| Technical purpose of product or process | The Ester armchair is a contemporary reinterpretation of a model originally featured in Johanson’s product range during the 1970s. Inspired by a vintage armchair discovered in the company’s archive, the design preserves the generous and comfortable seating experience of the original, while incorporating a refined and updated aesthetic. Swedish designer Alexander Lervik led the development, carefully maintaining the original dimensions to ensure ergonomic integrity and seating comfort. The result is a sleek and elegant conference chair, constructed with a solid wooden frame and designed to offer both visual lightness and exceptional comfort, making it ideal for professional and public environments. This declaration focuses on an in-depth study of Ester 08-Wood The table on page 12 of this declaration provides the key environmental indicators for the other models within the product family |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. They represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on registered EPDs according to EN 15804, Ostfold Research databases, ecoinvent and other LCA databases. The data quality of the raw materials in A1 is presented in the table below. Fabric used in the calculation is Camira Oceanic, a 100% post-consumer recycled polyester A3 Data Collection (Production Phase) Data for the A3 module, encompassing the production phase, was collected in 2020. This data includes all relevant inputs and outputs associated with manufacturing processes. A4 Data Collection (Transport to Customer) Transport data for the A4 module was sourced from Trafa.se and reflects operations during the years 2021-2022. According to statistics from Trafikanalys, the average distance covered by a Swedish heavy-duty truck transporting furniture in domestic traffic was approximately 143 kilometers in 2022, with an average of 153 kilometers for the period 2012–2022. These values are based on representative industry conditions and account for the most recent data on logistics efficiency and route optimization. A5 Data (Packaging Disposal) For the A5 module, it is assumed that packaging materials are automatically handled and disposed of in alignment with standard waste management practices at this stage. This assumption aligns with typical end-of-life scenarios for packaging in regulated waste systems. Maintenance Data (B2 Module) Maintenance requirements are calculated based on typical cleaning scenarios over the product's lifespan, assumed to be 15 years: Vacuum cleaning: Energy consumption is calculated assuming a 900 W vacuum cleaner operating for 30 seconds per week over 15 years. Wet cleaning: Water consumption is estimated at 0.0005 m³ (equivalent to 0.5 liters) per cleaning session, with cleaning occurring once per week for 15 years. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
