The present disclosure provides a chair in which attachment strength of a holding member and the chair is enhanced and an attachment state can be stably maintained. A legged chair includes a leg member, a support post connected to the leg member, a metal frame integrated with the support post, the metal frame forming a seated portion, an awakening device configured to awaken a seated person, a battery configured to supply electric power to the awakening device, an ECU that controls the awakening device, and a holding cover configured to hold the battery and the ECU. The holding cover is attached to the highly rigid metal frame.

A seat air-conditioning device is applied to a seat and includes a cushion material, an outer cover, a ventilation hole and a surface groove. The cushion material supports a back or buttocks of an occupant seated on the seat. The outer cover covers the cushion material and has perforation holes. The ventilation hole is formed at a portion of the cushion material opposed to the back or the buttocks of the occupant seated on the seat. The ventilation hole is configured to suction or blow air. The surface groove is formed at a portion of the cushion material which is adjacent to the outer cover. The surface groove is communicated with the ventilation hole and extends from the ventilation hole in a direction away from a location of the cushion material, at which a center of the back or a center of the buttocks of the occupant is placed.

An automatically adjusting comfort method includes measuring pressure applied by a user via a pressure-sensor array, determining a pressure profile based on measurements from the pressure-sensor array, comparing the pressure profile to a first limit, determining a cumulative pressure profile over a predetermined duration, comparing the cumulative pressure profile to a second limit, and adjusting one or more of a plurality of adjusting mechanisms configured to alter the pressure profile for increased comfort of the user when the pressure profile exceeds the first limit or the second limit. An automatically adjusting comfort system includes a pressure-sensor array communicatively coupled to a controller for determining a cumulative pressure profile over time, and a plurality of adjusting mechanisms configured to alter the pressure profile to increase a user's comfort, wherein the controller automatically adjusts one or more of the plurality of adjusting mechanisms based on the cumulative pressure profile.
