HBADA has introduced the E3 Ultra (Gen 5) Ergonomic Chair, a model built around a support system designed to follow changes in sitting posture alongside adjustable lumbar support, heated massage and a reclining range of up to 150°. The chair is intended for users who alternate between desk work, gaming and relaxation throughout the day.
At the core of the design is a linked mechanism that adjusts several support components as occupants change position. According to HBADA, this system is designed to maintain contact with the body when users sit upright, lean forwards or recline, while integrated massage and heating functions provide additional comfort options during extended sitting sessions.
Mechanical support adapts to changing postures
To coordinate movement across the headrest, backrest, lumbar support, armrests and chassis, the E3 Ultra uses HBADA’s Full-Body Active Tracking System. This assembly combines a 12-rail linkage architecture, an eight-axis synchronised motion system and a three-spring damping mechanism, allowing the support structure to move with the occupant as they lean towards a laptop, sit upright during meetings or recline during breaks. HBADA designed the system to maintain support across different sitting positions without requiring users to remain in one posture.
Lower-back support is handled by the patented 3-Zone Dynamic Lumbar Support system, which employs a three-zone surround design to accommodate different body shapes and sitting positions. Adjustable lumbar wings rotate by approximately 80° to adapt to movement around the lower back, working alongside 60 mm of independent lumbar height adjustment and 32 mm of dynamic lumbar tracking movement. Aligned with the L1–L5 lumbar region, the mechanism is designed to maintain lower-back contact during both upright work and reclining.
Integrated massage and heating offer adjustable comfort
Built into the chair is HBADA’s Heated 4D Bionic Massage Core, which pairs kneading, vibration and tapping functions with graphene heating technology. Intended to provide additional comfort during longer work sessions, gaming or breaks, the system offers three massage intensity settings and three heating levels. Independent controls for each function allow massage strength and heating level to be adjusted separately according to individual preferences.
A wired controller provides one-touch operation, while the heating function supports five-minute sessions. Both functions can be used while seated, allowing users to take short breaks between meetings, coding sessions or other desk-based activities.
Reclining adjustments and seating fit
For posture changes across different tasks, the E3 Ultra offers a 150° reclining range with four locking positions, enabling users to adjust the backrest for upright work, gaming, reading or relaxation. As the backrest angle changes, 8D recline-linked armrests move with the reclining mechanism to help maintain arm and shoulder support. Additional adjustment for varied sitting positions comes from a 4D dual-axis adaptive headrest, which HBADA says accommodates users ranging from approximately 5 ft 1 in to 6 ft 3 in tall.
At the base, the seat uses pressure-distributing breathable mesh designed to improve ventilation and maintain support during prolonged sitting, paired with seat-depth adjustment so users can better match their body proportions. High-resilience mesh and a reinforced load-bearing structure complete the chair’s construction, which HBADA says is intended to accommodate a range of users, including those with larger body types.
