Reference year	2025
Name	Tiara chair with armrest
Technical purpose of product or process	Tiara is a Nordic design classic that is stylish and neat in expression. Tiara has a thick and good seat cushion and a design that makes you feel enveloped when you sink into the chair. At the same time, the slats make the furniture feel light and airy in the room. Tiara is ergonomically shaped, and the grip-friendly armrests make it safe and easy to use. • Slats in backrest • Upolstered seat • Removable back cushion • Wooden base • Chemical disinfectant ok (acid-cured varnish) • EPD (Environmental Product Declaration) • Møbelfakta
Classification	Class name : Hierarchy level EPDNorge: Furniture / Soft seating
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. 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.

¹This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
²The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
