This study explores the use of chairs during remote work from home. In our modern, digital society, it is becoming increasingly common for people to do their work from the workplace at home. Working from home has also increased significantly with the COVID-19 pandemic that has been a part of our everyday life for the past year. This work is based on the new conditions people are given when working moves full-time or part-time to the home and the new needs in the form of furniture and solutions that working from home requires. The problem discovered and explored in this work concerns limitations in existing and commonly used chairs when working at home. The problem was identified and explored in a research phase consisting of an interview study and a literature study. The interview study shows that the informants either have office chairs, they do not think aesthetically fit in the home environment or kitchen chairs with a lack of ergonomics are used. The literature study reveals additional information that many office chairs marketed as ergonomically correct are often overdesigned with complex settings that become difficult to use in real life, leading to people, despite advancing adjustment possibilities, sitting incorrectly or unfavorably from an ergonomic point of view. An additional problem concerns overcrowded people where there is no space for both the dining area and the office. Based on the problem formulation, the purpose of the work was formulated, which is to create an ergonomically well-adapted chair that acts as a hybrid between kitchen chair and work chair for people working from home. The aesthetics of the chair should fit in a kitchen environment in the home while fulfilling the ergonomic benefits of a work chair in the form of some adjustment. The interview study was conducted in the form of in-depth interviews with 11 informants, all of whom work full-time or part-time from home. Based on the Interview study and the literature study, several problems that may exist when using chairs, both adjustable and with fixed dimensions, as well as needs that arise during working from home were identified. The knowledge extracted from the research has laid the foundation for the idea-generating phase. In the generation of ideas, model building has in various ways been the tools used. Models have been made alternating either in metal, wood, cardboard or CAD. After that, a metal and wood chair were created with a stylish and light impression that meets good ergonomic possibilities for those who work from home. The chair can be adjusted in three joints with a few well-selected fixed dimensions. To solve an adjustment function while maintaining the aesthetics of the kitchen chair, it has fasteners in the form of magnets in the seat and back. It allows for an adjustment of both seat and back to suit the specific user. Height adjustment is also made using magnets inside sleeves that are attached to the underside of the seat leg and adjust the height of the chair. The magnets are designed to hold the sleeves in place on the seat leg. All adjustments are in fixed positions to make use easier for the user where the adjustments are quick to achieve. The result is a prototype of a chair that can act as a hybrid between kitchen chair and work chair. Keywords: Chair, remote work, working from home, ergonomics, kitchen chair, office chair.

Livscykelanalys (LCA) är ett verktyg för att analysera potentiell miljöpåverkan från en produkts livscykel. I studien undersöks vilka som är de mest betydande processerna och de mest utmär- kande potentiella miljöpåverkanskategorierna i livscykeln för Kinnarps kontorsstol 6110, samt vilka potentiella förbättringsåtgärder som kan utföras för förbättrad miljöprestanda. Analysen syftar även till att ge rekommendationer hur verktyget LCA kan implementeras i Kinnarps håll- barhetsarbete. Programvaran SimaPro från PRé, data från Ecoinvent och företagsspecifika uppgifter används i analysen. De huvudsakliga resultaten visar att störst miljöpåverkan åter- finns inom kategorierna ekotoxicitet, övergödning och naturlig landtransformation. Stolsmekanismen är den komponent på kontorsstolen som får störst genomslag i analysen till följd av sin stora massa och sitt höga stålinnehåll. Även ullklädseln får stort genomslag, vilket beror på produktionen av råull. I verkligheten bör denna påverkan vara större eftersom pro- duktionen av tyg från råull inte varit möjlig att inkludera. Vilket material som väljs för olika komponenter visar sig ha stor betydelse för livscykeln och LCA kan användas redan i konstrukt- ionsfasen för att rådgöra vilka val som ger lägst påverkan. En fördel med att bygga upp kompetens internt inom Kinnarps är att ökad kunskap om såväl metodiken LCA som produkt- sortimentet erhålls. Om Kinnarps väljer att implementera verktyget inom företaget har det även fördelar ur ett marknadsföringsperspektiv eftersom de då kan uppvisa detaljkännedom om sina produkters miljöprestanda. / Life Cycle Assessment (LCA) is a tool to analyze potential environmental impacts of a product's lifecycle. The aim of the study is to determine the most important processes and the most signif- icant potential environmental impact categories in the lifecycle of Kinnarps’ office chair 6110, and what potential improvements that can be made. The analysis also gives advice whether the tool LCA can be implemented in Kinnarps’ work with sustainability issues. The software SimaPro from PRé, data from Ecoinvent and company-specific data were used in the analysis. The main results show that the greatest impact can be found in the categories of ecotoxicity, eutrophica- tion and natural land transformation. As a result of its large mass and its high steel content the chair mechanism is the component in the office chair with the greatest impact. The wool uphol- stery fabric also has a major impact, which solely depends on the production of greasy wool. The impact is most likely larger in reality, since there is a lack of data regarding wool fabrics. What type of material that is chosen for different components turns out to be of great importance. LCA can be used as early as in the design phase to consult what material that gives the lowest impact. One advantage of establishing expertise in LCA within the company is that competence about LCA, as well as the product system, remains within Kinnarps. If Kinnarps choose to implement the tool within the company, there are also marketing benefits since they may present detailed knowledge of the environmental performance of their products.
