{"product_id":"fauteuil-ergonomique-dorsaflex","title":"DorsaFlex™ Ergonomic Chair with Dynamic Support","description":"\u003cdiv class=\"product-description\"\u003e\n\u003cp\u003eYou've bought an \"ergonomic\" chair before. Adjustable, mesh-backed, delivered with a plastic lumbar support and a twelve-page manual. You spent a Sunday setting it up. Three weeks later, your back still hurt. \u003cstrong\u003eThe DorsaFlex™ is not another adjustable chair.\u003c\/strong\u003e It's a backrest that moves \u003cem\u003ewith\u003c\/em\u003e you: 8 articulated panels, motor-driven, following your spine in real time. You no longer adjust your chair — it adjusts to you.\u003c\/p\u003e\n\n\u003ch2\u003eWhy your back hurts (and why it isn't your posture)\u003c\/h2\u003e\n\u003cp\u003eYou've been told to \"sit up straight\". That's the wrong advice. Backs don't suffer from a bad position: they suffer from \u003cstrong\u003estaying still\u003c\/strong\u003e. Eight hours frozen in the same posture — even a perfect posture — and the lumbar discs compress, circulation slows, the deep muscles switch off. That's exactly why a \"well-adjusted\" chair isn't enough: a perfect position held for too long is still a position held for too long.\u003c\/p\u003e\n\u003cp\u003eThe DorsaFlex™ tackles that problem head-on. Its backrest keeps you in \u003cstrong\u003emicro-movement\u003c\/strong\u003e all day: it hollows, straightens and follows every shift in your weight, without you having to think about it. You move without noticing. By the evening, you feel the difference in your lower back.\u003c\/p\u003e\n\n\u003ch2\u003eWhat actually changes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e🦴 \u003cstrong\u003eA living backrest, not a shell:\u003c\/strong\u003e 8 flexible panels linked by 14 double articulation points and 16 ball pivots. Where a rigid shell forces its curve on your back, the DorsaFlex™ follows yours — including when you lean to one side.\u003c\/li\u003e\n\u003cli\u003e🔄 \u003cstrong\u003eEverything follows, all at once:\u003c\/strong\u003e the headrest supports your neck, the backrest tracks your spine, the seat adapts to your hips and the armrests glide 100 mm with your arms. Nothing to readjust when you shift position.\u003c\/li\u003e\n\u003cli\u003e💆 \u003cstrong\u003eA genuine back stretch in 5 minutes:\u003c\/strong\u003e DorsaStretch™ mode decompresses the spine over 50 mm of motorised travel. At 4 pm you recline, start the cycle, and get back to work without the usual band of tension across your lower back.\u003c\/li\u003e\n\u003cli\u003e🛋️ \u003cstrong\u003eFrom 105° to 160°, in 4 positions:\u003c\/strong\u003e upright for working, open for reading, almost flat for a 20-minute nap. One chair for the whole day.\u003c\/li\u003e\n\u003cli\u003e👀 \u003cstrong\u003eYour screen stays at the right height:\u003c\/strong\u003e the headrest and the backrest recline at different rates, so your eyeline stays aligned when you tip back. You relax without having to lift your head to see the screen.\u003c\/li\u003e\n\u003cli\u003e🔋 \u003cstrong\u003eA battery you forget about:\u003c\/strong\u003e 2,200 mAh.
