Create a 15-second native 9:16 vertical selfie-style UGC review of a black mesh ergonomic office chair in a bright, believable home-office corner with soft natural window light, a simple desk, laptop, and minimal everyday objects. The entire video must remain portrait 9:16 and be composed specifically for mobile viewing, with no landscape crop, letterboxing, or squeezed widescreen composition. Use realistic skin texture, mild natural phone-camera movement, casual framing, and an authentic “showing a friend my new desk chair” feeling. Use @Image1 as the absolute visual product reference for the chair. Use @Image2 as the presenter’s identity reference: preserve his recognizable face, short tousled black hair, age range, skin tone, body proportions, black overshirt, white T-shirt, dark blue jeans, and white sneakers consistently across every shot. Preserve the @Image1 chair exactly in every shot: one black ergonomic office chair with a separate wide curved black mesh headrest, a tall black mesh backrest with a gently contoured outline, a visible dark structural support behind the mesh, two black armrests with broad rectangular pads, a thick rounded black mesh seat with a slightly raised front edge, a black under-seat mechanism with the source-visible controls, a short exposed silver center column, a polished silver five-star base, and five black twin-wheel casters. Keep the headrest shape, mesh weave and transparency, backrest outline, rear support geometry, armrest positions, seat thickness, black-and-silver color scheme, central column, five base legs, and all five casters consistent. Do not invent a logo, footrest, leg rest, speakers, massage functions, RGB lights, cup holder, tray, extra padding, extra controls, different upholstery, or a different base. Do not demonstrate or claim height adjustment, reclining, tilt locking, lumbar adjustment, headrest adjustment, armrest adjustment, weight capacity, certified ergonomics, pain relief, posture correction, or medical benefits because those functions and specifications are not established by the single reference image. 0-4 seconds — vertical front-camera medium shot in the home office. Keep the complete @Image1 chair prominently visible beside the @Image2 presenter without cropping the headrest, seat, armrests, base, or casters. He looks directly into the lens, gestures toward the chair, and says naturally: “Okay, I finally replaced my desk chair, and this already feels like an upgrade.” 4-7 seconds — hard cut to a vertical handheld product close-up. Move slowly from the separate curved mesh headrest down across the transparent mesh backrest, visible rear support, broad armrest pads, and rounded mesh seat. His hand lightly presses the back mesh once and releases it, creating only subtle believable fabric flex before it returns to shape. Keep the complete chair identity readable and do not touch or operate any under-seat controls. He says: “The mesh back feels airy, and I love the shape.” 7-12 seconds — hard cut to a propped-phone vertical full-body use demonstration from a front three-quarter angle. The chair remains stationary on a flat floor. He walks in, turns naturally, and sits down once with believable weight and contact. He places both feet flat on the floor, rests his forearms naturally on the two armrest pads, leans his upper back gently into the fixed mesh backrest, and briefly rests the back of his head against the separate headrest. The mesh and seat compress subtly under contact while the chair structure, base, center column, and casters remain stable. No dialogue during this comfort demonstration; do not show powered movement, automatic reshaping, an exaggerated recline, or any unverified adjustment. 12-15 seconds — hard cut to a close vertical front-camera composition while he remains seated correctly at the desk. Keep his face, the separate headrest, mesh backrest, and both armrests clearly visible. He looks into the lens, gives a small approving nod, and says: “Yeah, this is staying at my desk.” Hold the final portrait frame steady on him seated in the source-faithful chair. Keep all dialogue verbatim and in this exact order, with natural conversational English delivery, realistic pauses, synchronized mouth movement, and gestures aligned to each line. Use clear creator speech, subtle home-office room tone, one soft mesh press sound, quiet clothing movement, and a restrained chair-and-floor contact sound as he sits. No music, voice-over, captions, subtitles, interface overlays, borders, watermarks, prices, specifications, medical claims, pain-relief claims, posture guarantees, productivity claims, durability claims, weight-capacity claims, assembly claims, or call to action. Use only purposeful hard cuts; no morphing, whip pans, speed ramps, crash zooms, camera orbits, glossy commercial moves, automatic chair transformations, duplicated furniture, or moving components not physically operated. Maintain native 9:16 framing, stable @Image2 identity, accurate hands and seated anatomy, one consistent source-faithful @Image1 chair, realistic body-to-chair contact, all five base legs and casters when visible, and clear product visibility through the final frame.
