The road ahead on your parenting journey is constantly changing. Think of your little one who’s not so little anymore. And perhaps you’ve added another addition to the family, too. The luxury of strapping one baby into an infant seat has now turned into a circus act of getting everyone settled into the car. 

With the RodiFix booster car seat, we’ve made your everyday adventures a little easier. The booster seat has a seat belt guide, so big kids from 40-120 pounds can easily buckle themselves right into the seat. The beauty of being independent gives them confidence while it offers you a little more time to load everything into the trunk.

With every car seat we design we keep you and your child in mind. That’s why the rigid LATCH connectors make the RodiFix simple and easy for you to secure and install. With its Front-Access Recline System, the Rodifix fits better in your backseat and offers a different level of comfort for your growing child. And for added safety, it features Air Protect® for superior side impact protection around your child’s head, where it’s needed most in a side impact collision.

The RodiFix belt-positioning booster also features a multi-height headrest and expanding side wings that grow along with your child and help ensure that the vehicle belts are in the best position.

Supreme Comfort with PureCosi™

We’re committed to caring for precious life, ensuring that only the highest quality materials are used in our products. With PureCosi™ we’ve launched new fashions that no longer require fire-retardant chemicals. Carrying the future means protecting your little one, and our planet.

Soft-to-touch cushions and premium fabrics and padding are designed to provide supreme comfort for your child. Premium washer-and-dryer-safe fabrics keep kids comfortable and hold up wash after spill – after wash after spill.

White headrest on new model????
August 12, 2022
We purchased an older model in grey, and love it! It was the only seat that fit in our small back seat that didn't block access to the belt fastener. I really appreciate the no armrest design!! It's about time to purchase another one for my younger son, but this year's model only comes in one color, black (good) with a white/light headrest. I cannot buy this, it will get so dirty so quickly! Why white???? Please bring back the grey or another neutral color!

Great booster!
April 27, 2022
This is the best booster we've ever had! It was so easy to install, my 6-year-old son commented that "it's called Cosi because it's so cozy" and he has no trouble buckling up on his own.

Great t.
Nice seat especially for tight areas
December 11, 2021
This is a great all around seat with side impact protection and a clean narrow fit with easy access to the buckle. The only drawback is the absence of a top tether. This is important for 3rd row installation where there isn't a lower latch option.

Super comfy !

My daughter loves this seat ! She says that it super comfy and she can easily do the seat belt on her own. I love that it’s flame retardant free and very slim. The only con is that there are no arm rests or cup holders .

This booster is perfect for 3 across in my back seat. I have it in the center position, and the lack of armrests means I am not worried about improper belt positioning! Love it. Amazing, fast Albee shipping, as always.

Very Comfortable and Great for Limited Space
June 10, 2021
I got this because we needed a more narrow seat for my husband's Q5. My daughter really likes it and it doesn't go into the other seats. There is no cup holder, but that really didn't have an impact for us since she can still place a water bottle right next to herself.

Excellent booster. Easy in and out.
April 21, 2021
Albee Baby had the best price and the order was shipped within a day after ordering. Very happy with the company and the product. The booster is very easy to resize for depending on which kid is where. I have a 3, 5 and 7 year old and it can easily be adjusted to safely fit all three, with the touch of a button.

Maxi-Cosi is amazing!
January 22, 2021
I have used Maxi-Cosi from the start. From infant carseat, to convertible carseat, and now the belt positioning seat. What I love most is how soft and cushioned the fabric is. I could never understand how other car seat brands are so hard and stiff. Also they make it super easy to remove and wash the fabric! The only downside to this is no cup holder. But that is not a deal breaker for me, although it may be for some. I love the narrow base.

Comfort at its best
January 2, 2021
We had the maxi cosi car seat for our kiddo and he finally outgrew it and decided to stick to maxi cosi since he had comfort specially for long trips. The booster seat did not disappoint, my kiddo loves it.
  • Pretty light compare to similar boosters seats
Best Uses
  • All time use but definitely for long trips when the kiddo falls a sleep
  • It does not bring a cup holder need to purchase separate and did not realize. Accessories much needed.

