Seat foam density is 50-55kg/m³ (480×460×120mm) and back foam density is 45-50kg/m³ (730×470×150mm), both with antibacterial properties. The dual torsion spring return mechanism provides silent, smooth reset with rubber pads for noise reduction. The seat cushion includes an automatic return function. Armrests are crafted from imported solid oak (432×80×27mm), while the outer shell uses PP injection moulding and inner panels use 15mm bent plywood. The base stand is made of 1.8mm cold-rolled steel with electrostatic coating, and linen side panels offer added protection. Steel is robot-welded and armrest brackets are treated with anti-corrosion epoxy coating. Optional armrest customisation allows integration of interpretation or audio equipment. The humpback-whale-inspired grille design delivers a simple, elegant look suitable for high-end venues.
