About This

  • ADAPTIVE DYNAMIC LUMBAR SUPPORT — Long hours at your desk shouldn’t leave your lower back aching. The SIHOO B100 ergonomic office chair features elastic lumbar support with a dual-back design that moves with your spine. Lean forward to focus, sit upright in meetings, or shift positions throughout the day—this desk chair adapts with you, keeping your back supported and comfortable without feeling stiff.
  • RETRACTABLE FOOTREST FOR FULL RELAXATION — Pull out the smooth footrest and stretch out fully. Lean back, relax, and transform this computer chair into a personal lounge for quick power naps, gaming sessions, or movie breaks after work. Comfort follows your every move.
  • 4D ARMRESTS & LOCKABLE RECLINE — Adjust, rotate, or flip the 4D armrests to fit your posture or slide neatly under your desk. Three recline angles (110° / 125° / 135°) let this office chair shift effortlessly from focused work to relaxing breaks—perfect for home offices, gaming, or long study sessions.
  • PLUSH CUSHION & ULTRA-WIDE HEADREST — The widened seat cushion spreads weight evenly for lasting comfort. The 3D ultra-wide headrest supports your neck naturally, keeping shoulders relaxed during typing, calls, or video conferences. Sit longer, stay supported, and feel the difference in every hour at your desk.
  • BREATHABLE MESH THAT WORKS AS HARD AS YOU DO — The full-mesh back and seat promote airflow, keeping you cool through long workdays or late-night gaming. Supportive yet breathable, this mesh office chair prevents overheating and delivers consistent comfort all day.
