Back pain gone in 2 weeks
Struggled with lower back pain for years. This chair fixed it. The 4D lumbar adjusts exactly where I need it. Assembly took 20 mins and delivery was next day. Cannot recommend enough.
*****
WFH game-changer
I work 10 hours a day from home. Tried 3 other chairs before this. The seat depth slider alone makes it worth it -- finally no numb legs after lunch. Mesh is genuinely breathable too.
*****
Premium feel, genuine quality
The build quality is exceptional. Feels solid without being heavy. The recline tension is perfect. Only minor note -- took me 30 mins to assemble, not 20. But absolutely worth it.
Got questions?
Everything you need to know.
What is the maximum weight this chair supports?
-
The ET Spinal is certified to support up to 150 kg. The KGS class 4 gas lift and reinforced nylon frame are tested to twice that load for safety compliance.
How long does assembly take?
+
Most customers complete assembly in 15-20 minutes using only the included Allen key. The manual has QR codes linking to step-by-step video guides. Or choose our white-glove assembly service at checkout -- our team sets it up for you.
What does the 5-year warranty cover?
+
The full warranty covers all mechanical parts -- gas lift, lumbar mechanism, armrest joints, recliner, and the frame. It does not cover normal wear on the mesh fabric or cosmetic damage from misuse.
Can I return the chair if it doesn't suit me?
+
Yes. We offer a 30-day no-questions return policy. Contact our support team, and we arrange pickup from your address at no charge. Refund is processed within 5-7 business days.
Is this chair suitable for people under 5'2" or over 6'?
+
Yes. The seat height adjusts from 42cm to 52cm, covering heights from roughly 4'10" to 6'4". The seat depth slider adds a further 6cm of adjustment to ensure your knees sit at 90 degrees regardless of leg length.
How do I adjust the lumbar support?
+
The 4D Pivot Lumbar moves in all directions with gentle hand pressure -- no knobs or levers. Simply push it to the position that supports the curve of your lower back. It holds position and follows subtle movement throughout your day.
