Obviously the most important feature parents will want to consider in a car seat is safety. Luckily, both the KeyFit 30 and the Primo Viaggio 4/35 rank very high, so there is no particularly wrong choice here. They both employ a secure, five-point harness with one-pull tightening. Both have an energy absorbing EPS lined shell. They also both include removable new-born head and body supports for optimal safety and comfort at all ages. There is little doubt that your baby will be well-protected in either system.

Your child’s comfort is, naturally, a huge factor to consider as well. Both these car seats are roomy and comfortable, with adjustable straps. Both use comfortable, easy to clean materials. If there is one complaint users have shared about either seat’s materials, it is that there are a few leather parts on the Primo Viaggio 4/35 that may get hot in warmer climates.

When it comes to canopy coverage, this is where the KeyFit 30 beats out the Primo Viaggio 4/35. The KeyFit 30 canopy is removable, easily adjustable, and provides more coverage for greater baby protection and comfort in the sun. When it comes to parent comfort, the KeyFit 30 comes out ahead here as well. On the Primo Viaggio 4/35, the space between the canopy and the handle is very narrow, making it difficult to hold and carry when the canopy is up. In contrast, the KeyFit 30 has much more space for your hand between the canopy and handle, making it easy to carry.

Most Comfortable for Child and Parent: KeyFit 30

Ease of Install

Installing a car seat for the first time is usually a frustrating hassle for parents. However, both Primo Viaggio 4/35 and the KeyFit 30 seats are fairly easy to install, especially compared to many other seats on the market.

The Style

While style is in the eye of the beholder and hardly the most important feature of a car seat, it is worth mentioning that these are both exceptionally stylish car seats. While the Primo Viaggio 4/35 is more compact, it is not significantly so, and both seats can fit easily in compact cars. If there was one thing that edged it over the other, the KeyFit 30 offers a larger variety of colors and styles (such as polka dots), letting parents choose how best to match their car and preference. Users have also mentioned superior quality in the KeyFit 30 canopy material.

Primo Viaggio 4/35

Peg Perego Primo Viaggio 4/35

The Primo Viaggo 4/35 is a sleek, safe, and trusted system. Its dual stage cushion system can support an infant as small as 4 pounds, which can be removed so that this seat can be used until your baby is 35 pounds. The side impact protection is adjustable to six different positions with no re-threading required.

The included base of the car seat is easy to install, and has a stable, secure latch system. The seat and handlebar have color coded belt paths as well, to help belt routing when you are not using the base. The handle is short and compact which, as mentioned above, can make carrying the car seat with the canopy extended much more difficult. However, the design of this car seat also causes the handle to act as a natural anti-rebound bar, which can limit rotation in an accident, so that’s definitely a plus.

The Primo Viaggo 4/35 attaches easily to any Peg Perego stroller without adapters. That this seat is made by Peg Perego is a large draw towards this car seat for many people, as Peg Perego is a well-established Italian company with a great worldwide reputation. However, this is what likely contributes to the higher price, since part of what you are paying for is the name brand.


  • Higher height and weight limits
  • No rethread harness
  • Slightly more compact
  • Integrated anti-rebound bar


  • High in price
  • Short handle

One thing I didn’t realize before having kids of my own, though, is how much stuff babies need—and how complicated it can all get! With so many different options out there for things like car seats, strollers, and cribs, figuring out which ones are right for your family can feel confusing and anxiety-inducing, especially alongside all the other work you have to do to prepare your home for the new arrival.
