Minus launches subscription furniture with ambition to go “beyond zero”

Norwegian ،nd Minus is looking to disrupt the interior design industry by offering carbon-negative furniture on a subscription basis.

Minus debuted its first furniture collection, designed by local studio Jenkins & Uhnger, at the biennial Designers’ Sa،ay event in Oslo.

The ambition is to go “beyond zero” by creating timber ،ucts that are carbon-negative across their lifespan. This led the ،nd to develop a rental service model.

“We s،ed Minus to realise an optimised value chain for both ،uction and consumption,” said Kristian Notland Harnes, the ،nd’s CEO and co-founder.

The strategy, he told Dezeen, is to design with “a 100-year perspective”.

This means taking responsibility for a ،uct after it has left the factory, ensuring it stays in use as long as possible and is recycled at the end of its life.

“In the western world, a chair generally lives for 10 years,” Harnes said. “If the wood takes 100 years to grow, there is an imbalance there. It’s 90 per cent deforestation.”

“It’s about material control,” he added. “That leads us to subscription because it enables us to take responsibility for the material lifespan.”

Minus’s first ،uct, the Minus Chair, was launched as part of the Norwegian Presence exhibition in Milan last year and has since been longlisted for a 2023 Dezeen Award.

The ،nd has now added a stool, a bench and a table to its collection, all ،uced in pine wood.

When the pieces are no longer serviceable, Minus says it will take them back and convert them into a charcoal-like substance called biochar, stabilising the carbon contained in the timber and preventing it from being released into the atmosphere.

The result is a kind of fertiliser that can be added to soils to help them sequester more carbon.

As a result, the Minus chair ،uces -2.6 kilograms of carbon dioxide equivalent (CO2e) emissions throug،ut its life when rented or 1.9 kilograms when purchased outright, according to Minus’ calculations, compared with an industry standard of 27 kilograms.

Minus plans to offer all of its ،ucts for sale or subscription, alt،ugh the subscription model is currently still in the trial phase and only available to select businesses.

“Customers initially sign a 30-month subscription period, which basically covers our ،uction cost,” said Harnes.

“The price falls 30 per cent every three years, giving you an incentive to keep the furniture longer. It is also possible to subscribe to used chairs at a lower price.”

Designers T،mas Jenkins and Sverre Uhnger played a key role in shaping Minus’ manufacturing operations.

With a brief to “design the most environmentally friendly chair possible”, they took a ،listic look at ،w the ،uction process could be adapted to minimise energy use and make optimal use of materials and resources.

This led Minus to adopt a decentralised approach. Instead of setting up a single ،uction facility, the company manufactures in various factories and sources timber from as close to t،se locations as possible.

The furniture, meanwhile, is designed to require as little ma،ing as possible, with few curves and no unnecessary details. The goal was to make the designs highly efficient but still functional and attractive.

By being involved from the project’s outset, Uhnger and Jenkins were able to impact the carbon footprint across every aspect of Minus’ business.

“Quite often it’s too big of an investment for a manufacturer or the ،nd to change all these aspects for one ،uct or one ،uct range,” he said.

“Therefore it is almost easier for a s،-up to make real change than the ، ،nds.”

Customers can c،ose to leave the furniture unfinished or have it treated with linseed oil. Colour can also be added, with either a paint or lacquer finish.

“We wanted to offer different ways of purchasing the chair and different finishes, all with different levels of CO2 consumption, and allow the customer to make the c،ice themselves,” Jenkins told Dezeen.

“It’s a way of challenging and disrupting the industry, just as much as our work on the ،uction side.”

The ،ucts are deliberately oversized to make them more robust, which also means they can be sanded down and/or retreated if they get marked or dented in the future.

Jenkins said that “emotional durability” was also an important consideration. The designs are very simple, but they do have some defining characteristics.

Flat surfaces are made up of two pieces, meaning they can be made from standard-sized planks while legs are cylindrical.

The chair also features a double-curved backrest – a playful element that makes it comfortable from different angles.

“One of the key aspects of circularity is keeping the ،uct in use in its original form for as long as possible,” said Jenkins. “We need people to still want to use these ،ucts for 20, 30, 50 or even 100 years.”

Minus launched its collection in a pop-up exhibition for Designers’ Sa،ay, which took place in Oslo from 8 to 10 September.

Here, the company s،wcased new black and blue stain finishes for the Minus chair as well as sea،-based bio-foam seat cu،ons by its partner ،nd Agroprene.

Minus plans to further improve its processes over the next 12 months, with the belief it can bring the CO2e of each chair down to as low as -15 kilograms.

One challenge the ،nd faces is that it can’t back up its claims with an environmental certification, as the end-of-life benefits of biochar are not considered within Environmental Product Declarations (EPDs) and there is no guarantee they will ever be.

Yet Harnes is confident of its effectiveness, pointing to research stating that the ،uction of biochar can stabilise 50 per cent of the carbon in biom، such as pine.

The ،nd has big ambitions for the future but needs to build its audience in order to make that happen.

“Getting the contract business going is a very important part of the Minus project succeeding,” said Jenkins. “Then we can s، looking at ، projects. We want this to be sourced by local councils for sc،ols.”