Nice seat
November 18, 2020
My grandson likes this seat. He says it’s comfortable. The one complaint I have with it is the seat belt guide. The belt gets twisted in it, making it almost impossible for him to use by himself. I’ve had to buckle the belt every time he’s used the seat. If I could return the seat for something better I would, but I’m not willing to pay return shipping on something I couldn’t look at prior to purchasing.

This is amazing my son is 6 and on the tall and thick side. This is so amazing it’s built better then other boosters and clips great no hassle on the seat or on the person who has to put it in. Leans back witch is great When he falls asleep. The seat belt loops clips in to its own place. I even sat on it. Will be buying another one for the other car for sure.
  • This has side that will wide and fit the child and it goes back also and easy to install.

Easy and Safe!
July 4, 2020
This was a breeze to install and we could not be happier. In our vehicle, the seatbelt buckle is very difficult to reach (sits low in seat) so the fact that this does not have armrests is a wonderful feature for us! Our child can easily buckle his seatbelt as soon as he pops into the car. He has told us how much more comfortable this is in comparison to his other car seats. This has been a wonderful transition from convertible to booster. Thank you, Maxi Cosi!!

Nice seat
July 2, 2020
This seems like it will be a nice seat for a while. We like the color it blends with the interior of our car nicely. Also the latch system is great, it keeps the seat from falling over and just seems over all more secure and safe compared to the many that do not have this system. We would recommend to others and plan to purchase another when our next son is ready for this stage of a seat.
  • Soft fabric, cushy, adjustable head rest, has a slight recline, latch system
  • Wish it had the anchor system as well

Awesome Booster Car Seat
October 21, 2019
I thought the booster car seat was great. I do childcare and both the parents and I love it. They feel that their 6 1/2 year old daughter is safer and so do I. It was a very easy install, and removal - the parents borrowed it from me for a weekend trip and loved it! They had their own by the time they arrived home!! I love the comfortable sleep our little girl gets ❤️

I appreciate the extra head support, especially with transitioning from the convertible seat. It makes me feel better knowing there are extras supports. The ease of installing the seat is a big draw to us as well as we sometimes have to move it between cars. Overall, satisfied with our purchase!

Perfect on-the-go booster!
September 19, 2019
This booster has been perfect for us to use in our car, friends cars, our nanny's car, and grandparents cars! It is so easy to install, which makes it a breeze to put in and take out of cars. I love having such a safe, secure booster for my kiddo to travel in, and have never once been disappointed with Maxi Cosi products because of this. I want my son to be safely restrained, even has he is getting older and transitioning out of a convertible carseat and into a booster - the small booster seats aren't enough to satisfy my safety concerns - but this one is perfection!

excellent carseat
September 7, 2019
my daughter loves the seat, she likes all of the upgrades to the seat, mostly the fact the seat can slightly recline with the seat of the car. I like the fact that it doesn't have cup holder, it makes it smaller and fits the seat better. most cars have cup holders so it doesn't seem to be an issue at all, one less place to collect old gold fish. I feel the seat is safer because its now secured with anchor attachments, overall great!

No more booster sit tipping!
September 6, 2019
The best thing about this seat is that I no longer have to watch my big kid struggle to buckle as his entire seat pivots when he leans over. Because of the latch it stays in place when buckling, and around corners. It also provides a lot more comfort than the other boosters. We are getting another one for our other car!

We love the RodiFix Booster Car Seat
September 4, 2019
When It was time to transition our daughter to a booster seat, I was apprehensive about moving away from a 5 point restraint. However, We found this seat very safe and secure. A fan of the high back for lumbar support. We also loved how easily we could transfer between vehicles and it was narrow enough to fit safely between two other car seats, when needed. My daughter finds the seat comfortable for our long commutes. We would highly recommend this seat to anyone ready to transition away from a traditional car seat.

