Sia was designed around what could be taken away.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eBoss Design started by cutting the component count, then removing the adhesives entirely. Nothing on the chair is glued, which means nothing has to be prised, shredded or landfilled when the chair reaches the end of its working life. Parts unbolt, separate cleanly and go back into their own material streams. Virgin material use across the chair is down to 30% — the other 70% is recycled.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThat figure is the headline, but the details behind it matter more to a fit-out specifier. The knitted mesh back is woven from SEAQUAL® yarn, produced from 100% post-consumer recycled plastic waste collected from land and sea. It is available in 32 colour options of recycled yarn across the five mesh styles. The reduced component count lowers the sourcing footprint, where the overwhelming majority of a task chair’s cradle-to-gate carbon is generated.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch4\u003e\u003cspan\u003eErgonomics developed with FIRA\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\u003cspan\u003eSia’s adjustment range was developed working closely with ergonomist Levent Caglar at FIRA, and the numbers are genuinely generous for a chair at this level:\u003c\/span\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan\u003eSeat height: 120mm of travel\u003c\/span\u003e\u003cspan\u003e (400–510mm) — covers 5th percentile female to 95th percentile male seated postures without a footrest for most users\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eSeat depth: 80mm of adjustment\u003c\/span\u003e\u003cspan\u003e (400–480mm) — the single most-neglected adjustment on budget task seating, and the one that decides whether a shorter user gets any back support at all\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eLumbar height: 100mm of adjustment\u003c\/span\u003e\u003cspan\u003e — the lumbar pad moves to the user, not the other way round\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eBack lock: 3 positions\u003c\/span\u003e\u003cspan\u003e, plus free recline\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eWeight-balance mechanism with additional tension adjustment\u003c\/span\u003e\u003cspan\u003e — the chair self-adjusts to the user’s weight on sitting, so recline resistance is broadly right before anyone touches a dial, with a tension control for users at the extremes\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cspan\u003eThat last point is the one worth labouring in a fit-out context. Weight-balance mechanisms exist because most people never adjust their chair. In a 200-desk office, a chair that is ergonomically correct out of the box is worth more than a chair with twelve levers nobody pulls.\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Furnify","offers":[{"title":"Default Title","offer_id":53579025645904,"sku":null,"price":373.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/4984\/5584\/files\/BD-Sia-Task-Chair-P3.jpg?v=1789038185","url":"https:\/\/furnify.co.uk\/products\/boss-design-sia-task-chair","provider":"Furnify","version":"1.0","type":"link"}
