Between the Safety 1st Grow And Go And Maxi Cosi Pria 70, I will choose the Grow and Go mainly because of practical reasons that it can be the only car seat my child would need before finally being able to use the vehicle seatbelt. However, the attributes of Pria 70 are also worth considering so keep reading below and find out which of the two would fit in your ideals and requirements for a car seat.

Ideal Use


Safety 1st Grow And Go

Maxi Cosi Pria 70

Rear-Facing Weight:

5 to 40 pounds

9 to 40 pounds

Rear-Facing Height Limit:

19 to 40 inches

Up to 40 inches

Forward-Facing Weight:

22 to 65 pounds

22 to 70 pounds

Forward-Facing Height Limit:

29 to 49 inches

Up to 52 inches

High Back Booster Weight:

40 to 100 pounds


High Back Booster Height:

43 to 52 inches



Rear-facing maximum height and weight limit, and forward-facing minimum weight limit are the common traits of Maxi Cosi Pria 70 and Safety 1st Grow and Go.



  • Rear-Facing. Grow and Go outshines the Pria 70 in this area because we can use it for babies starting at birth to 5 pounds weight. Although reviewers mentioned that the 5 pounds minimum limit could not be realistic since the newborn harness system of the Grow and Go might only provide a snug and secure fit for babies starting at 7 pounds. This is still lower than the 9 pounds limit of Pria 70 that makes it useful only when the child is at least one month old.
  • Forward-Facing to Booster Mode. The Maxi Cosi Pria 70 has a higher forward-facing capacity than Grow and Go. Yet, even if the child is beyond the forward facing limit of Grow and Go, he/she could still continue to use the child restraint because it has belt positioning booster capability. While we can use the Pria 70 until the child is about 8 years old, we can use the Grow and Go until the age of 10 (based on this growth chart).

The Maxi Cosi child restraint would probably be a good choice if you already have an infant carrier or car seat and are looking for your child’s next car seat. The Safety 1st child restraint is an enticing first car seat to buy for your child since we can use it from birth until it can train your child for using the vehicle seatbelt.

Will It Fit In My Car?

These seats are both bulky and wide. They will not be a good option if you want a space saving child restraint car seat inside a small car or if you need to install 3 car seats in a row.



  • Fit In Cars

Most car seats are ideally placed in the middle of the backseat so as not to affect the legroom of the driver and the front passenger, especially when fully reclined in the rear-facing position. Such was the situation experienced by a parent reviewer of the Safety 1st Grow and Go, who said that this child restraint fits well in the middle back of their 2018 Toyota RAV4. If they place the car seat in either side back seat, they would need to move the front seat forward.

Another parent said that Safety 1st was tight fitting in their Jeep Patriot when installed rear-facing. One mother claimed that she also had to move the front seat closer to the dashboard for the car seat to be installed rear-facing in their Kia Soul. The same happened with another reviewer who has a 2011 Toyota Corolla. The back seat of a 4-door Chevy Silverado is a little smaller than that of a full crew cab Silverado, but a mother said that this car seat still fits fine even if completely reclined. There was also no problem fitting the Grow and Go in an older model of Nissan Sentra.

There are various factors that affect how a child passenger seat fits in a vehicle, such as its recline angle and the slope of the vehicle seat. For instance, if the Pria 70 is installed at an upright position inside an Acura MDX, the front passenger could still have enough legroom to use. Installed fully reclined, however, the knees of the front passenger will already reach the dashboard.

With its size, it’s no wonder that Pria 70 has occupied one and a half seat space inside a Toyota Avalon.  Other parents noted that they could install this child restraint in a 2017 Honda CRV and a Toyota Rav4 with no problem.

Recline Position


Lower Anchor Weight Limit:

40 pounds


Looking at the installation details of these two car seats from the table above, it is easy to see that they seem to be similar in many ways. Both allow the use of pool noodle or tightly rolled towel in order to achieve the required recline and level. Both have 3 recline positions and the same lower anchor weight limit. Both also have no lock-off feature for a vehicle seat belt installation so a locking clip is necessary. 

They both have a molded level line that will serve as a guide in determining if the car seat is at the correct level.



  • Recline. 

The recline handle of the Grow and Go seat is located at the front, so making adjustments while in the rear-facing might be challenging. Sloped seats such as in a Chrysler Town & Country will require recline angle #3.

The recline adjuster of Pria 70 is at the back of the seat. This makes it convenient to adjust the recline in the rear-facing. 

