FLEMMING LASSEN was born in 1902 into an artist family in Copenhagen. His mother was a painter and his father a decorative painter. Flemming and his brother Mogens decided at an early age that they would be architects when they grew up. The Lassen brothers have been told to have used their pocket money on architectural books, and during their free time they would often study buildings around their neighborhood and make architectural drawings of them.

However, Flemming Lassen did not follow a traditional path to become an architect: he trained himself through apprenticeships. Lassen’s tenacity and passion for architecture brought the desired outcome, as through years of work, he managed to become a renowned architect without actually getting a degree in the subject.

The Tired Man lounge chair is an investment in timeless, high quality design. The armchair fits both by the fireplace and in the reading corner of the living room.

Lassen’s story is closely linked with Arne Jacobsen, considered to be one of Denmark’s best-known architects and designers. The Lassen brothers and Jacobsen learned to know each other already in the 1910s when they were studying at the same boarding school in Denmark. Their friendship continued into adulthood, as Flemming Lassen and Arne Jacobsen started an architectural firm together in the 1930s and designed several buildings and their interiors.

Flemming Lassen also designed many pieces of furniture during his career, the most famous one is probably the huge The Tired Man armchair. According to him, sitting in the chair should feel ”as warm and safe as a polar bear cub in the arms of its mother in the middle of the ice cap”. The design is based on an armchair, which Lassen designed for the Copenhagen Cabinetmakers’ Guild’s furniture exhibition in 1935. The chair was presented at the exhibition stand of Danish furniture carpenter A.J. Iversen.

The following year he made changes to the dimensions, and it was introduced by the name of Den Trætte Mand, later to be better known by its English name The Tired Man.

A.J. Iversen made less than 50 of The Tired Man easy chairs, of which one in particular has left its mark in the history books. In 2014, an original The Tired Man easy chair was sold at the Danish Bruun Rasmussen auction at the record price of 1.42 million Danish krone, or some 190,000 euros. The Tired Man was said to be at the time the most expensive armchair ever to be sold at an auction in Denmark.

By Lassen re-introduced The Tired Man in 2015 – to the joy of all lovers of classic design.

Flemming Lassen’s relatives established the By Lassen design brand in 2008, re-manufacturing small items and furniture by Flemming and Mogens Lassen. And to the joy of many people, The Tired Man easy chair and the ottoman were again available in 2015, enabling design lovers to get a piece of Danish design history into their homes.
