In a Hurry? Here’s Our Top Picks…


What to Look for in Car Seats for Twins

The Weight Requirements

Since many twins tend to weigh less than the average weight when they are first born, make sure that the baby car seat can accommodate their lower weight. There are many car seats that will hold infants as small as 4 pounds, which can be especially important for parents with twins.

Convertible vs Infant Car Seat

The convenience of a carrier that locks into a base is great for carrying your infants around, but as they grow out of infancy and into their toddler years, infant carrier car seats won’t work.

A convertible twin car seat, on the other hand, will hold infants, toddlers and, children, usually with a weight max of 100+ pounds. Convertible car seats tend to come with a higher price tag, but it’s a great, one-time investment. The downside is, you won’t get the convenience of carriers.

The Size of Your Car

For parents driving vans and SUVs, the size of the car seat won’t be that big of a deal since larger vehicles can easily accommodate two car seats. However, if you do have an older child or have a smaller vehicle, you need to consider the size of both the car seats.

Measure the back of your car seat, not only width-wise but also the depth, from the back of the seat to the front seats. This will help you when selecting a car seat.


Always check to make sure that the car seat is comfortable for your two little ones! Are there any bumps or tags that could irritate their skin? Is the car seat the right size for your twins’ ages? Is the material comfortable against their skin?


As we mentioned before, a convertible car seat tends to be a little more, but it’s also a one-time investment since it will grow with your child. But we understand double the car seats means double the price and we made sure to include more affordable options for parents on a tighter budget.

A Word on the Infant Car Seat Test

When babies are born prematurely (earlier than 37 weeks) or have certain medical conditions, hospitals will require them to undergo an infant car seat test. Parents must provide the car seat they intend to take the child home in, which the baby will then be required to sit in the car seat for a determined amount of time, usually 90-120 minutes, and a nurse will monitor the baby’s oxygen level, breathing, and heart rate.

If your baby, or in the case of twins one or both babies, does not pass the car seat test because they cannot tolerate the semi-reclined position of a traditional infant rear-facing car seat, your doctor may require you to get a car bed. However, the doctor may also wait and repeat the car seat test in order to make sure one or both babies are medically stable.

Staying within a budget can be tough when you’re buying for two. That’s why we made sure to include this Safety 1st OnBoard 35. And just because it is more affordable than other car seats doesn’t mean it lacks in quality.

The OnBoard 35 is lightweight but very durable, providing the side impact protection your babies need. It has 4 harness heights in order to adjust to your ever-growing child. For the extra small tots, there is a support newborn insert for the infant seat to provide extra protection.

The carrier is compatible with QuickClick strollers. The covers are machine washable as well for easy cleaning. The base isn’t as easy to install as the other infant car seats on this list, but once installed, it was easy to remove and click-in the carrier.

  • Grows with child 5-110 pounds

Frequently Asked Questions

Q: How do I install a car seat?

A:  First, refer to the manufacturer’s instructions. They will provide step-by-step instructions on how to install the car seat. If you are having problems or are unsure if you have installed the car seat correctly, visit the National Highway Traffic Safety Administration website to find a local station that can help.

Q:   How long do I need to keep my babies rear-facing in a car seat?

A: If you think rear-facing car seats are for babies, think again. The National Highway Traffic Safety Administration recommends that parents keep children in a rear-facing car seat until they can no longer fit in their seats which for most children is at about 4 years old.

Placing a car seat rear-facing has been proven to keep kids safest in the event of an accident. No matter what car seat you choose, be sure to read the manufacturer’s instructions to find out the weight and height limit of the car seat.

Q: My child spilled food/drink on the car seat. How do I clean it?

A:  First, check the manufacturer’s instructions to find out the best way to clean the car seat. All car seats can be vacuumed regularly to get crumbs that may fall into the nooks and crannies of the seat. You may also need to remove the car seat itself to see if any food or drink has gotten on the seat of your car.

In general, most car seats have a removable cover that can be hand washed in the event of a spill. Never soak the car seat cover though. Hand wash with a mild detergent and hang to dry.

Unless noted by the manufacturer, we strongly suggest you do not put the cover in the washing machine as it may wear out the cover prematurely.

Bottom Line

If you are on the hunt for a car seat or rather two car seats for your twins, then we highly recommend the Graco SnugRide Click Connect 30. It is our top pick because we love that it’s not only safe and comfortable but comes at a fair price.

Two SnugRide Click Connect 30s will fit comfortably in most vehicles, but as we mentioned before, for parents with sedan and compact cars, be sure to measure your back seat first. As an added bonus, it’s also compatible with Graco’s Click Connect Strollers, so moving out of the car and onto a stroller takes only a couple of clicks.

We hope you enjoyed our article covering the best car seats for twins!
