{"product_id":"hbada-t8-max-ergonomic-office-chair","title":"HBADA T8 Max Ergonomic Office Chair","description":"\u003cp\u003eThe HBADA T8 Max is a smart ergonomic chair built around lumbar support that actively follows you. Sensors read your posture in real time and an electric push-rod keeps the lumbar support against your lower back as you lean forward, sit upright or recline, with no manual adjusting. Around it, HBADA’s whole-chair follow-motion architecture moves the backrest, seat and armrests together, a keel-frame back flexes to your spine, and a ventilated seat keeps you cool.\u003c\/p\u003e\n\u003cp\u003eUp to 20 adjustments fit people from 150 to 195 cm tall and up to 136 kg. The T8 Max comes in White and Black (HBADA calls them Mist White and Mountain Black). Sit-test it at our Sydney or Melbourne showroom.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSmart lumbar tracking with real-time posture sensing and an electric push-rod\u003c\/li\u003e\n\u003cli\u003eWhole-chair follow-motion: a 12-track, 8-axis, 3-spring linkage\u003c\/li\u003e\n\u003cli\u003eKeel-frame back with 3 keel supports, 10 bionic flexible panels and 18 flexible dual-link joints\u003c\/li\u003e\n\u003cli\u003ePressure spread across six zones, from neck to thighs\u003c\/li\u003e\n\u003cli\u003eVentilated seat with three fan levels and leave-seat sensing\u003c\/li\u003e\n\u003cli\u003e4D dual-axis headrest, 4D linked armrests, a 470 mm pull-out footrest and five recline positions from 105° to 152°\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSmart lumbar tracking\u003c\/h2\u003e\n\u003cp\u003eOn the T8 Max, sensors in the lumbar area and seat read your posture, a chip calculates the support position and force, and a motor-driven push-rod moves the support with millimetre precision. Because it pushes straight in rather than at an angle, HBADA says support lands where your lower back needs it, with no gap at the sacrum. HBADA quotes a 6.7 mm\/s response, a 22° support angle, 100,000-cycle fatigue testing and around 50 dB in operation.\u003c\/p\u003e\n\u003cp\u003eTracking works whether you are leaning forward, sitting upright, sitting back or reclining. Hold the AI button on the armrest for four seconds to start it; two more buttons move the support forward or back by hand. A one-touch spine stretch with three levels works upright or reclined, and the chair adds an automatic sitting reminder.\u003c\/p\u003e\n\n\u003ch2\u003eWhole-chair follow-motion\u003c\/h2\u003e\n\u003cp\u003eHBADA’s all-scenario dynamic support system links the backrest, seat and armrests through its own 12-track, 8-axis, 3-spring architecture. The backrest stays against your back, the seat moves with your hips so your shirt doesn’t pull as you recline, and the 4D linked armrests keep your arms supported.\u003c\/p\u003e\n\u003cp\u003eThe back is a keel frame: three stable keel supports, ten bionic flexible panels and 18 flexible dual-link joints. It flexes to follow the curve of your spine without sagging, and a precision-controlled motor draws the flexible backrest into shape to suit different spinal curves.\u003c\/p\u003e\n\u003cp\u003eHBADA’s Pascal full-surface pressure-distribution system balances contact area against support force, spreading pressure that would otherwise sit on the lower back across six zones: neck, shoulders, elbows, lower back, hips and thighs. It is designed to reduce lumbar pressure over long sitting sessions.\u003c\/p\u003e\n\n\u003ch2\u003eComfort and ventilation\u003c\/h2\u003e\n\u003cp\u003eThe foam is zoned by job: skin-soft memory foam in the headrest, high-density elastic foam in the backrest, soft resilient foam on the armrests, and a seat cushion with three firmness zones from front to back for the hips and thighs. The breathable seat fabric has a water-, oil- and stain-resistant finish.\u003c\/p\u003e\n\u003cp\u003eThe smart ventilation system pulls air through five layers (breathable fabric, 3D breathable mesh, perforated foam, 3D airflow mesh and a directional air guide) using a centrifugal fan rated at 4,200 rpm. Three fan levels, Breeze, Cool and Fresh, run for up to 33, 16 and 7 hours per charge from the 2600 mAh battery box. Leave-seat sensing stops the fan when you stand up and restarts it when you sit back down.\u003c\/p\u003e\n\n\u003ch2\u003eAdjustability\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack, lumbar and headrest:\u003c\/strong\u003e one-piece height adjustment of 50 mm, so the back, lumbar support and headrest move together\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadrest:\u003c\/strong\u003e 4D dual-axis, rotating up to 70° on two axes, with a memory-foam pad\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArmrests:\u003c\/strong\u003e 4D linked armrests that move with the chair; armrest height 64–80 cm from the floor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat depth:\u003c\/strong\u003e 36.5–49 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat height:\u003c\/strong\u003e 45–53 cm on a Class 4 gas lift\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecline:\u003c\/strong\u003e five positions: 105° Focus, 115° Deep Work, 125° Ideas, 135° Break and 152° Recharge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFootrest:\u003c\/strong\u003e padded 470 mm pull-out footrest that moves with the chair and tucks away under the seat\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTo set up, adjust the seat height so your feet sit flat, leave a small gap behind your knees, raise the back unit until the lumbar support meets your lower back, then start lumbar tracking and set the armrests and headrest.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eHBADA T8 Max\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eColours\u003c\/td\u003e\n\u003ctd\u003eWhite, Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended user height\u003c\/td\u003e\n\u003ctd\u003e150–195 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum load\u003c\/td\u003e\n\u003ctd\u003e136 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall height\u003c\/td\u003e\n\u003ctd\u003e112–124 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall width (across armrests)\u003c\/td\u003e\n\u003ctd\u003e65.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase diameter\u003c\/td\u003e\n\u003ctd\u003e70 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeat height\u003c\/td\u003e\n\u003ctd\u003e45–53 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeat width\u003c\/td\u003e\n\u003ctd\u003e54 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeat depth\u003c\/td\u003e\n\u003ctd\u003e36.5–49 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackrest width\u003c\/td\u003e\n\u003ctd\u003e43 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeadrest width\u003c\/td\u003e\n\u003ctd\u003e33.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eArmrest height from floor\u003c\/td\u003e\n\u003ctd\u003e64–80 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecline\u003c\/td\u003e\n\u003ctd\u003e5 positions: 105°, 115°, 125°, 135°, 152°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFootrest\u003c\/td\u003e\n\u003ctd\u003e470 mm pull-out, padded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e2600 mAh battery box; 5 V \/ 2 A charging input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase and castors\u003c\/td\u003e\n\u003ctd\u003eAluminium alloy five-star base, dual quiet castors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas lift\u003c\/td\u003e\n\u003ctd\u003eClass 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTesting\u003c\/td\u003e\n\u003ctd\u003eBIFMA X5.1 (complete chair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage size\u003c\/td\u003e\n\u003ctd\u003e765 × 725 × 920 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross weight\u003c\/td\u003e\n\u003ctd\u003e33.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eDimensions are measured by hand, so allow 1–2 cm.
