Product Information

About this item

• 【Adaptive Back Support】 From focused work and virtual meetings to study sessions, comfort starts with support that adapts to you. The dual-back design and adaptive lumbar support respond naturally as you change positions, helping keep your lower back comfortably supported whether you're leaning forward to focus or reclining between tasks.
• 【Designed for Flexible Spaces】 Ideal for home offices, apartments, bedrooms, and shared workspaces. The coordinated 3D armrests adapt to different sitting positions throughout the day, then flip up to let the chair slide neatly under most desks when extra space is needed.
• 【Comfort Through Long Hours】 Long hours at a desk can create pressure and heat buildup. The wide saddle-shaped seat helps distribute weight more evenly across the hips and thighs, while the breathable full-mesh design promotes airflow to help keep you cool, comfortable, and focused throughout the day.
• 【Made for Workday Breaks】 Between meetings, emails, and focused projects, small breaks matter. The adjustable headrest supports your head and neck as your posture changes, while the 110°–125° recline lets you lean back comfortably and relax between tasks without losing support.
• 【Built for Everyday Confidence】 Designed for daily use in home offices and professional workspaces, the SIHOO M59AS combines dependable stability with lasting durability. Tested to BIFMA and SGS standards and supporting up to 330 lbs (150 kg), it's built to deliver reliable performance day after day.