The same principle applies to both for recline. The higher the number of recline positions means, the more reclined the seat will be. 

  • LATCH. 

Pria 70 has push button lower anchor connectors while Grow and Go has j-hook style connector, which is probably why the former has a high rating from parents who approve its LATCH installation. For Grow and Go, many reviewers complained about its LATCH system being hard to use.

Safety 1st Grow And Go Maxi Cosi Pria 70
Country Of Origin: USA
Steel Frame: No
Five-Point Harness? Yes
Side Impact Tested: Yes
Approved For Airplane Use: Yes
Easy To Buckle And Unbuckle? Yes No


Maxi Cosi and Safety 1st are like sibling brands under their parent company, Dorel Juvenile. They make both car seats in the US. They both have no steel frames, but they are both equipped with a side impact protection, a 5-point harness system, and approval for aircraft use.



  • Side Impact Protection. 

Pria 70 has a unique side impact protection called Air Protect. While Grow and Go has padding and foam in its headrest for side impact protection, Pria 70 has headrest that contains pockets filled with air. When an accident occurs and the child’s head hits the headrest, it dissipates the air inside the pocket along with the crash energy. This efficiently reduces the chances of injury that could otherwise be fatal to the child passenger.


  • Real Life Accident Testimonials.

While at a stop sign, a car going at 30 to 45 mph had hit a car which gave serious whiplash and shoulder bruises to a mom. Her 18-month-old daughter remained sleeping soundly in her Grow and Go car seat.

Another 45 mph crash incident left a car totaled, but the toddler passenger did not suffer even from a small bruise. A family had a highway accident and most of the adult passengers were beaten up and bruised. Seeing that the baby passenger had no scratch at all, one of the injured passengers, who was then pregnant decided to buy the same Grow and Go car seat for her upcoming baby.

A mother highly recommends Pria 70 to new parents because she has experienced how effective it was in keeping her own baby safe.  The accident they were involved in wrecked their car and she suffered whiplash and bruises. Minutes after the accident, her 9-month-old baby girl was still smiling without even a scratch on her. She approved of Pria 70’s construction and padding.

The Seat


Safety 1st Grow And Go Maxi Cosi Pria 70
Is The Material Breathable? Yes
Seat Weight: 15.4 pounds 23 pounds
Machine Washable Cover? Yes
Roomy? Yes
No-Rethread Harness? Yes (excluding newborn harness) Yes

Easy To Remove Cover? Yes
Expiration 10 years 6 to 8 years
Comes With A Cup Holder? Yes, 2 Yes, 1
Shoulder Harness Has Pads? Yes
# Of Crotch Strap Positions: 3


Pria 70 has a self-wicking fabric that helps keep babies cool even during hot days. Based on the reviews, even if Grow and Go has no self-wicking cover, it was still also breathable.  Other similarities these two car seats share are easy-to-remove machine-washable covers, room for growth, shoulder pads, infant body supports, and the number of crotch strap positions.



  • Harness.  

Safety 1st Grow and Go has a better harness system than Maxi Cosi Pria 70, although both are no-rethread.

Grow and go has a harness system that can be adjusted according to the child’s height anywhere from 10 to 16.5 inches. Since they designed it to accommodate a newborn baby, they also equip it with newborn harness routing separate from the no-rethread system for older babies. Since it also has a belt positioning booster mode, the booster guide position of this car seat is at 18.5 inches.

Pria 70 has 9 available headrest positions from 10 to 17.5 inches. 

  • Encountered Issues By Parents.

One complaint regarding Grow and Go is that it tips over when pushed to get it securely installed. In one conversation among parent reviewers, one father shared a useful insight regarding this issue. He mentioned about the comment he read from the official installation video of Grow and Go where it was said that the latch strap has to be pulled through the belt path instead of from the side to get it snugly fit. He followed this instruction, and he was able to securely install his child’s car seat.

When parents first receive a newly purchased a brand new car seat, it is to be expected that they might find some strange issues with the product which is why it is necessary to always read the manual even though you have already installed other car seats before. One thing to expect is that some parts might be rather stiff or hard since the car seat is new. With Pria 70, many have noted that the buckle was stiff, but it got better after a considerable time of usage. 

Another reported concern of parents was the difficulty in tightening or loosening the harness straps. Yet, a little online search has led them to many resources that showed how the problem can be solved. Thus, those parents who initially expressed dislike and disappointment over Pria 70 have retracted their low ratings and corrected their reviews.
