A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The support material may form a chair back and/or a seat for the chair to provide support to the chair occupant. The support material may be made from a textile of interwoven strands wherein some of the interwoven strands include copper containing particles, such as copper iodide or copper oxide within the textile fibers.

A cable that protects an object includes: a sheath; and a cylindrical reinforcement member disposed inside the sheath and that surrounds the object. The cylindrical reinforcement member has a first side edge and a second side edge that extend in a longitudinal direction. The cylindrical reinforcement member is formed of a cable reinforcement sheet including: a first metal sheet; and a second metal sheet joined to the first metal sheet. A portion of the first metal sheet overlaps a portion of the second metal sheet, and the overlapping portions define a joint portion where the first metal sheet and the second metal sheet are joined. The joint portion is inclined, from the second side edge to the first side edge, toward the first metal sheet.
