SIHOO DORO C300L sedia da ufficio ergonomica in mesh nero

The SIHOO DORO C300L sets itself apart with a dynamic adaptive lumbar support that moves with your spine, paired with a breathable high-elastic mesh backrest and seat. Unlike static office chairs, this model combines a 4D adjustable armrest system and a sliding seat depth mechanism to accommodate a wide range of body types and working postures.

Highlights

• Dynamic adaptive lumbar support follows your lower back movements
• Breathable high-elastic mesh on backrest and seat for all-day comfort
• 4D adjustable armrests (height, depth, width, angle)
• Synchronous tilt mechanism with 90–135° recline and tilt lock
• Aluminum alloy frame and base for durability up to 150 kg
• Silent PU casters suitable for hard floors

In daily use

The C300L adapts to your body rather than forcing you into a fixed position. The sliding seat depth adjustment lets you set the right thigh support, while the 2D adjustable headrest cradles your neck during reclined breaks. The Class 4 gas lift provides smooth height adjustment for users between 160 and 190 cm tall.
