Designer Frank Rettenbacher has pared back the materials to maximise form and function, creating a lightweight, four-leg, stacking chair that meets all the requirements of today’s homes and work spaces. The S 243 has a clear, logical design: the two supporting back legs have a diameter of 25 mm, whereas the diameter of the front legs is a slimmer 18 mm. The front legs form one continuous visible line from the front side to where they meet and connect with the back legs, giving the chair its airy, lightweight appearance. The dimensions of the moulded plywood seat and backrest are balanced with those of the tubular steel frame. Different versions are available: the S 243 with moulded plywood seat and backrest, the S 243 SPV (fully upholstered seat, moulded plywood backrest) and the S 243 PV (fully upholstered seat, backrest with tacked-on flat upholstery on the front). The tubular steel frame comes in a chrome-plated version or powder-coated in a range of colours. ![Thonet S243 tomatenrot glaenzend Eiche klar 5er stapel 466b FF Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243_tomatenrot_glaenzend_Eiche_klar_5er-stapel_466b_FF_Litho.jpg)![Thonet S243 PV Eiche Remix3 933 Gest olivgruen glaenzend S243 Buche geb olivgruen 541b FF Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243PV_Eiche_Remix3_933_Gest_olivgruen_glaenzend_S243_Buche_geb._olivgruen_541b_FF_Litho.jpg)![Thonet S 243 Eiche schwarz RV 450b FF](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_schwarz_RV_450b_FF.jpg)![Thonet S 243 Eiche perlweiss seite 234b FF litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_perlweiss_seite_234b_FF_litho.jpg)![Thonet S 243 Eiche tomatenrot gl perlweiss 1545 147b FF](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_tomatenrot_gl__perlweiss_1545_147b_FF.jpg)![Thonet S 243 Buche TP239 Tomatenrot 503b Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Buche_TP239_Tomatenrot_503b_Litho.jpg)![Thonet S243 Nuss perlweiss 178b FF Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243_Nuss_perlweiss_178b_FF_Litho.jpg)![Thonet S 243 Buche geb olivgruen Gest RAL6003 glaenzend 158b FF Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Buche_geb._olivgruen_Gest_RAL6003_glaenzend_158b_FF_Litho.jpg)![Thonet S 243 Eiche tomatenrot glaenzend 289b](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S-243_Eiche_tomatenrot_glaenzend_289b.jpg) ![Thonet S 243 Eiche sw 170b FF](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_sw_170b_FF.jpg)![Thonet S243 Buche olivgruen S243 SPV Eiche Remix3 933 Gest glaenzend RAL6003 1545 261b FF](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243_Buche_olivgruen_S243SPV_Eiche_Remix3_933_Gest_glaenzend_RAL6003_1545_261b_FF.jpg)![Thonet S 243 Gest RAL3013glaenzend Buche TP 239 Rostrot geb Eiche FF 520b litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_GestRAL3013glaenzend_Buche_TP_239_Rostrot_geb_Eiche_FF_520b_litho.jpg)![Thonet S 2439 FS0 1](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet__S_2439__FS0_1.jpg)![Thonet S243 PV S243 SPV Buche Hallingdal 65 103 1545 110b FF](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243PV_S243SPV_Buche_Hallingdal_65_103_1545_110b_FF.jpg)![Thonet S243 Buche geb RAL6003 Gest olivgruen glaenzend 1545 183b FF Litho](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S243_Buche_geb._RAL6003_Gest_olivgruen_glaenzend_1545_183b_FF_Litho.jpg)![Thonet S 243 Eiche TP29 1545 sw 37b FF Litho fr](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_TP29_1545_sw_37b_FF_Litho_fr.jpg)![Thonet S 243 Nussbaum chrom HT](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Nussbaum_chrom_HT.jpg)![Thonet S 243 Eiche sw Buche TP239 tomatenrot Buche geb olivgruen Gest RAL6003 RAL3013 glaenzend 438b Litho FF fr sch](https://www.stylepark.com/assets/transformations/manufacturers/_697xAUTO_fit_center-center_none/Thonet_S_243_Eiche_sw_BucheTP239_tomatenrot_Buche_geb.olivgruen_Gest_RAL6003_RAL3013_glaenzend_438b_Litho_FF_fr_sch.jpg) ![S 243 tubular steel chair](https://www.stylepark.com/assets/transformations/manufacturers/_1410x940_crop_center-center_none/Thonet_S_243_Eiche_sw_BucheTP239_tomatenrot_Buche_geb.olivgruen_Gest_RAL6003_RAL3013_glaenzend_438b_FF_FINAL.jpg) -
