"Designers are using thinner and thinner pipes for the structure [of furniture]," Herkner says in the movie. "I wanted to go the other way, so we selected a pipe diameter of about eight centimetres."
The seats and curved backrests are upholstered in a variety of different soft textiles to contrast with the metal frames. Herkner says he wanted to create a collection of furniture with personality.
"I'm not just a guy doing function, function, function," he explains. "I really want to add character to a product."
Herkner, who also designed an accompanying side table featuring the same wide tube, believes his design philosophy fits well with Moroso as a brand.
"I think my approach and the approach of Moroso is very similar," he says. "With Moroso I have the opportunity to make colourful, interesting, beautiful products. It's not just about the function. It's about giving a soul, a character, a personality to the product."
Pipe is Herkner's second furniture collection for Moroso, following a range of woven chairs called Banjooli for the brand's M'Afrique collection, which is produced by traditional craftsmen in Senegal.
His first product for Moroso was a series of baskets woven from paper yarn. Moroso creative director Patrizia Moroso spotted the baskets in Milan in 2011 and asked if she could produce them.
"That was the starting point," Herkner says. "Then she invited me to Udine and we chatted about art and everything to understand each other, which is very important in the beginning of a collaboration."
It is the latest in a series of movies about the Italian brand's 2015 products, which you can watch on our YouTube playlist:
