Plantéa, Allé Desk & Allé Screen for Skandiform 2026 / September 10, 2026 by Kauppi & Kauppi

Plantéa by Skandiform 2026, design Kauppi & Kauppi

Flexibility in full bloom
At the heart of the Skandiform autumn 2026 collection is Plantéa by Kauppi & Kauppi - a new flexible modular system designed for the spaces in between, to adapt to changing needs and to encourage new ways to meet, work, and connect while bringing nature closer to people. Complementing Plantéa, the smaller green accessories Allé Mini Desk and Allé Mini Screen add greenery to workstations in a compact format, also designed by Kauppi & Kauppi.

Plant your creativity
Plantéa is a modular system that combines greenery, furniture, acoustic solutions, and space-defining elements. Designed to create new ways to sit, meet, and work while maintaining a light, airy expression. It defines zones without blocking light or creating visual barriers. Available as worktables, coffee tables, benches, dividers, desk screens, and green oases, all with self-watering pots, and with or without casters. Plant it, and watch it grow!

"Our new furniture collection Plantéa brings together tables, seating and space dividers with living plants. When greenery is given a natural place within the design, it naturally becomes part of everyday life, creating environments where people want to stay and thrive. Plantéa is based on the belief that every plant is an individual with its own specific needs, just like we are. That is why the collection is built around individual planting in separate pots, allowing each plant to be watered, rotated and cared for according to its needs." - Kauppi & Kauppi

Mini efforts with big impact
Allé Mini Desk and Allé Mini Screen bring nature closer to where people work and meet. Kauppi & Kauppi’s mini creations are designed to mount seamlessly onto tabletops or screens. A simple and effective way to integrate greenery and create a healthy, creative workspace. Easy to mount, move, and maintain. The mini way.

Solenne lighting collection evolves - Ifö Electric news 2026 / June 2, 2026 by Kauppi & Kauppi

Solenne is Ifö Electric’s most voluminous lighting collection, defined by its generous overhanging glass shades, casting a gentle gradient glow on its surroundings. Introduced in 2023 in collaboration with designer duo Kauppi & Kauppi. The collection includes several sizes and models for a variety of applications. Classic luminaires for ceilings, walls and facades with IP44 classification for both indoor and outdoor environments, as well as a grand pendant, a table lamp and Ifö Electric’s first floor lamp, both with wooden bases.

The Solenne collection is now complemented by a new lower glass shade, while a new more powerful LED module is simultaneously introduced. The new lower glass shade with a diameter of 360 mm, creates two new additional variants within the collection - a pendant version, and a flush mount luminaire for ceilings, walls and facades. The light remains soft, diffused and without harsh transitions. The Solenne collection is designed with larger rooms and public environments in mind, as well as interiors where comfortable light is essential.

“Solenne continues to evolve without losing its original identity. The new lower glass gives the luminaire a calmer and more floating expression despite its generous diameter to meet different needs, spaces and architectural contexts.“ - Kauppi & Kauppi

The newly developed high output 2500lm LED module is introduced in four new Solenne luminaires, featuring 360 mm diameter shades. Pendants with either high or low shade, and flush mounted luminaires with either high or low shade. All models can also be fitted with classic E27 retrofit light sources.

The Ohm silhouette in a larger scale - Ifö Electric news 2026 / June 1, 2026 by Kauppi & Kauppi

The first luminaries in the Ohm lighting collection were introduced in 2019, designed by Kauppi & Kauppi for Ifö Electric. The soft silhouettes with its signature interaction between porcelain and glass are inspired by historic insulators, rooted in the company´s long heritage. Over the years, Ohm has evolved into an award-winning and widely appreciated lighting collection. Finding its place in various settings from private interiors to larger architectural projects, in Sweden and internationally.

New variations and innovations have gradually extended the collection’s range of applications. From table lamps and splash safe pendants to ceiling and wall luminaries, as well as models mounted on arms for facades and bathrooms. The collection has newly been introduced in a brown glaze, alongside the classic white and black glazes.

The new Ohm 220 has a significantly larger scale than before, without losing its characteristic warm and welcoming expression. The increased volume allows the luminaries to incorporate more powerful lighting technology, enabling the Ohm collection to be installed in environments with greater lighting demands than previously possible. A lighting family equally suited for contemporary architecture as well as historic buildings.

“It is inspiring and a great privilege to work closely with a company as dedicated as Ifö Electric. Over the years, we have designed, developed and refined Ohm into a cohesive and versatile lighting collection. Taking the design to a much larger scale feels like a natural progression, allowing the new Ohm 220 to carry more light where it is needed, without losing its elegance. The light grows stronger, while the expression remains unchanged.” - Kauppi & Kauppi.

