Adjustment / rotation / tilt / mobility / storage features
| Fixed non-reclining seating configuration | Seats and backrests are permanently welded and bolted to the central frame at a fixed 105-degree ergonomic angle, no tilt or recline adjustment to minimize maintenance in high-traffic areas | |
|---|---|---|
| Perforated panel ventilation design | Uniform perforations across seat and back surfaces allow continuous air circulation, preventing heat buildup for users during extended waiting periods | |
| Floor level adjustment | Threaded adjustable feet at each leg end rotate to compensate for up to 15mm of uneven floor height, keeping the bench stable without rocking | |
| Anti-tip stable base design | Wide 680mm four-prong leg footprint exceeds public seating stability requirements, preventing tipping when users lean against armrests or seat edges | |
| High-traffic easy-clean surface | Smooth polished stainless steel and powder-coated surfaces can be disinfected with standard commercial cleaning products without staining or surface damage | |
| Outer armrest support | Curved armrests at both ends provide upper body support for seated users and define the seating boundary, no intermediate armrests to maximize flexible seating space | |
| Noise-dampened seat connections | Rubber spacers between adjacent metal seat units eliminate metal-on-metal friction and impact noise during use, reducing ambient noise in waiting areas | |
| Floor protection design | Non-marking rubber pads on all feet prevent scuffing and scratching on tile, terrazzo, and polished concrete flooring common in public spaces | |
| Tamper-resistant construction | All structural bolts are installed on the underside of the bench with no exposed fasteners on user-facing surfaces, preventing unauthorized disassembly in unsupervised public areas | |
| Recline Angle / Lock Reference | 125° with 3suggested lock positions | |
| Tilt Tension User-weight Range | Reference adjustment coverage 120 kg | |
| Height Adjustment Stroke | 100 mm continuous travel |
