Affordable, practical and lightweight. The versatile little number sits comfortably in tiny apartments around the world and effortlessly fits through doorways -- with room to spare.

These are just a few reasons why Marcus Engman, Ikea's Head of Design, named one piece of furniture his "favorite Ikea product of all-time." In an interview with Business Insider, Engman revealed his adoration for the Klippan loveseat.

"You can change its color and live with it for a long time," Engman tells Business Insider. Ikea also releases limited-edition covers for the loveseat each year, so it's easy to update its look. Or perhaps you prefer a Union Jack couch or black-and-white striped loveseat? You'll find a plethora of Etsy shops with Klippan covers for sale.

A short history of Klippan

First released in 1979, the loveseat is still one of Ikea's most popular items today. It's named after the the Klippan Municipality in Southern Sweden. (Fun fact: All Ikea sofas, armchairs, chairs and dining tables are named after places in Sweden.)

The small-sized sofa is available in multiple colors and runs $249 to $299 depending on the material. Since the first iteration of the wood-framed loveseat, Ikea has incorporated more affordable and lightweight materials into its design. The current iteration of the Klippan features a plywood and particleboard frame, polyurethane foam upholstery and steel legs. Ikea began flat-packing the Klippan in 2004.

When Ikea opened their first U.S. store in Philadelphia in 1985, the Klippan cost $395, Apartment Therapy reported. By switching up the materials and reducing its shipping costs, Ikea has been able to cut the price by 40% over the past 30 or so years, Business Insider reports.

Another reason why Marcus Engman may be so smitten with this little loveseat? His father, Lars Engman, designed it. Marcus remembers his father bringing home multiple Klippan prototypes in the '70s. Lars collected feedback from his kids to improve the design. "I have a lot of fond memories with that sofa, and I'm glad that it has survived for so long," he said.

It's safe to say that Engman knows Ikea's range of products well. He started working for the company as a 16-year-old pushing carts. At 18, he became the personal assistant to Ikea's seniors designers. After leaving for a few years to start his own agency, Engman returned to Ikea as head of design in 2013. Since then, he's been on a crusade to revamp Ikea's reputation by merging high-end design values with affordability.
