The Three-Child Car Seat Problem: How We Solved It for Germany’s Top Car YouTuber

We traveled to Germany to install a revolutionary child seat system in CarManiac’s BMW iX. Here’s why this solution is changing how families think about car choice.

The Problem Every Parent with Three Kids Knows

Picture this: you’ve got three children, a beautiful car you love, and a mounting sense of dread every time you need to buckle everyone in. Most cars come with just two ISOFIX points. Even when you manage to cram three separate seats across the back row, you’re left with clashing shells, unreachable buckles, and a daily wrestling match that turns every journey into an ordeal.

The conventional wisdom? “Time to buy a van.”

But here’s the thing—not every family wants to trade their sleek SUV or sedan for a big, boxy van that’s less efficient, harder to park, and frankly, just not what they envisioned driving.

Enter Multimac: Engineering Elegance Meets Family Reality

That’s exactly why we found ourselves on a plane to Germany, tools in hand, ready to demonstrate something revolutionary to CarManiac—one of the country’s most influential automotive creators. His challenge? Fitting three children safely and comfortably in his stunning BMW iX M70 without sacrificing the car he actually wanted to drive.

The solution wasn’t compromise. It was Multimac.

Why the BMW iX M70 Made Perfect Sense

CarManiac’s choice of the iX wasn’t arbitrary. This isn’t just another electric SUV—it’s a masterclass in forward-thinking family transport. Spacious enough for real comfort, efficient enough for guilt-free long journeys, and with the battery range to handle proper road trips. Add a roof box and you’ve got a holiday machine that doesn’t scream “soccer mom van.”

The only missing piece? How to safely seat three children across the back without turning every car journey into a logistical nightmare.

The Multimac Solution: Simple Brilliance

What makes Multimac special isn’t just what it does—it’s how elegantly it does it.

Instead of fighting with multiple individual seats, Multimac is a single, precision-engineered bench that transforms your rear seat into a proper three or four-child seating solution. Here’s how the magic happens:

Rock-Solid Foundation
Heavy-duty tether straps anchor directly to reinforced points beneath your car’s rear cushion—not some flimsy surface mounting, but deep into the vehicle’s actual structure.

Precision Installation
The Multimac bench ratchets down to these anchor points with engineering-grade precision. It’s substantial enough to require two people to lift it in, but that weight translates to unshakeable security once installed.

Adaptive Seating
Individual headrests and harnesses adjust to each child’s height. Smaller children ride safely in integrated 5-point harnesses, while taller kids can use the car’s standard 3-point belts without any seat removal required.

From Birth to Big Kid
The MiniMac infant insert handles babies from birth to 18 months, clicking seamlessly into the main unit. One system, years of use.

Real-World Brilliance

The true test of any family solution isn’t the showroom—it’s the school run. Multimac excels where it matters most:

Space Without Compromise
Three or four children sit side-by-side in genuine comfort, not squeezed together like sardines.

Fleet Flexibility
With additional tether kits, the entire system transfers between household vehicles. Soccer practice in the SUV, weekend trips in the sedan—same safe seating solution.

Premium Materials
The trim quality matches luxury car standards because it literally uses the same supplier as Jaguar Land Rover. Custom leather and color matching available for those who demand perfection.

Clean Installation
Unlike bulky ISOFIX bases with support legs cluttering the footwell, Multimac sits flush across the existing bench, leaving clear exit paths and protecting your upholstery.

Safety: Where Engineering Meets Peace of Mind

Child seat safety isn’t marketing fluff—it’s physics, engineering, and rigorous testing. Multimac faces a unique challenge: protecting everyone from newborns to 12-year-olds in a single system.

The solution? Progressive energy absorption that works like a car’s crumple zone, managing impact forces across different body weights and sizes. A transverse beam distributes side-impact forces across all seating positions, while the entire system meets European safety standards recognized worldwide.

This isn’t just clever design—it’s crash-tested protection for your most precious cargo.

The Numbers: Investment vs. Compromise

A complete Multimac setup runs €2,400-3,000. It’s not pocket change, but consider the alternative: trading your ideal car for a van costs far more, both financially and in daily driving satisfaction.

More importantly, Multimac preserves choice. You keep the car you actually want to drive, whether that’s CarManiac’s sleek BMW iX or any other vehicle that captures your automotive passion.

The Verdict: Three Happy Kids and One Satisfied Creator

The real test came when CarManiac’s three children climbed into their newly transformed iX. No struggling with separate seats, no unreachable buckles, no compromises on comfort or safety.

Their verdict? Finally, a proper solution.

For CarManiac—and countless families who thought a van was their only escape from child seat chaos—Multimac represents something more valuable than clever engineering. It’s freedom to choose the car you love without sacrificing the family you’re protecting.

Sometimes the best innovation isn’t about accepting compromise—it’s about refusing to accept it at all.
