old out of the box.

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.

Great product for the price
We've had great luck with other Britax carseats, so when our 4yo outgrew her Boulevard 70 CS, we looked for another Britax. I was a little turned off by the prices of the higher end booster seats, so we decided to try out the Pioneer. We installed using LATCH, since our daughter isn't 45 lbs. yet, and I was disappointed to see that the Pioneer doesn't have two separate straps (one on each side of the car seat) to tighten the seat into place. There's just one big strap that spans the back of the seat, making it harder to get a really secure fit. That's my only knock of this seat. Other than that, seems nice and sturdy, great safety features, and a cute pattern.

Great product
We love the quality and look of this seat no my complaints are it's so heavy, but once it's installed it doesn't matter and there are built in cup holders, on both sides, which makenit significantly wider. I'd recommend to havebinenon one side and maybe removable, to allow more room when it's needed (like 3 car seats in the back of a Ford Focus). Other than that, very happy with the purchase and quick shipment.

Great Booster but it could be better
High Quality, the metal frame certainly give the booster a solid feel. We purchased one Pinnacle ClickTight and one Pioneer, installation is certainly a bit harder than the more expensive models with ClickTight but certainly manageable. If you are going to move the booster a lot, spend the extra money if you can. We seem to be experiencing an issue with the pull strap as its not pulling evenly on each side, I will update the review once I figure out if its an issue with our specific seat or user error (certainly possible).

We love this big girl carseat/booster!
We bought this for our 4 year old daughter, she loves polka dots and purple and I love this brand, so it was an easy choice! We got this carseat for a great price compared to other online retailers and it shipped quickly! I was a little confused on the set up...I had a hard time figuring out the instructions for getting the tether straps out and how to place them under the backrest. It was easy to adjust the shoulder straps and get it installed in the car. When the carseat is empty, it rattles...bad enough I'm going to take it out and figure out what it is. My daughter loves it and seems very comfortable while riding. Her head still falls forward when she falls asleep, but I'm not sure if any booster can prevent that. So far after a few weeks of using this, we are overall happy with our purchase!!
ProsSturdy...seems padded nicely...cup holders hold sippy cups...colors are bold and pretty...easy to adjust's not real bulky
ConsA little on the heavy side, but not too rattles when my daughter isn't riding in it...hard to get the tether straps out of the base when first setting it up...doesn't recline much (most boosters don't anyway)

Happy with my purchase!
My daughter loves her new pink seat! The seat seems very good quality and is everything I expected out of a Britax seat. I was a little surprised that it was harder to get a tight installation with the seatbelt than my other Britax seat (Marathon)... but I did not want to shell out the extra money for the Clicktight version, considering I will not be installing this seat very often. I would definitely make the same purchase again. Albee Baby's shipping was super fast, and you cannot find better prices anywhere!

Love the Britax Booster
Looking to switch my 4year old to a booster seat but wasn't comfortable w him just in a booster w seat belt, love this car seat w the 5point harness!! He will be in for a long time. Albee baby was a great website with very good prices and great customer service, the only place to buy a car seat from!!!
ProsMy little one can climb in all by himself and get buckled up! Cup holders are a great reach so he can grab a sip whenever.
ConsIt's heavy but that could be a pro too w the steel back.

Excellent purchase!
My kid just turned 2 & loves his new seat. It fits great in our Tundra w/ the access cab, which is what we were looking for. Also, it was easy to assemble; my husband had it set up in the truck within 10 minutes. Great seat for the price!

great booster seat.
This is one of the best booster seats you can buy. The straps are generously long for a pretty large child. I bought another brand that is nice but those straps do not fit a child over 60 lbs even though it says it will. It is good quality, user friendly, my 5 yr old granddaughter can fasten and unfasten herself. She enjoys the cup holders and comfort too. The slight recline allows for napping without the head falling forward. Highly recommend it.

Britax pioneer
We love this car seat! We are sure that our 5 year old is safe with the 5 point harness and adjustable head support that grows with him. The quality of this seat and all britax seats is easily seen and felt. When he's ready, we can tuck the harness straps and use the seat as a booster. We have one in each vehicle, but this seat is also easily moved if another family members takes my son for a ride in their vehicle.
ProsMy son and buckle the 5 point harness on his own, easily adjustable head support, easily transports from vehicle to vehicle, easily transforms to booster seat, fairly slim and takes up much less room than a convertible seat.
ConsA little heavy at the base. I see this as a positive also as I know my son's seat is secured.
