Kate Middleton and Prince William were seen for the first time pushing a bespoke baby buggy at the Houghton Hall International Horse Trials in Norfolk in May. When the royal couple wanted to purchase the trendy ‘off-road’ three-wheeler it was not available in their preferred color of navy. However, the family, which made the buggy, made it to Kate and Will’s specifications.

The Nipper buggy by Out‘n’About, a British manufacturer, crated the one-off buggy for Prince George and Princess Charlotte. The couple ordered the pushchair when George was 18 months, just before it was announced that Kate was pregnant with Charlotte. The buggy features a matching carrycot, an ultra-lightweight aluminium chassis, 360-degree swivel front wheel, rear wheel suspension, pneumatic tyres, hinged, padded bumper bar, shopping pouch and retractable sun canopy.

The Bedfordshire-based company has been making off-road pushchairs for 15 years. It has now received lots of orders for the buggy from parents. But, the navy made-to-order buggy bought by Kate and William for their kids is not available for royal fans wishing to copy the couple.

Out‘n’About received a request via George and Charlotte’s grandmother Carole Middleton for the buggy. The latter had admired a Nipper used by a neighbor in Bucklebury, Berkshire for a long time. “We received an internet order for a raincover from Carole Middleton. However, some of the details weren’t correct, so we got in contact with Carole to confirm what she needed,” said Marie David, the sales and marketing manager of the company.

David said that Carole loved the all-terrain buggy and told her that her daughter and son-in-law liked one of the older colors -- navy. Out‘n’About produces buggies in a range of vibrant colors like red, blue, purple, green. The manager said they told Carole that they had no navy buggies left and that they would try and see if they had any fabrics left and build her up a new one, with all the new, updated features.

According to the manager, they received the order from Carole 18 months before Charlotte was born. About two weeks later they came to know that the Duchess of Cambridge was pregnant with her second child. Her PA at Kensington Palace, Natasha Archer got in touch and gave a go ahead for the bespoke buggy.

David clarified that the buggy was not a gift, but purchased by the royal couple at a special price for the bespoke version. The pushchair retails for 289.95 pounds. Meanwhile, Kensington Palace got in touch with Out‘n’About for matching bespoke carrycot which is usually priced at 130 pounds ($174.15).
