Mild steel is known for its strength and durability, making it a reliable choice for bed frames. Single beds typically accommodate a mattress that is around 36 inches wide and 75 inches long (90 cm x 190 cm). Make sure the MS frame you choose is designed to fit this mattress size. MS single beds without storage come in a variety of designs and styles. You can choose from minimalist, contemporary, or traditional designs based on your preferences and bedroom decor.
