      About The Brand

      A father and his dream

      Our legacy began in 1992, with a father's need to create a buggy with all terrain agility; to enable him to enjoy the New Zealand mountain trails with his baby. So with precision engineering, he crafted the foundations of Mountain Buggy’s legendary all terrain platform.

      The design and technology of our platform has evolved over the years to a deliberate design aesthetic influenced by clean lines and functional style.

      From newborn to toddler, the mountain trails to the city streets – Mountain Buggy enables parents to live 
      life without limit.

      Engineered for the mountains, designed for the city

      The original all terrain platform is Mountain Buggy’s legacy.

      Being the world’s first in a world class competitive market, Mountain Buggy is committed to staying ahead of the game, launching an all terrain revolution for the brand – making our products much more relevant to today’s modern parents, yet stays true to the brand’s authenticity and heritage.

      Through time, our team of leading engineers have continuously evolved this platform, cleverly incorporating the strength of our DNA across the range, ensuring ultimate engineering rigor runs across all of our premium, award winning products. Our DNA is built on manoeuvrability, durability, adaptability and simplicity.

      We take great pride in the craftsmanship of all the Mountain Buggy range, with a promise of maximum safety assurance and high performance delivery. Our team of professionals are conscientious in delivering well-crafted products, with a personal touch; from the tactile approach ensuring that the best materials and textiles are used, to the measured care taken when assembling the parts by hand, through to the final stages of packing the product safely into its custom made packaging to ensure a safe arrival to our customers.

      Customer connections

      Mountain Buggy believes in making strong customer connections around the world for our New Zealand brand and hearing valuable feedback from the people that matter – we listen, we develop, we deliver.

      “Our design philosophy is characterized by I LOOK, I GET, and I FEEL. We want parents to fall in ‘love’ with our products and our innovations, we want them to feel that they ‘get’ plenty of value whether it is function or performance, and then especially we want them to ‘feel’ great about the products ongoing use. We consider that a success in design, development, marketing, and sales.” Phil Brace, product development leader.
