British design studio Layer has aimed to bring sustainability to mattress design in a collaboration with Chinese start-up Mazzu, creating a modular, foamless product made up of textile-covered springs.

The Mazzu Open mattress was designed to have the comfort of a traditional sprung mattress while being adaptable, repairable and easy to pack down when moving house, so as to prolong the product’s life.

The design features row upon row of individually textile-wrapped pocket springs, which sit sandwiched between a base “matrix” and a cushioned topper to hold them in place.

All its components are either recyclable or biodegradable, and no glue was used in the construction of the mattress.

The structure — left open at the sides for a distinctive, utilitarian look — also has the benefit of being hygienic, according to the studio, as users can check the inside of the mattress and take it apart to clean every element.

The modular design of the mattress means buyers can treat the springs like “pixels”, choosing between three levels of firmness for each point in the matrix to create a support pattern of their choosing. This also allows couples to customise their own side of the bed.

Additional spring modules and a different base and topper can be added to change the size of the mattress, and the whole kit can compress down to around 80 per cent of its size when disassembled.

The mattress comes in a reusable packaging system, also designed by Layer, that sees it divided into small components and split across several cartons, each weighing less than 10 kilograms. The spring modules compress from 250 millimetres to 50 millimetres in height as part of this.

Layer founder Benjamin Hubert told Dezeen that the studio tried to tackle multiple problems with current mattresses in one go with Mazzu, ranging from the impracticability of transporting them to the lack of customisation.

“They are too bulky once you unpack them and they ‘inflate’ from their compressed shipped form,” said Hubert. “They contain huge amounts of foam, which is next to impossible to recycle, and for the most part you can’t pack them down again for storage or transport.”

The studio wanted to avoid using polyurethane foam, a common mattress material, because as well as being difficult to recycle, it is energy intensive to produce and generates volatile organic compounds (VOCs) that are harmful to health.

The material is technically recyclable, but most mattresses do not reach the scarce recycling facilities, and they are often discarded before their time. In the UK, for instance, around 6.4 million mattresses are thrown away each year — about one for every ten people — and only around 14 per cent of them are recycled.

Instead of foam, the Mazzu Open mattress’s hourglass-shaped springs are shrouded in a two-tone 3D-knit polyester sleeve. The other materials used are steel for the springs, ABS plastic for the connection system and wool for the topper. The wool is biodegradable, while all the other materials are recyclable.

Hubert describes Mazzu as “leading the way” in delivering sustainable, high-performance bedding, and says the companies worked together for three years through the pandemic.

They went through many iterations of the mattress design in that time, as the studio tried to find a connection solution that would be both simple and comfortable.

“We must have tried about 20 different connection techniques,” said Hubert. “We had to find an optimum size that could be calibrated to fit all the standard mattress sizes too — not easy given there are a lot of international sizes.”

“The system needed to be highly cost-effective by using the least amount of parts and the simplest connection feature,” he continued. “The design of the connection systems changed dozens of times as we tested strength, ease of use, noise and comfort — we had hundreds of springs in the studio at times!”

Other recent designs from the London-based design studio have included sustainable dog toys for Canadian company Earth Rated and a green hydrogen vehicle retrofitting system for US start-up Croft.

Mazzu and Layer launched the Mazzu Open mattress at the German furniture fair IMM Cologne, which was held from 14 to 18 January. See Dezeen Events Guide for an up-to-date list of architecture and design events taking place around the world.

Layer designs Croft system to power vehicles with hydrogen

Benjamin Hubert’s studio Layer has worked with US start-up Croft to design a system of products for retrofitting vehicles to run on green hydrogen.

The Nanoplant and Nanocartridges are the first prototypes from Croft, which is currently raising funds for the project, and enable users to produce their own solid-state hydrogen to power cars, trucks and other heavy-duty vehicles.

With an appearance similar to a large home battery, the Nanoplant uses electricity and water from the mains supply to carry out electrolysis — the splitting of water into hydrogen and oxygen.

The hydrogen obtained in this process is known as “green hydrogen” because, if it is produced using renewable energy, it creates no greenhouse gas emissions. This is in contrast to “blue hydrogen”, which is produced from natural gas and creates some emissions.

The Nanoplant contains a pull-out drawer with room for four Nanocartridges, which store the hydrogen by sticking it to the surface of a proprietary particulate. According to the brand, this method stores the hydrogen densely and at low pressure, making it a safe solution that also gives more power and range than electric batteries.

According to Layer, Croft is “dedicated to creating a blueprint for an enduring, scalable, green-hydrogen economy” and offers its technology at a much lower cost than other hydrogen storage solutions on or near the market.

The studio says the product is best suited for larger vehicles in environments with little fast-charging infrastructure, and that heavy-duty pick-up trucks for farming, forestry, construction and other industries are the first target.

“Batteries are great to decarbonise smaller passenger vehicles that get used in gentle, predictable ways with access to good charging infrastructure,” Hubert told Dezeen.

“However, lots of mobility applications don’t match that description, and there, we need a power source that is denser than batteries and has fewer dependencies on infrastructure,” he added.

“Hydrogen stores significantly more energy in less space and with less weight than batteries, and it’s much easier to use hydrogen in environments with weak grids or where charging otherwise isn’t available.”

Hubert said that, at least in the short term, hydrogen would be a complement to electric vehicle technology, not a competitor.

“It’s a great complementary solution to batteries, and as with all things, it’s important to pick the right tool for the right job,” he continued.

To retrofit a vehicle with the technology, Croft removes most of the components of the power train and replaces them with its hydrogen storage system, a fuel cell, electric motors and other components, while reprogramming the vehicle’s onboard computer to utilise them.

Layer led the design and engineering of the Nanoplant and Nanocartridges, endeavouring to make them straightforward and easy to understand while also giving them an aesthetic that would communicate robustness and technological prowess.

The Nanoplant is modular and infinitely expandable — additional Nanoplant modules can be connected horizontally, each with the capacity for four Nanocartridges.

Each module has a minimal user interface on its front that counts down the time left to complete the recharge, and there is also a hose module for on-board charging. The drawer containing Nanocartridges can also double as a cart for transporting them to the vehicle.

The Nanocartridges weigh 14 to 16 kilograms and have four side handles, creating a cubic frame that can be easily gripped and stacked. A circular indicator on the top surface shows the cartridge’s remaining hydrogen capacity.

According to Layer, each cartridge has a range of 20 to 80 miles depending on the size of the vehicle and how hard it works.

“In addition to rapid fueling, cartridges also allow operators to carry additional fuel with them or receive rescue fuel if an asset gets stranded in the field, two features that today’s battery vehicles lack,” said Hubert.

In addition to its product design work, Layer created the brand identity for Croft, including the brandmark and packaging.

The brandmark is based on an abstracted letter “H”, which has been stylised to also look like a road vanishing into the distance. It will be used in many ways, including debossed into products, applied as a micro-pattern to create texture, and as a call to action on interaction points.

Layer has been embracing emerging technologies, and has recently also worked on the Ledger Stax hardware wallet for storing cryptocurrency and the Viture One video streaming glasses.
