Summer Infant Affirm 335 Car Seat Features

Safety 

The Affirm 335 rear-facing car seat was made to address safety concerns and make installing the car seat easier. Moreover, they created a new base for the car with incredible attention to the needs of both parents and babies.

The biggest new feature is the steel bar – called Steeloc – that helps to adjust the car seat in your car perfectly. 

Not only does the Steeloc arm make installing the car seat and base easier, but it provides reinforcements for safety. It provides steel encasing for the entire base as an added safety measure. Even in the event of an accident, the base will not crumble, but hold its structured design. 

The seat comes with SureShield protection, which is a fancy way to say it’s been tested for front, side, rear, and rollover impact. It’s been 2X impact force tested for assurance your baby will be protected in any type of collision. Also, the car seat conforms to ASTM 2050 hand-held infant carrier standards, and you can take it on airplanes.

The car seat offers full-surround EPS energy-absorbing foam with a deep and low seat to not just provide a comfortable place to sit, but also provide layers of protection. 

Finally, the car seat is only as safe as the installation of the seat. Watch the video below before installation to ensure a quality fit as the seat only works properly when installed correctly. Don’t worry, the installation is super easy.

Base

The car seat only works in the rear-facing mode, which you will see when you put it into the car. The uniquely designed base adds tons of safety features, as stated above. Installing the base takes only a minute or two to accomplish and provides more protection than other car seats. Furthermore, the base includes stickers and a level to ensure a proper fit in your seat, so you know your baby is as safe as possible in a car. 

Seat 

The seat has the important job of transporting your baby comfortably, and it does! It’s also comfortable for parents to carry because of the ingenious design. First, though, you need to know your baby can only use the seat until their head is about one inch below the top of the car seat. 

Next, the ingeniously designed handle – called FloatCarry – reduces strain on your arm and hand to allow you to carry the car seat with comfort and ease. As the seat weighs just under 8 pounds, it’s much lighter than other seats, giving a massive advantage to parents tired of carrying 15 pounds of baby and 15 pounds of car seat weight! 

Furthermore, the seat releases and installs back into the base or stroller easily with an audible click to know the seat is secure. Babies will love the seat too, with the deep and low angle allowing them to comfortably relax while on the road. The textured fabric inside provides a cozy, nest-like place for babies to feel safe and secure even when not in their parent’s arms.  

Lastly, the seat comes with an infant insert that removes easily for added comfort for newborns. Even the harness comes with padding to keep baby’s tiny little neck from getting pinched by the nylon straps. When you take the insert out, your baby will still get a cozy nest to sleep in for car rides or stroller trips. 

Harness

The harness offers five points of contact to keep your baby in place. It’s adjustable to create a perfect fit. Make sure you watch the video below for the safest way to buckle up a baby into a car seat. As stated above, the harness has padding on the shoulder to keep babies comfortable. 

Moreover, the harness has four height positions for the shoulder straps, in order to grow with the baby for a correct fit. Always make sure the harness fits over the baby’s shoulders and not underneath. Adjusting the seat straps is easy to accomplish via the front strap, which allows for a secure fit for babies to stay in the seat safely.

Canopy

The canopy offers thick protection from the sun and rain. You can adjust the canopy to provide shade as needed or leave it pushed back for no protection. However, the canopy does not offer a pop-out sun visor or a peek-a-boo window, which seems to be the only downfall with this car seat, along with most other car seats. 

Height & Weight

Your baby needs to meet the following height and weight requirements to use this car seat:

  • Baby must weigh 3 to 35 pounds (1.4 kg to 15.8 kg)
  • Baby must measure 15 to 32 inches (38 to 81 cm).

As the seat works for babies who weigh just three pounds, it’s a perfect option for people with a premature baby ready to go home. See more great preemie car seats

Installation

The Affirm 335  was designed to transfer your baby from the car to the stroller to your arms in no time at all. You can install the seat using the LATCH system, the vehicle seat belt, or in Rideshare Mode without the base for when you are not using your own vehicle.

Installation couldn’t be easier, as Summer Infant made the system so easy to get right. You will fall in love with the car seat and base every time you compare it to older car seats. 

Take a look at the video to see just how easy the installation of the seat is for even newbie parents.

A quick note: notice the handle becomes a part of the safety measures by becoming an anti-rebound bar. It rests against the seat in a down position to protect your baby even more. 

Travel Systems Featuring the Affirm

Summer Infant created the Affirm 335 Car Seat to go along with the Myria Stroller Travel System. You can also buy the car seat and turn it into the travel system of your choice with the Summer 3Dpac CS, and the Summer 3Dpac CS Lite for more options.
