Back support on a floor seat usually means a backrest and nothing else, which leaves the lower spine unsupported at exactly the point it needs holding. This chair addresses that in two places at once. A lumbar pillow measuring 22 by 9 in fills the hollow of the lower back, and the backrest itself locks into six separate positions so the whole angle can follow a change in posture instead of forcing one. Setting that angle is done from the armrests: pulling an armrest releases the lock, and pushing it back engages the next position, which means the adjustment happens while still seated rather than by climbing off and reaching round behind. The armrests also give the elbows somewhere to rest, which a bare floor cushion never does. The seat cushion is not fixed to the frame either, so it lifts out and serves as a separate floor pad while the chair keeps its shape. Padding throughout is soft sponge, and the cover is a breathable linen-like cloth that lets warmth escape rather than sealing it against the back over a long stretch of meditation, reading, watching TV or playing video games. Inside runs a steel frame, the part that actually holds each locked position without gradual settling. Upright it takes 22 by 26 by 29 in and folds down to 27.5 by 26 by 14 in, weighing 21 lbs in total.
