Altaes

Sunon Altaes is designed for managers and executive workspaces that need presence and day-to-day comfort. As a luxury executive chair, it features a sophisticated silhouette and a modern executive design that blends style and function. The high-back structure and modern ergonomic support are tailored for managers, while the three-stage cushion uses soft, medium, and firm foams to support long periods of sitting. Details such as the diamond-shaped handrail, genuine leather armrest cover, and finely controlled surface roughness contribute to a more considered feel in both appearance and touch.

When your hands keep returning to the armrests

Armrests are one of the chair areas you notice repeatedly because your hands and forearms return to them throughout the day. Altaes uses a diamond-shaped handrail made of the same material as the cylinders of luxury cars, with a fatigue life 100 times that of standard, plus 20% higher surface hardness, and 20% stronger wear and corrosion resistance. The surface roughness value is no more than Ra0.05μm, and the armrest is covered with genuine leather for a warm and soft feel. In buyer terms, this is a touchpoint designed to combine refined feel with durability-focused material performance.

When long desk hours start showing up in your seat

A chair can feel acceptable at first, then become distracting by the middle of the afternoon. Altaes addresses that with a three-stage cushion that uses 60N, 85N, and 135N foams across the front, middle, and rear of the seat cushion. Those different foam hardness levels work with a 15° sloping edge to relieve pressure and stand intense usage, while the overall mix of soft, medium, and firm foams is intended to provide long-lasting comfort. For a buyer, that points to a seat built for repeated daily use rather than a single uniform feel from front to back.