The new Ohm measures 220 mm in diameter, launched with two optional matt opal glass shades in different heights and characteristics. The lower version has a more concentrated and restrained appearance and is equipped with Ifö Electric’s new 2500lm LED module. The taller shade has a fuller expression and can be fitted with either classic E27 retrofit light sources or the new LED module.

Ohm Brown by Ifö Electric 2026 / February 19, 2026 by Kauppi & Kauppi

The Ohm lighting collection by Ifö Electric celebrates its seventh anniversary with the introduction of a carefully developed new brown glaze. A long-anticipated color, rooted in the company’s heritage and nature’s earthy tones. As the only manufacturer of pressed porcelain in Scandinavia, Ifö Electric has produced porcelain lighting in its own facilities for nearly a century. Now proudly presenting a new porcelain glaze with warmth and depth, introduced as the third standard color across the entire Ohm lighting range 2026.

Ifö Electric launched the Ohm lighting collection 2019, designed by Kauppi & Kauppi. The lighting family draws inspiration from the company’s manufacturing heritage and from the porcelain insulators first produced in the early 1900s. Its refined silhouettes and soft curves, expressed in both porcelain bases and glass shades, have been warmly received, embraced by architects, and recognized with design awards in Sweden as well as internationally.

Over the years, Ohm has grown into a comprehensive family, with new added lighting categories and an expanded range of applications. Today, the collection is a trusted lighting tool for architects, lighting designers, and interior designers seeking a harmonious balance of form, function, and modularity. From table lamps and pendants to ceiling and wall fixtures, as well as arm-mounted models for facades and bathrooms. Ohm offers a versatile program well suited for modern architecture as well as historical buildings. Until now, Ohm has been glazed in either white or black. In 2026, the collection will be available in a new, deep brown glaze, developed to echo the color historically used for landscape insulators. A natural and refined hue with a sophisticated luster - warm, rich and full of life.

“For the Ohm collection, the new tone is much more than just a color. It transforms how the luminaires are perceived and gives the fixtures a renewed expression. White provides a nearly neutral, floating lightness, while black adds weight and precision. Brown sits between the two, giving the luminaires a warm and embracing character that highlights their materiality - with a natural and friendly sense of authenticity. As designers, we are drawn to timber architecture and wooden interiors, and we envision how the new warm color, the light, and the soft porcelain shapes will come together in a truly special way within these settings”, says designers Kauppi & Kauppi.

KLOSS GO for Trece 2026 / February 3, 2026 by Kauppi & Kauppi

KLOSS designed for TreCe continues to expand - modular, adaptable and future-ready. Since its first presentation in 2023, KLOSS has grown into a comprehensive recycling furniture infrastructure. What began as a creative and adaptable system of steel modules has evolved into a scalable solution designed to meet every sorting need - large or small, permanent or temporary. KLOSS now forms an overarching recycling solution, accessible and usable in all imaginable situations. A system that responds to changing flows, new regulations and evolving interiors - without losing its clarity or character.

The new KLOSS GO launched by TreCe 2026, is a flexible add-on handle developed for KLOSS 360 (the original size) and KLOSS Small. Mounted onto configurations of four or six modules and combined with a new set of larger wheels, the handle transforms the system into a highly mobile sorting station. With its ergonomic grip and enhanced maneuverability, KLOSS GO introduces an additional layer of functionality. The larger wheels enable smooth transportation across longer distances, thresholds and rougher floor surfaces.

Where waste sorting needs to shift throughout the day - or where equipment must be gathered and stored after closing - KLOSS GO offers a seamless solution. Particularly suited for environments characterized by constant movement and reconfiguration, such as food courts, cultural venues and event spaces. Like all KLOSS accessories, GO is fully compatible with both existing and new modules. Customers who already integrate KLOSS into their recycling infrastructure can easily upgrade their current units into mobile sorting carts - extending functionality without replacing the system.

“KLOSS is a creative waste-sorting system designed to be configured and combined in endless variations and sizes, adapting effortlessly to a wide range of contexts and situations. Our new KLOSS GO add-on makes the system truly mobile! A softly flowing handle and generously sized wheels allows the units to be moved with ease and to be positioned exactly where needed at any given moment, whether that’s in the next room, on another floor, or outdoors. KLOSS GO is a mobile station with substantial capacity for multiple waste categories, ensuring that recycling always feels simple, accessible, and close at hand!”

