The Growing Family Dilemma

When you have 3+ children, you're faced with an expensive choice. Traditional car seats force families into vehicles they don't want—or need.

The 7-Seater Route

  • £15,000–£30,000 for a larger vehicle
  • Higher fuel costs (MPG drops significantly)
  • Increased insurance premiums
  • Larger parking footprint
  • Depreciation on a vehicle you may not need long-term
  • Still need to buy multiple car seats anyway

The Multimac Solution

  • From £1,895 for complete system
  • Keep your current car (and its efficiency)
  • One seat grows with all your children (0-12 years)
  • Aluminum frame—built to last decades
  • Professional installation in 60-90 minutes
  • Remove and reinstall in under 1 minute when needed

Average Family Savings

£18,000+

Over 5 years compared to upgrading to a 7-seater
(Includes vehicle cost, depreciation, fuel, and insurance)

Proven process across thousands of families

What parents are saying

“Great product and service from the Multimac team - just the solution we needed for our car so that we can ensure the safety of the kids having them all together in one row - also meaning the boot is free to fit in the buggy (and many other bags) which is an essential for us!”

Samantha Harris, London ★★★★★

“One of the greatest products we’ve ever purchased for our children! Cannot say enough great things about this company and their products. Genius on many levels.”

Tom Peterson, Cambridge ★★★★★

“Such a unique product - I just wish I'd found them when our 3rd originally arrived, and we wouldn't have had to change cars.....! Can't recommend the company and product enough. The kids love it (we did a European trip with the 3 across the back and there were zero complaints.....about the seat...!). Anyone I know that has 3 (or 4!) I recommend it to them.”

Pete Smith, Surrey ★★★★★

“We’re very happy with our Multimac - it’s nearly impossible to fit three child seats in a Renault Grand Scenic, and this solved the problem perfectly! There’s plenty of legroom, it’s easy to buckle up all three kids (even the one in the middle!), and they absolutely love it.”

Nejc Lokar, Slovenia ★★★★★

“Problem solved. How to fit three grandsons all in car seats with two adults... Multimac 1000 means we can have three grandsons (9 months, 4 and 6 years old) in the back seat of our Mercedes Benz Marco Polo campervan with two adults on the front seats... Excellent service, clear, easy fitting instructions, a very well conceived and engineered product. Most importantly, the safety aspects are top notch.”

Sary King ★★★★★

“Multimac was the only solution that allowed us to safely seat three children in the back of our car. The installation turned out to be easier than we expected. So far, the system has proven to be excellent. We are impressed with the build quality and comfort. We also want to praise the Multimac team for their responsiveness…”

An Ke ★★★★★

“An absolute godsend for our young family! Unexpectedly, we had twins back in 2020 (along with a three year old) and Multimac offered the exact service and equipment we needed, offering an easy and safe way to get all three toddlers into the back of our car.”

Dave Masterman ★★★★★

“So happy with our Multimac. Reached out to the team months in advance for a quote / info. The lovely team responded fast, provided so much info and honestly answered every question… Best seat we’ve bought and with 3 under 6, we’ve bought a lot of seats.”

Boo Farrell ★★★★★

“Perfect solution if you have three (or even four!) children and don’t want to buy a new car. We are absolutely convinced by Multimac and can highly recommend the seat. Great products and really good contact to the developer.”

Markus Zyprian ★★★★★

“We have a Vauxhall Astra and 3 children under 3 years old and everything we tried to seat all 3 in the rear seats didn't work… We then found the Multimac… We now have all 3 children seated in the back comfy and safe and I get to keep my car — brilliant, thank you.”

Dean Hooper ★★★★★

“3 kids 0/3/6 years – almost had to buy a van. Glad I found the Multimac and can keep my BMW X5. The product and quality looks really good so far. Easy to install – takes about 5 minutes to remove and put back (2 people) if needed.”

Josef Herz ★★★★★

“I'm a very happy customer. I ordered 2 and they're amazing. The leather feels amazing. My kids are super comfortable. It's obvious to me that these are much safer than standard car seats… It arrived quicker than the quoted lead time.”

Hamed Adefuwa ★★★★★

“Victoria was amazing going through the whole process. She answered all my questions beforehand… It was a very easy process from initial enquiry to getting the unit fitted. I absolutely love my Multimac! Kids love it — no more fighting about who sits where…”

Tej Panesar ★★★★★

“Great product and service from the Multimac team - just the solution we needed for our car so that we can ensure the safety of the kids having them all together in one row - also meaning the boot is free to fit in the double buggy (and many other bags) which is an essential for us!”
