Thank you for viewing. I purchased these wooden bed legs, M8, to replace the legs of a Muji sofa. Since the sofa had 5 legs, I bought two sets, and this is the remaining one for sale. Product Description: Wooden legs for leg-attached mattresses and bed frames. Compatible with "leg-attached mattresses" from February 2018 and "bed frames" from September 2018 onwards. Please be sure to refer to the FAQ for details. The leg-attached body (M8) corresponds to the old JAN 02509118 (natural, 20cm). https://www.muji.com/jp/ja/store/cmdty/detail/4550584410543?sc_cid=google_pla_pj_direct_cp_14797768044_adg_146642454856_cr_none_opt_online&gad_source=1&gad_campaignid=14797768044&gbraid=0AAAAABRJBpfrEjOKKbLD44QDZY4RjTz2S&gclid=EAIaIQobChMIo_ywkIDCkQMV6FwPAh2U-zAWEAQYAiABEgIf__D_BwE