New Classic Hallway Collection for Essem Design / February 6, 2025 by Kauppi & Kauppi

New Classic by Essem. Design Kauppi & Kauppi 2025.

Essem Design invited Kauppi & Kauppi to expand the company’s design legacy with a collection of new contemporary designs inspired by the iconic CLASSIC hat rack created by Gunnar Bolin in the late 1950s. The New Classic Collection designed by Kauppi & Kauppi for Essem was presented and launched at Stockholm Furniture Fair 2025.

“Designing new pieces inspired by the CLASSIC family for Essem felt like a good and fun challenge. The hat rack is such an iconic and recognizable item with its simple, straightforward form, made from bent metal tubes and a flat net. Our design take has been to contribute and expand the range with entirely new and independent designs, utilizing some of the materials and dimensions - but also add something new, pointing in a new direction” says Kauppi & Kauppi.

The New Classic Collection 2025 by Kauppi & Kauppi for Essem Design includes several categories such as a slender freestanding coat stand with an airy bow-like top, an efficient hook loop nodding to the 50s hat rack by its shape, a slim minimalist knob strip, and a hallway mirror with extra knobs for a key chain or other essentials. And of course, the knob wall mounted, available in two sizes. All five new designs are produced locally in south Sweden and available in several colors, lengths and versions.

Allé Mini - A Lush Biophilic Planter for Skandiform / February 3, 2025 by Kauppi & Kauppi

Allé Mini by Skandiform. Design Kauppi & Kauppi 2025

Allé Mini designed for Skandiform 2025 is a new smaller version of the much-appreciated floor standing plant divider Allé, launched in 2020. Allé Mini represents a new category in the greater Allé family and can be placed directly on tables, sideboards or in window niches to achieve a lush atmosphere. The Mini collection is available with one, two or three pots.

The elevated Allé Mini design creates a light and airy feeling, without heavy shadows, and protects table surfaces from condensation, while the long-time watering insert offers effortless individual plant care. Allé Mini allows the use of "hanging plants" and makes it easy to turn the plants for an even grow when needed. Allé Mini by Skandiform can be used to divide large working tables into temporary sections or to frame a space in greenery – a design that invites creative lush arrangements on tables or any other horizontal surface.

“We love lush biophilic elements in all kinds of interiors – public spaces, offices and homes. Living plants increase both serenity and creativity, something we believe is more important than ever to fill our shared spaces with. Allé is a family of functional space dividers for plants, designed to enhance good values in interiors. - Kauppi & Kauppi

Ohm Wall for Ifö Electric / March 5, 2024 by Kauppi & Kauppi

Ohm Wall by Ifö Electric is a splash safe addition to the appreciated and award-winning Ohm family, and Ifö Electric´s first fixture mounted on arm. A luminaire developed to harmonize with modern architecture, as well as turn-of-the-century buildings, houses and homes. The Ohm collection with its soft curves and restrained silhouettes is designed by Kauppi & Kauppi, honoring the company’s modular approach and unique manufacturing since 1934.

Ohm Wall with its emphasized vertical expression mounted on arm, adds a new motif and lighting archetype to the company range. The luminaire is elegantly drop-mounted to an extended metal arm, highlighting the porcelain, and bringing out the very best of the high gloss glazed durable material. The new metal component is sand casted in recycled aluminum, casted in Sweden. Porcelain fixtures are renowned for their exceptional durability, making them ideal for reuse. Since the 1960s, Ifö Electric luminaires have been designed with modularity in mind, allowing all technical components to be disassembled, cleaned, repaired, or upgraded - an adaptability that ensures the fixtures can keep up with the evolving lighting technology and remain relevant over time.

“Our vision was to design a lighting collection that can stand the test of time and adapt to all types of styles, beyond trends. A silent but clear whispering design that is functional, modular and responsive. We have been longing for the new Ohm Wall and the light qualities that comes with the verticality, and we are happy to see the combination of the long-lasting porcelain, illuminated glass and sand-casted aluminum complement and contrast each other.” - Kauppi & Kauppi

KLOSS Small & KLOSS Mini for TreCe / February 5, 2024 by Kauppi & Kauppi

KLOSS Collection 2024 by TreCe, design Kauppi & Kauppi.

Our award-winning KLOSS recycling furniture designed for TreCe, extends with two new smaller module sizes and several new features - and levels up from being a modular collection to a greater recycling furniture infrastructure. The new 2024 additions KLOSS Small and KLOSS Mini enables waste sorting everywhere - from the largest spaces and interiors to smaller and closer situations. The smaller KLOSS sizes fit well into all kinds of contexts where sorting furniture are needed, even where space might be limited or where the bins need to harmonize with the overall interior style. KLOSS can blend in or characterize a space depending on the choice of size, composition, color & accessories.

