In the round (stitch) chair by Luflic (Brent Cordner)
This chair was named after the technique of knitting sleeves or socks “In the Round.†In order to upholster a chair completely with only one knit sleeve, the tubular steel frame had to be formed in one continuous line that closes in a loop. Careful attention was paid to the seat so that enough surface area would ensure comfort. Thirty feet, or nine meters, of sleeve is required to upholster one chair.
