Best Car Seats for Twins

Car Seat Guide is independent and reader-supported. When you buy through links on this page we may earn a commission from Amazon or eBay at no extra cost to you. We don't accept payment for placement, and we don't publish made-up prices, specs or ratings — tiers ($ to $$$) show relative cost only. This is general information, not a substitute for your car seat and vehicle manuals. Have your installation checked by a certified Child Passenger Safety Technician (CPST).

Parents of twins need two car seats that fit side by side, install well and are manageable to carry. The best choices depend on your vehicle, your stroller plans and your budget.

We cover infant seats, narrow convertibles and fitting tips. See three-across guide.

Infant seats vs convertibles from birth

Infant seats are portable and click into strollers, which is handy with two babies. Convertibles save money long-term but aren't portable. Many twin families start with infant seats and move to convertibles. See infant seat vs convertible from birth.

Twin-friendly car seats

Width matters

Narrow seats leave room for another passenger or make it easier to fit two seats in small cars.

Weight matters

Carrying two infant seats is heavy. Lightweight carriers help. See lightweight infant seats.

Stroller compatibility

Double strollers that accept two infant seats simplify outings. Check compatibility.

Positioning in the car

Follow your vehicle manual for approved seating positions. Many families place seats on the outboard positions. A CPST can help.

Budget

Two seats double the cost. Consider value-oriented seats that meet safety standards.

Seat models, limits and features change. Always confirm current weight and height limits, fit in your vehicle and compatibility on the manufacturer's site before buying.

Planning your twin car seat setup

Start with your vehicle. Measure the rear seat width, note which positions have lower anchors and tether anchors, and check your vehicle manual for approved car seat positions. Many vehicles have lower anchors only in the two outboard positions, which works well for twins. Next, think about your routine: will you use a double stroller that accepts two infant carriers, or will you mostly wear babies and use the car seats only in the car? Finally, consider who else drives. Grandparents or caregivers may need extra bases or a second set of seats.

Before buying, test-fit seats if possible. Many retailers allow you to try display models in your car. Two infant seats side by side leave room for an adult in the middle in many vehicles; two large convertibles may not. A CPST can help you plan positions and check installations.

Carrying two infant seats

Two infant seats with babies inside are heavy and awkward. Many parents of twins carry one seat at a time, use a stroller frame or double stroller from the car, or leave carriers in the car and carry babies in their arms or carriers. Lighter carriers make a big difference. Consider handle comfort and the weight of each carrier with a baby in it.

Moving twins to convertibles

Twins may outgrow infant seats at different times. When you move to convertibles, look for seats that fit side by side, have high rear-facing limits and install easily in your vehicle. Narrow convertibles make room for a third passenger or another car seat later. See rear-facing toddler seats and narrow car seats.

Budgeting for multiples

Two seats, two bases or more, and possibly a double stroller add up quickly. Value-oriented seats meet the same federal safety standards as premium seats. Some manufacturers and retailers have multiples programs or discounts; ask. Avoid used seats unless you know their full history. See used car seat safety.

Premature twins

Twins are more likely to be born early and small. Choose infant seats with low minimum weights and good fit for small babies, and ask the hospital about a car seat tolerance test before discharge. See preemie discharge test and best preemie car seats.

Installing two seats side by side

When installing two seats next to each other, install one fully, then the other, checking that each is secure and that one seat doesn't press against the other in a way the manuals prohibit. Make sure buckles remain accessible and seat belts aren't trapped. A CPST can check both.

Infant seats for twins: what to look for

Look for infant seats that fit newborns well, since twins are often smaller at birth, with low minimum weight ratings and newborn inserts included by the manufacturer. Easy-install bases with clear indicators help when you're installing two. Consider the carrier's weight and handle comfort, and whether it's compatible with double strollers you like. Canopies help when you're juggling two babies outdoors.

Convertible seats for twins: what to look for

For convertibles, prioritize fit in your vehicle with two seats side by side, high rear-facing limits, and ease of installation. Narrow seats can leave room for a passenger in the middle or make three-across possible later with a sibling. Removable, washable covers are a plus with twins. Buckles that are easy to operate save time when you're buckling two children.

Travel with twins

Traveling with twins and two car seats is a big job. Lightweight seats, a double stroller that accepts infant seats, travel carts for convertibles, and help from another adult make it manageable. Consider renting baby gear at your destination for longer trips, while bringing your own car seats if possible.

Help and support

Many hospitals, CPSTs and multiples support groups offer advice for twin car seat setups, and some run inspection events. Other parents of twins are great sources of practical tips on carrying, installing and fitting two seats. Local parents-of-multiples clubs sometimes hold gear swaps; apply used car seat safety rules to anything secondhand.

Our bottom line

Choose seats that fit your babies and your vehicle side by side, are easy to install and manageable to carry. Lightweight infant seats paired with a compatible double stroller simplify the early months; narrow convertibles with high rear-facing limits carry you through toddlerhood. Get both installations checked by a CPST.

Keeping two seats clean

With twins, spills and messes double. Choose seats with removable covers that can be washed per the manual, and keep a small cleaning kit in the car. Clean buckles as directed to prevent sticky latches.