KLOSS Small and KLOSS Mini by TreCe are well-suited for placement adjacent to work desks, beside or under tables, on walls and in between furniture. A completely new accessory for the KLOSS system is the frame stand, designed to group and elevate small friendly sorting stations without heavy shadowing. Suitable as freestanding islands in hallways, or as small recycling units next to sofas, lounge chairs and benches in seating areas. KLOSS Small and Mini may be wall-mounted individually or lined up in rows on slender steel brackets, mirroring the option also available for the larger KLOSS bins.

“The new KLOSS sizes are designed to be close and accessible in every daily situation – preferable within an arm’s reach. The new neat versions are designed for sorting things that are either smaller or waste that is collected at a much slower pace, like batteries or lightbulbs. Our vision is that there shall be no space too small for sorting with KLOSS, and these new containers are tiny and cute enough to fit in anywhere.” - Kauppi & Kauppi

The lid program for the new KLOSS Small and Mini models includes fixed soft-closing tops and lids. In every unit there is an integrated bag holder and an additional choice of an inner container in 100% recycled plastic, to prevent leakage or to minimize the use of extra bags. Each module can be used singly or in creative groups. Connected modules can easily be regrouped into new formations at any time. The KLOSS modules are prepared for an interchangeable base program containing adjustment feet, legs, wheels, elevating frame stands and wall mounting brackets. The entire KLOSS system is powder coated in 11 optional standard RAL colors, or in any custom RAL. All parts can be disassembled and repaired, refreshed, refurbished, replaced & recycled.

Arkiv Hardware Collection by Byggfabriken / January 1, 2024 by Kauppi & Kauppi

Arkiv by Byggfabriken is a new series of fittings with slender handles and knobs that blend tradition with contemporary design, comfortable to grip. Arkiv is designed by Kauppi & Kauppi as a contribution to modern building conservation and a design interpretation of the Byggfabriken brand, founded 26 years ago as a traditional hardware store. Today a leading expert within Swedish building preservation and a “go-to” resource for knowledge and life-style inspiration. The shared love and passion for materials, details, and history laid the foundation for the collaboration and the design work on the new hardware series Arkiv.

“Arkiv has softly rounded curvatures that meet fingers and hands in a pleasant and friendly manner. The tactile values of an object, and the care for those who interact with our design, are fundamental for our design studio. We can often intuitively perceive if an object feels comfortable to grip, just by looking at it. But most important and above all, it will immediately be revealed through the hand as soon as you grab hold of the item. Arkiv is intended to be a fitting collection that you want to hold onto daily, and glad to rest your eyes on for many years to come.“ – Kauppi & Kauppi.

The hardware collection includes rear-mounted pull handles in three different lengths and two knobs, with or without base. The collection is performed in two versions: traditional golden brass or white metal nickel-plated brass. The brass is hot-pressed, post-sanded, and finally gently polished by craftsmen. The fittings are exclusively manufactured by Byggfabriken.

Hedge – A Mobile Green Room Divider for Skandiform / September 15, 2023 by Kauppi & Kauppi

Hedge by Skandiform, design Kauppi & Kauppi 2023.

Hedge designed for Skandiform is a room divider for living plants, allowing nature and greenery to be an integral part of indoor landscapes. A lush interior element that combines multiple functions into a mix of plant furniture, room divider and a mobile acoustic solution contributing to a better acoustic environment. The practical planting pots with long-term watering inserts allows individual plants to be easily cared for, refreshed or replaced when needed.

"Our first design project for Skandiform was Allé - a large family of plant dividers inspired by the characteristic willow alleys that define the landscape of south Sweden. The new room divider Hedge also draws inspiration locally from one of our hometowns Malmö, called the city of parks. The idea for Hedge was born during a spring walk in one of the parks, and the impression of the flower lined paths, leafy groves, and open spaces surrounded by tall vertical walls of greenery, later resulted in Hedge - a piece of furniture that brings the pleasant park feeling into our indoor environments." – Kauppi & Kauppi

The mobile green room divider Hedge by Skandiform is designed to create directions and natural zones in all types of environments. A flexible piece of furniture that can be arranged and repeated in creative formations. The lower part of the furniture contains a sound absorbing structure, while the flourishing plants on top of the furniture provide a pleasant, sound diffusing indoor garden atmosphere.
