Adjustment / rotation / tilt / mobility / storage features
| Seating support | Fixed cantilever sled design, no swivel, height adjustment or tilt, provides gentle flex for dynamic seated comfort | |
|---|---|---|
| Fixed arm support | Integrated curved upholstered armrests fixed permanently at 210mm above seat surface, aligned to standard 750mm desk height to support neutral forearm posture during meetings | |
| Ergonomic back support | Contoured two-section backrest with horizontal seam defining a built-in lumbar curve at 220mm above seat, supporting upright seated posture during 2 hour meeting sessions | |
| Floor protection | Non-marking glides on all base feet allow smooth repositioning on hard floors without scratching | |
| Cantilever flex | Chrome steel frame provides ~10 degrees of controlled backward flex under seated load without mechanical tilting mechanism | |
| Use case flexibility | Fixed design requires no user adjustment, ready for immediate use in meeting or guest seating | |
| Seating support behavior | Fixed cantilever sled base design, no swivel, height adjustment, casters or tilt mechanism; steel frame provides 12 degrees of controlled backward flex under seated load to reduce static sitting pressure without mechanical adjustment | |
| Floor protection and repositioning | Non-marking rubber-padded nylon glides on all four base contact points allow quiet repositioning on wood, tile, and vinyl hard floors without scratching or leaving marks; glides produce minimal noise when chairs are shifted under tables | |
| Anti-tip stability | 610mm front-to-back sled floor contact span prevents tipping during normal rearward leaning, eliminating need for rear anti-tip protrusions that catch on carpet or flooring gaps | |
| No-assembly use preparation | Chairs are shipped nearly fully assembled, only requiring minor glide fitting or bolt tightening before deployment for immediate guest/meeting use | |
