Overview
Why Choose EC200 Pro
The EC200 Pro is built for remote workers, programmers, and designers who need breathable support and precision adjustability throughout 8+ hour workdays. From the full-mesh seat that keeps air circulating to the 4D armrests that adapt to your posture, every detail is designed to help you stay comfortable and focused.
Full Mesh Seat: 100% high-elastic mesh promotes continuous airflow to prevent overheating, while providing flexible, supportive comfort. Unlike foam cushions, the mesh seat stays cool and maintains its shape through years of daily use.
4D Adjustable Armrests: Full 4D adjustability — up/down, forward/back, left/right, and 30° rotation. The wider PU surface (10" × 4") helps reduce shoulder tension and supports your arms whether you're typing, coding, or taking a call.
2-Way Lumbar Support: Adjust the lumbar 2.36" vertically and 0.8" in depth to fill your lower back curve and prevent slouching. The support stays with you whether sitting upright or reclined.
Sliding Seat & 3D Headrest: The 5-position sliding seat (1.97" adjustment) lets you match thigh support to your leg length. The wider 3D headrest (12.8" × 7.87") adjusts in height, depth, and angle to cradle your neck during breaks — keeping you comfortable without pushing your head forward.
4-Stage Recline & Tilt Tension: Lock the backrest at 90°, 105°, 120°, or 130° to match your activity — focused work, reading, calls, or relaxation. The adjustable tilt tension knob lets you fine-tune recline resistance to your preference. Fits users from 5'4" to 6'0" and up to 220 lbs.

EC200 Pro FAQs
Is EC200 Pro good for long workdays?
Yes. The full mesh seat promotes airflow to prevent overheating, while the adjustable lumbar support, 4D armrests, and reclining backrest work together to support you through 8+ hour workdays.
What makes the full mesh seat different?
The 100% high-elastic mesh seat allows continuous air circulation to keep you cool, while providing flexible support that maintains its shape. It's a cooler, more breathable option for long sitting sessions compared to traditional foam cushions.
Can I adjust the chair to fit my body?
Yes. The EC200 Pro offers adjustable seat depth (1.97" / 5 positions), lumbar support (2.36" height + 0.8" depth), 4D armrests, 3D headrest, chair height, recline, and tilt tension — letting you fine-tune the fit for your body.
What do the 4D armrests adjust?
The 4D armrests adjust up/down, forward/back, left/right (inward/outward), and feature 30° rotation — giving you full control to support your arms while working, typing, or relaxing.
Can I recline in this chair?
Yes. EC200 Pro locks in 4 recline positions — 90°, 105°, 120°, and 130° — so you can sit upright for work, lean back for reading or calls, or relax during short breaks.
Is it easy to assemble?
Yes. Assembly takes about 20 minutes with the included tools and visual guide. All necessary components — five-star base, armrests, tilt mechanism, seat cushion, backrest, and headrest — are included.
