Double Stroller vs Triple Stroller: Which One Fits Your Family?

Quick answer

For two kids, a double stroller like the Joovy Kooper RS2 gives you two full seats and a compact fold without the extra width of a triple. For three kids who all need to ride at the same time, a triple stroller is the only way to keep everyone seated. If your third child is older and can walk or use a ride-on board, a double stroller remains the easier daily choice.

Adding a third child changes the math on stroller space. A double stroller for two kids keeps your setup narrow and familiar, while a triple stroller for three kids adds a third seat and usually more length or width. The right pick depends less on the number of children and more on how many need to sit during a typical outing.

Joovy builds both double and triple options, plus a lightweight single stroller if you only need one seat. This comparison walks through the real trade-offs: seat count, folded size, weight, and how each fits into a car, a doorway, or a busy sidewalk.

Seat count and seating positions

A double stroller gives you two seats, which covers two kids riding at once. The Joovy Kooper RS2 Lightweight Travel Double Stroller has two roomy seats with independent reclines and included snack trays, so each child can rest or snack without disturbing the other. A triple stroller adds a third seat, but that extra seat often means a longer or wider frame that is harder to maneuver in tight spaces.

If your third child is a baby who cannot sit unassisted, a triple keeps all three contained. If the third child is a preschooler who walks most of the time, a double stroller plus a ride-on board or a parent organizer for your gear may be the more practical setup. Think about how often all three need to sit at the same time, not just how many children you have.

• Count how many kids actually ride on a typical trip, not the total number of children.
• Check whether your stroller can accept a car seat adapter if you have an infant.

Folded size and storage

Folded size is where double and triple strollers differ most. The Kooper RS2 is built to fold down compactly for a double, which matters if you drive a sedan or park in a garage with limited space. Triple strollers generally take up more room in the trunk and may need to be stored upright in a hallway or closet.

Measure your trunk opening and the space behind your third row before you buy. If you frequently fly or take public transit, a compact double like the Kooper RS2 is easier to gate-check and lift. A triple is better suited to families who mostly travel by car and have room to spare.

• Test the fold with one hand if you often hold a baby or a toddler's hand.
• Keep a rain cover and a parent organizer packed so you are not searching for them at the last minute.

Weight and pushing effort

More seats usually mean more frame, so triple strollers tend to be heavier and harder to push uphill or over curbs. The Kooper RS2 is designed as a lightweight travel double, which keeps pushing effort lower for two kids. If you are comparing a double stroller vs triple stroller for daily walks, the lighter option is the one you will actually want to use.

For active parents who jog, a dedicated jogging stroller like the Joovy Zoom 360 Ultralight is a better fit than either a double or triple for running. It weighs just 26.25 lbs and has a wide, stable frame, but it seats one child. Many families keep a single jogger for exercise and a double or triple for family outings.

• Weigh your kids plus your diaper bag and compare that total to the stroller's comfortable pushing range.
• If you run, choose a jogging stroller for workouts and a separate stroller for everyday errands.

Everyday maneuverability

A double stroller fits through most standard doorways and checkout lanes, especially a compact model like the Kooper RS2. A triple stroller may require wider aisles and can be difficult to turn in small shops or crowded sidewalks. If your routine includes narrow store aisles or older buildings with tight doors, a double is the safer bet.

Consider where you park and how far you walk. A triple works well for neighborhood walks and open parks, while a double is easier for errands, appointments, and public transit. If you only occasionally need a third seat, a double stroller with a ride-on board gives you flexibility without committing to a triple's footprint.

• Measure your front door and the narrowest aisle you use regularly before choosing a triple.
• A lightweight single stroller like the Joovy Kooper RS can be a good second stroller for quick trips with one child.

When a triple stroller makes sense

A triple stroller is the right call when three children need to ride at the same time on a regular basis. That includes families with twins plus a toddler, or three young children close in age who cannot be trusted to walk safely near traffic. In those cases, the extra size is a fair trade for keeping everyone seated and secure.

If you are considering a triple, check whether it accepts a car seat adapter for an infant. Joovy offers a Caboose RS and Caboose S Car Seat Adapter for Chicco and Graco seats, but it is compatible only with the Caboose RS and Caboose S tandem strollers, not the Caboose Graphite or other models. Confirm compatibility before you buy.

• Verify car seat compatibility if you plan to click an infant seat into your stroller.
• A triple is heavier and larger, so plan storage and vehicle space accordingly.

Trade-offs to weigh

• Seat count vs. footprint: A double stroller for two kids keeps a narrower footprint and is easier to push through doors. A triple stroller for three kids adds a seat but takes up more space in your trunk and on sidewalks. Choose a triple only if all three children need to ride at the same time regularly.
• Weight vs. capacity: Triple strollers are generally heavier and harder to push uphill. The Kooper RS2 is designed as a lightweight travel double, which keeps pushing effort lower for two kids. If you walk or use transit often, the lighter double is usually the more comfortable daily choice.
• Fold size vs. features: A compact double like the Kooper RS2 folds smaller for car trunks and closets. A triple may need dedicated storage space and a larger vehicle. Measure your trunk and storage area before committing to a triple.
• Car seat compatibility: The Joovy Caboose RS and Caboose S Car Seat Adapter works only with those tandem models, not the Caboose Graphite. A triple stroller may have its own adapter requirements. Check adapter compatibility for your specific stroller model before you buy.

Which size fits your family?

Best for

• Families with two children who ride at the same time and want a compact, lighter double stroller.
• Parents who frequently drive, fly, or use public transit and need a smaller folded size.
• Families with a third child who mostly walks or uses a ride-on board.

Not for

• Families with three young children who all need to sit during outings; choose a triple stroller instead.
• Parents who need three full seats and only have room for one stroller.
• Anyone who plans to jog; a dedicated jogging stroller like the Joovy Zoom 360 Ultralight is a better fit for running.

Pick the stroller that matches how many kids actually ride at once. A double stroller for two kids stays lighter and easier to store, while a triple stroller for three kids keeps everyone seated when walking is not an option. If your third child can walk, a double plus a ride-on board often gives you the best of both.
