THE X7 INTELLIGENCE
Your posture never stays still. Your support shouldn’t either.
Throughout the day, you lean forward, sit upright, shift positions, and recline. Traditional lumbar support stays fixed. X7 actively responds as your posture changes.
Sense. Process. Adapt. Before you notice the change.

Not just support.
An intelligent comfort and recovery system.
Active Cooling
Dual 3,000 RPM fans with three airflow levels.
Lumbar Heating
Three levels of targeted warmth around the lower back.
One chair. Every way you sit.
Adjust the chair around your body—not your body around the chair.
Adjustments that fit you, head to feet.
Five adjustment points let you shape the chair around your exact body.
Slides up, tilts, and moves in and out to meet the curve of your neck — so your head feels held, not propped.
Turn, slide, and lift them to wherever your arms land. When the chair carries your arms, your shoulders relax.
Slide the seat to leave a small gap behind your knees — enough support for your thighs, no pressure on your legs.
Set it so your feet sit flat and your knees line up with your hips. Your weight rests on the chair, not your lower back.
Pull it out to recline and put your legs up between tasks, then slide it away to get back to work.

One flagship. Two ownership choices.
Same intelligence. Same ergonomic performance. Different finish, price and ownership benefits.
THE ELEVATED CHOICE
X7 Black
Premium black finish | Free gift box | +1 Year warranty extension
X7 Prestige
Rare by design. Refined without compromise.
Independent side wings on the 8-way lumbar support. Each wing rotates inward up to 40°, closing along the lumbar line to wrap the lower back regardless of body shape.
Alcantara® microfibre suede on the side bolsters and footrest. Originally developed for high-performance car interiors — breathable, abrasion-resistant, and tactile in a way no synthetic replicates.
Backspine and five-star base machined and anodised in a single process — so the tone holds consistent from every angle. Not painted. Not wrapped.
Limited production. Available by pre-order only.

Frequently asked questions
The HBADA X7 Series is a range of ergonomic office chairs with smart lumbar support that responds as you move. Instead of staying in one fixed position, the support follows you when you lean forward, sit upright or recline. The range includes the X7 Air, X7 Grey, X7 Black and X7 Prestige.
Sensors detect changes in the position of your lower back, and the lumbar support moves forward or backward to stay in contact with it. You can choose from 10 response levels depending on how closely you want it to follow you. The system offers 50 mm of powered front-to-back movement, 45 mm of manual height adjustment and 10° of adaptive movement.
X7 Grey and X7 Black have the same smart functions and ergonomic adjustments. The differences are the color, price and included benefits. X7 Grey is the standard option. Under the offer currently shown on this page, X7 Black comes with a gift box and an extra year of warranty coverage.
Yes. The X7 includes 8D bionic massage, three warmth settings for the lower-back area and an actively cooled seat. Two built-in 3,000 RPM fans provide three airflow levels. These features are intended to make work breaks and reclined rest more comfortable; they are not medical treatments.
You can adjust the lumbar response, headrest, armrests, seat depth and seat height. The 4D dual-axis headrest moves to meet your neck, while the 720° armrests support different typing, device-use and reclining positions. The chair can also be set at 105°, 116°, 128° or 140°. A footrest is included with selected configurations.
The X7 is designed for people who spend extended periods at a desk. Its moving lumbar support, adjustable armrests, breathable seat and different recline settings make it easier to change position throughout the day. Even with a supportive chair, it is still important to stand up, move around and take regular breaks.
Yes. The testing information shown on this page lists 600,000 armrest cycles, 120,000 gas-lift cycles, 120,000 rotation cycles and 100,000 recline cycles. The chair is also tested to the BIFMA X5.1 standard. How long a chair lasts in everyday use will depend on factors such as user weight, frequency of use, maintenance and environment.
The standard package shown on this page includes a 30-day home trial, a three-year warranty, free shipping and lifetime customer support. X7 Black and selected X7 Prestige offers may include an additional year of warranty coverage. Check the product page and HBADA warranty policy for the latest terms and exclusions.
