Evenflo has issued a major safety recall affecting over 324,000 Revolve360 Slim car seats across the U.S. and Canada.
When Ben from Dadcar set himself the challenge of creating the world’s first six-seat Maserati MPV, we knew exactly how to help. His dream was simple: make memories as a family of six—without giving up the soul-stirring drama of a V8 Grand Tourer. Our job at Multimac was to make that dream practical, legal, and safe.
Here’s how we did it.
Ben’s goal was bold: fit four child seats across the back of a Maserati GranTurismo S, keep his wife up front, and head out for a proper family drive. He’d already proved you can daily a Maserati as a parent; this time, he wanted the full family in one row.
A custom Multimac 4-across unit, measured precisely for the GranTurismo rear bench.
Matching leather and blue contrast stitching to complement the Maserati interior.
A configuration that would grow with his kids: from newborn (with a MiniMac) through to 12+.
Before installation, Ben enlisted help to remove the rear cupholders and reshape the centre console trim. This small change created valuable legroom for the middle positions and lowered the centre section for better headroom.
Key tweaks:
Removed the cupholder module and reduced trim height.
Protected the wiring harness beneath with a tidy cover.
Preserved originality by using a spare console bought from eBay (so the car can be returned to stock at any time).
None of this is required for most cars, but on tightly packaged GTs, these micro-adjustments help maximise comfort for growing kids.
When our team arrived with the custom-trimmed Multimac, we all had the same reaction: it looked like it belonged in the Maserati from day one. The leather, twin stitching and blue thread matched beautifully—and, crucially, the seat slotted straight in.
Highlights:
Four-across layout securely mounted to the car’s existing seat belt anchorage system via the Multimac frame.
Headrests fitted to suit the ages of Ben’s children (configurable as they grow).
Option to add a MiniMac infant seat for newborns if needed.
Ben’s verdict? “It looks even better than I expected—and it fits perfectly.”
We know the comments section well: “How can this be legal?” “Is it insured?” “Is it safe?” Let’s cover it clearly.
Multimac is R129 compliant—the modern European child seat safety standard. Our system is different to single child seats, so it’s engineered with energy-absorbing structures that work for a very wide range of use cases: from one newborn to four older children across the same bench.
Developing Multimac to approval took 13 years and £750,000 of engineering and crash testing. The results are exceptional—good enough that even traditional child seat manufacturers struggled to believe the numbers when they first saw them.
DVLA: Because a Multimac is temporary and removable (in minutes), it doesn’t change a car’s official seating capacity. No V5C updates are needed.
Insurers: The Association of British Insurers reviewed our crash data and were satisfied. In practice, customers simply notify their insurer and keep the invoice for their records. When cars are written off or stolen, insurers routinely replace the Multimac as part of the claim.
A typical 4-across Multimac starts from ~£2,200 for the base unit.
With headrests and without a MiniMac, Ben’s spec works out at ~£2,600.
Add a MiniMac for infants and the package is ~£3,000.
Custom leather trimming (hand-finished, including stitching and thread colour choices) is £800.
Now compare that to four premium single seats over 12 years: parents buy an average of 2.8 seats per child. At £500 per seat, that’s ~£1,400 per child × 4 = ~£4,200—and you still may not get four-across compatibility. With Multimac, you keep the car you love and often avoid the huge depreciation hit of “having to buy a bigger car.”
With the seat fitted, the real test began: all four children belted in, Mum in the front, and off they went—even in the rain (because of course it rained). The kids loved the “matching Maserati seats,” and Ben loved that rear-row visibility and access were still workable in a tightly packaged coupe.
He’s already planning future tweaks (like relocating a wiring harness to gain an extra 1.5″ of headroom in the middle and adding a switchable exhaust valve—because Dadcar).
Families shouldn’t have to choose between passion and practicality. Multimac exists so you can keep the car that excites you—and still seat all your children safely, legally, and comfortably in one row.
For Ben, that means school runs, road trips, and memory-making in a Maserati GranTurismo S. For you, it could mean keeping your estate, SUV, hot hatch—or that V12 you swore you’d never sell.
Is a Multimac legal if my car is listed as a 4-seater or 5-seater?
Yes. The Multimac is a temporary, removable child restraint system. It doesn’t alter your car’s type approval or V5C. Just inform your insurer and keep your invoice.
Is it safe?
Yes. Multimac is R129 compliant and engineered with energy-management features for a wide range of children and scenarios. Our crash test performance is outstanding.
How long can my kids use it?
From birth (with MiniMac) to around 12 years and beyond, depending on size and local regulations.
How much does it cost?
From ~£2,200 for the base 4-across unit. Typical family setups (with headrests) are around ~£2,600; add MiniMac for infants and it’s ~£3,000. Custom leather: £800.
Will it fit my car?
Probably. We love a challenge. We’ve fitted Multimacs to everything from everyday family cars to super-saloons, SUVs—and now a Maserati GranTurismo.
Drop us a line with your make, model, and year, plus a photo of your rear bench. We’ll measure up, confirm compatibility, and help you design the perfect setup—from headrests to bespoke trim.
Keep the car. Add the seats. Make the memories.
