Rocking tension control lets the backrest give as much or as little as the sitter wants, and a pull lever locks it upright again for focused work. A 27.5" high back and a 19" x 18.5" seat follow the line of the spine, lumbar and hips, while a removable head pillow and soft-padded armrests take the pressure off neck and elbows. Faux leather with short pile plush over sponge covers a metal frame rated to 275 lbs. Seat height adjusts 19.5" to 23"; overall 26" x 24.5" x 45"-48.5". Net weight 31 lbs.
