About this item
- 4D Adaptive Dynamic Lumbar Support – Say goodbye to hollow lower back feeling. This ergonomic office chair features an advanced 4D adaptive lumbar system that automatically adjusts support intensity and angle as you move. Whether sitting upright for work or leaning back, it stays close to your spine’s curve – relieving pressure from prolonged sitting. (Lumbar width: 20cm, height from seat: 19.5cm)
- Multi‑Dimensional 4D Flip‑Up Armrests & Space‑Saving Design – The 4D armrests adjust forward/backward (4.5cm), rotate 360°, and flip up 70°. Recline synchronization keeps your arms supported at any angle. Flip them up to slide the chair completely under your desk – freeing up valuable office space. (Armrest size: 25.5cm L x 8.5cm W, PVC padding)
- Hidden Footrest + 3‑Position Recline for Work, Rest, and Everything In Between – Choose from 113°, 123°, or 133° recline angles to switch between focused work, relaxed thinking, or quick naps. Need to fully unwind? Pull out the hidden footrest (27cm travel, 145° rotation, max extension 44cm), kick your feet up, and melt the day away – perfect for power naps at the office.
- 3D Extra Wide Headrest & Breathable Wave Mesh – The oversized 3D headrest (36.5cm L x 17.5cm W) supports users from 5'1" to 6'1" with 11 height positions and 45° rotation. Full mesh back and seat resist heat and UV, keeping you dry and cool even after 10+ hours – no more sweaty shirts.
- Quality & After‑Sales Dual Guarantee – Built to last: SGS Class‑4 gas lift (120,000 cycles), BIFMA‑certified steel base, 350 steel base (1,136kg static test), and 6cm silent PU casters. Supports up to 120kg / 265 lbs. Backed by a 3‑year worry‑free warranty and 30‑day hassle‑free returns – enjoy complete peace of mind.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
