Confused about infant seats and what features really make a difference? Let us help you out!

The 6 key points to what you are looking for in an infant seat are:

1. Weight Capacity & 2. Height Capacity You want to make sure that your little one will be able to use this car seat for as long as possible. If your child is on the smaller side, you have nothing to worry about. But if your child is one of those at the top of the charts, be sure to check the weight capacity and height capacity on any infant seat before purchasing, so you don’t find yourself stuck a few months later.

3. NHTSA Rating

All car seats rated by NHTSA meet Federal Safety Standards & strict crash performance standards. While all rated seats are safe, they do differ in their ease of use. The NHTSA ratings will help you decide what car seat would be simplest for you to use.

4. Side Impact Protection

Almost all car seat manufacturers nowadays tout the extra Side Impact Protection they add to their infant seats as side impact protection becomes more important to parents and caregivers.

5. Dimensions

If you are the proud owner of a smaller, compact-sized vehicle, then your choices are going to be more limited when seeking a car seat. While car seats all remain in an average range of sizes, many seats won’t work for your vehicle. Be sure to check on the width specifically, as you need your infant seat base to be buckled in properly

6. Weight

Infant seats are usually taken in and out of the car pretty frequently. Most parents want the lightest seat they can get, while not compromising on safety and standards. Note that not necessarily are the heavier seats safer in any way, but there usually is some sort of connection.

A bonus features most infant seats boast of is an Infant Insert. This allows your newborn to fit properly into the infant seat for the first few months. After that, you can remove the insert for your growing baby.

  1. I got the older version of the mico, and let me tell you – I should have splurged on the Mico AP – the differences are pretty significant. The Primo Viaggio would have been my second choice, but that is much more

  2. How helpful! Wish I had this when I was buying my infant car seat. Do you have a chart like this for booster seats?

  3. Penelope what are the differences between the Mico and the Mico AP?
    I have been really impressed by what I’ve seen and heard about the Mico AP and I find the price in the reasonable range.

  4. Temima – the Mico AP has much more cushioning – it’s well worth it.

  5. I am due in June and have narrowed my infant car seat down to the Nuna Pipa and the Cybex Aton Q. I know that the Cybex is not out yet and I see that the Pipa has not been rated, but based on what you know can you give me some positive and negatives about the seats.

    Thank you

  6. Hi Heidi,

    The Nuna Pipa is an extremely safe seat with its load leg feature, and side impact protection. It is a very light weight seat weighing only 8.7 lbs and holds up to 28.5 It features an oversized canopy that drapes over the seat with mesh window. Whoever has this absolutely LOVES it! No complaints.

    The Cybex AtonQ is going to be real cool with many new added safety features including more side impact protection. In addition, the entire seat resizes when adjusting the harness which is the coolest option yet! It will also have a large extended canopy

  7. Which dimension in the comparison chart reflects the length, or distance from front to back? I drive a small 2 door car and need whatever takes up the least a amount of space Between the back seat and the back of the front seat!

  8. Are there mothers who have had more than one baby and tested or reviewed the Nuna Pipa, Maxi Cosi AP, Maxi Cosi Micro AP, and the Maxi Cosi 30? If so which one did you prefer best and why?

  9. Hi Nicole, none of the moms here have ever owned two infant seat yet and each are happy with their picks. A big contender in making their decisions is the stroller that they intended on buying.

  10. Hi! I’m registered for the uppababy 2017 Cruz and uppababy Mesa. The Mesa release date has been delayed and I’m looking for a backup just in case as I’m due in June. I see that the uppababy Cruz is compatible with Nuna pipa and maxi cosi. Buy buy baby said also peg perego with a special adapter. I just can’t seem to decide!! Seems like the maxi cosi does not hold has high a weight so won’t be able to use as long. Is this true? I’m leaning toward Nuna pipa but would like to hear more feedback about this car seat.

  11. We love the Pipa here and definitely recommend it instead of the Mesa! You can give us a call to learn more about this amazing infant seat.