Easy to install and safe to ride
September 4, 2019
I have moved my 2 kids into the Rodifix and they love it. It's great they can independently put their seat belt on and I know they are safe. The adjustable tall harness allows us to use this seat for a long time. This booster seat is not bulky and allows room for someone to sit comfortably in the middle seat.
I do wish it had a cup holder because we are always on the go.

My kids love this car seat! Our previous car seat really hurt their back and was uncomfortable when they would sleep. Not only does the RodiFix seat have extra cushioning but it has extra head support so their head doesn't move around when they fall asleep. Thank you!!

Riding safely and comfortably
September 3, 2019
Not only do my kids love this Booster seat, but I feel very secure that they are riding safe!! I like the easy install feature to clip in my seats so the seat stays in place. I also like how my kids can independently buckle themselves in since the seat has a slit for the seat belt so it stays in place and is not on their neck. The head adjustment will be great as they grow with the seat.

Solid, Comfy Seat!
September 2, 2019
My 5-year-old granddaughter is using this seat and loves it. She nestles right in and says it is super-comfortable. It feels sturdy and has all of the features one would expect from a high-quality child's booster seat. The only downside is that we don't have cup holders in the back seat, and this booster seat doesn't have any built-in.

Easy installation and SUPER easy to use by my 6 year old!

We just moved our son from a 5 point harness to this maxi-cosi booster seat. It was incredibly easy to install -- it clicks into the latch system. My son has been using it now for a week and he can easily buckle and unbuckle himself. The seat itself is attractive, not too bulky and very well built! I can see us using this for years to come, and then for our second child as well. We have it currently installed in our Odyssey and it's working very well for us!

This booster is great! I recently purchased this product to transition my daughter out of her convertible car seat. Our family has always loved maxi-cosi, and this booster did not disappoint. I love that the fabric is easily machine washable and extremely comfortable. I washed and dried the cover and did not have any difficulties putting it back on. Installation is easy and the booster itself is slender. I love this product and will purchase another when my youngest gets older!

Fantastic Booster Seat!
August 28, 2019
We use four other booster seats between our cars and the grandparents' cars, and the RodiFix is my favorite! This is an awesome booster! The rigid LATCH system is incredibly easy to install in an Odyssey and an Accord. We have two children (5 and 8) who ride in highback booster seats, and one child (10) who rides without a booster between the younger children. I love the design of the seat bottom of the Rodifix. The seatbelt buckle is much easier for the child to reach while sitting in the Rodifix as compared to other boosters... this makes a big difference if there is another child or adult riding next to the booster! Some boosters are so wide that they almost cover the buckle, which can cause frustration with buckling right next to another passenger. The easy recline feature is a great bonus... it makes the booster fit perfectly against the seat of the car. My 5 and 8 year olds both prefer the Rodifix to the other seats. I want to buy a second one!!

I like that this can be used for a long time with our kids. They are on the lower range of the weight limit so we'll be able to use for years. Not too bulky, which is great when you have more than one child. Also like that they can be used with the shoulder strap. Very satisfied.

We love the Rodifit. Our very tall 4yo was getting super cramped in her convertible car-seat and is now happy to jump into the Rodifit (and loves being able to buckle herself)! It seems really comfy for her but the footprint isn't huge in our car and it's really easy to install.

August 27, 2019
We are very happy with the RodiFix booster seat! After switching over to the Maxi Cosi Mico Max with our second baby, we went with the RodiFix for our first when transitioning to a booster. The biggest plus is that it is light weight and easy to use for us and our daughter. It hooks into the car easily with the latch system and she is able to buckle herself in without it getting caught up in the seat. The incline option is great because it helps it fit easily in both the Tahoe and truck. The upholstery on the seat is upscale and pairs nicely with my black leather seats... it helps to hide the mess that my backseat has become!
