The Viral Car Seat: Why Multimac Keeps Breaking the Internet

In March 2025, a video of a Multimac fitted into the back of a Maserati passed 4 million views. A version showing the same seat in a Tesla picked up 6 million. A third video, walking through how the seat actually protects three children at once, passed 9 million.

That’s not a lucky clip. It’s three different videos, three different cars, three different angles, all landing the same way. The common thread isn’t the editing or the car or the platform. It’s that Multimac is the only product that does this, and most people watching have never seen anything fit three child seats properly into a car that small.

There’s nothing else to compare it to

Show someone a clever phone mount or a folding pushchair, and they’ll mentally place it against five competitors they already know. There’s no equivalent moment for Multimac, because there’s no second product in this category. A bench that holds three or four children, aged 0 to 12, anchored straight into the car’s chassis rather than relying on ISOFIX points, doesn’t exist anywhere else.

So when people see it fitted into a Maserati or a Tesla, they’re not comparing it to another brand’s version. They’re seeing a problem solved that they assumed had no solution. Most parents of three have already worked out, the hard way, that a normal back seat takes two child seats comfortably and turns the third into a daily negotiation. Multimac removes that problem entirely, and the videos are the first time a lot of people have seen that demonstrated rather than just claimed.

The safety video proves the same point a different way

The Maserati and Tesla clips work through surprise. The 9 million-view safety video works because it answers a question parents are already asking with real stakes attached: does this actually keep three or four children safe in one unit, or is it a compromise dressed up as a solution?

There’s no compromise to point to. Multimac is compliant to both R129 and ECE 44-04, and the chassis anchoring is the reason it can hold multiple children securely without depending on each car’s individual ISOFIX layout. Once that’s shown clearly, the video stops being a curiosity and becomes useful information, which is exactly why it outperformed the car-based clips. People weren’t just watching, they were deciding.

Why has nobody else built this?

The honest answer is that fitting three or four children safely into a single unit, in any car, is a genuinely hard engineering problem, not a marketing gap. Multimac’s been refining this since manufacturing began in 2008, and the chassis-mounted approach exists because ISOFIX points were never designed with three-plus child seats in mind.

That’s the reason the videos keep working. Nobody’s reacting to clever camera work. They’re reacting to a real gap in what’s available, closed by one product, shown doing the thing it does. A surprising car gets the click. The fact that nothing else on the market does this is what makes people stop, watch, and share it with the friend who’s been complaining about exactly this problem.
