[OPEN BOX] HBADA P1 PRO / Class 4 Gas Lift / 145° Angle Recline / 3D Wide Large Neck Pillow / Upgraded Spinal Support Large Double Back / 8xm Sponge Seat Cushion / Adjustable Headrest / OB-P102BVA

The HBADA P1 Gen 2 is a mesh office chair built around a two-piece backrest that separates upper-back and lumbar support so each moves on its own. The lumbar section tracks through 40 degrees as you shift position. It carries a 3D adjustable headrest, linked flip-up armrests and a 145-degree recline.

The Gen 2 specification covers a 3D wide neck pillow, a 145-degree recline, the upgraded double back, linked flip-up armrests, a native sponge seat and a 2.5mm thickened steel chassis. It sits on an SGS Class 4 gas lift and a nylon five-star base. Quiet casters finish it.

HBADA lists six upgrades for this generation, among them the large dual-back for spine protection, 40-degree adaptive lumbar support and the 90-degree linked flip-up armrest. The dual-back is the headline change, splitting one panel into two that move separately. The rest refine parts that already existed.

Three figures describe most of this chair: a 3D wide headrest, an 8cm sponge seat cushion and a 145-degree recline. The headrest moves in three axes rather than up and down only. The recline range is what separates a chair you work in from one you can rest back in.

The lumbar section is mounted to move with the lower back rather than sitting fixed behind it, travelling through 40 degrees. Lean forward to type or back to read and contact is kept rather than lost. This is the dynamic half of the double-back design.

Behind the mesh sits a two-layer frame carrying the load of the backrest and the recline mechanism. Reinforcing it in two layers is what allows a 145-degree recline without flex through the panel. It is the structural part you never see once the chair is built.

The backrest is both larger and more curved than the previous generation, wrapping around the sides rather than meeting the back flat. Spreading contact over a bigger area lowers the pressure at any single point. HBADA gives the back panel an area of 968 square centimetres.

The backrest is shaped to meet three regions in sequence rather than as one flat plane, following the line of the spine. The intent is continuous contact from the neck down to the waist. It is why the panel is curved in two directions instead of one.

The lowest part of the backrest is shaped to meet the sacrum, the wedge of bone at the base of the spine. HBADA calls this a bionic structure, and its job is to spread pressure across that area rather than concentrate it. It is the point most office chairs leave unsupported.

The headrest pillow measures 30cm across, wide enough to stay in contact when you turn your head rather than only when facing straight ahead. It is the part of the chair most used during a deep recline. Gen 2 enlarged it over the previous version.

The headrest travels 75mm through its height range, 40mm forward and backward, and rotates through 45 degrees. Three axes rather than one is what lets it meet different neck lengths and seated postures. Each adjustment holds where you set it.

The backrest tilts from an upright 105 degrees through 125 to a full 145 degrees, and the lock is stepless rather than notched. It holds wherever you stop instead of snapping to a preset. At 145 degrees the chair is far enough back to rest in properly.

The seat pad is 8cm of high-elasticity sponge rather than a thin foam layer over a board. Depth is what stops a seat bottoming out over a long session. HBADA cuts the pad from a single piece rather than bonding offcuts together.

The seat frame measures 2652 square centimetres, which leaves room to change position rather than sitting locked into one posture. A wider frame matters most for cross-legged and side-on sitting. The figure is measured across the frame, not the cushion alone.

The armrests are linked to the backrest, so they follow it through the recline instead of dropping away as you lean back. Elbow support is kept at every angle. They also flip up through 90 degrees when you want them out of the way entirely.

With the armrests folded through 90 degrees the chair slides fully under a desk. HBADA puts the floor space recovered at roughly one square metre. In a small room that is the difference between a clear walkway and an obstacle.

The seat sponge is a whole-piece native cut rather than bonded fragments, with no chemical adhesives holding it together. HBADA describes the material as uniform and odourless. Cutting from one piece is what stops a cushion powdering and forming hollows over time.

The height cylinder is an SGS Class 4 gas lift and the chassis is 2.5mm thickened steel, which HBADA describes as explosion-proof. Underneath sits a nylon five-star base rated at 1136kg load bearing. The casters are the quiet, floor-friendly type.

HBADA states the chair is tested according to BIFMA X5.1, the international standard covering general-purpose office chairs. That programme puts the seat, back and base through repeated load cycles. It is the usual benchmark quoted for office seating.
