About this item
- Adaptive Lumbar Support That Moves With You – Say goodbye to hollow lower back. This ergonomic office chair features a self‑adjusting lumbar that flexes as you lean forward or recline. Whether sitting upright for work or leaning back, it stays close to your spine’s curve – relieving pressure during long hours. (Lumbar width: 20cm, height from seat: 19.5cm)
- 2D Flip‑Up Armrests & Space‑Saving Design – The 2D armrests adjust up/down and flip up 70°. Recline synchronisation 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)
- 3‑Position Recline for Work, Rest, and Everything In Between – Choose from 113°, 123°, or 133° recline angles to switch between focussed work, relaxed thinking, or quick naps. The 2D headrest (11 height positions, 45° rotation) supports your neck at any angle.
- Breathable Dual‑Mesh & Heavy‑Duty Build – Headrest and back use wave mesh, seat uses polyester mesh – resisting heat and UV, keeping you dry even after 10+ hours. The SGS Class‑4 gas lift (120,000 cycles) and BIFMA‑certified steel base support .
- Fully Adjustable for All Body Types & Silent Casters – Seat height from 46.5cm to 55.5cm fits users from 5'1" to 6'1". The 6cm silent PU casters glide noise‑free on hardwood or carpet – perfect for quiet home offices. Backed by a 3‑year warranty and 30‑day returns.

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.
