Hbada T8 Max Smart Ergonomic Office Chair – AI Lumbar Tracking, Ventilated Seat & Electric Footrest

The Hbada T8 Max is a smart ergonomic office chair for people who spend long days at a desk. Its AI lumbar support reads your posture and follows your lower back on its own, a keel-style backrest supports six zones of your back at once, a ventilated seat keeps you cool, and an electric footrest folds out from under the seat when you want to recline. The powered functions run from a removable rechargeable battery, so there is no cable running to your desk.

Key features

Lumbar support that follows you

Millimetre-wave radar and posture sensors in the backrest detect where your lower back is and how hard you are leaning. The lumbar support then moves to match, whether you sit upright, lean forward to type or recline to read. There is no knob to turn and nothing to remember.

Six-zone keel backrest

Three rigid spines carry ten flexible bionic panels that bend independently. As you change position the panels keep contact with your lumbar, mid-back, shoulders and neck at the same time, so no part of your back is left hanging in space during a long session.

Twenty ways to adjust

Lumbar, back and neck height move together as one unit. Seat depth adjusts to your leg length (46 cm ± 1 cm). The headrest adjusts for height, depth and tilt. The 4D armrests are linked to the backrest so they stay under your forearms as you recline, and the seat slides inward at the same time to keep you supported. The backrest reclines to 152° and locks at 105°, 115°, 125°, 135° or 152°.

Ventilated seat

A centrifugal fan and directional air guides move air through the seat and lower backrest in separate zones. Three fan speeds go up to 4,000 rpm, and the system switches itself off when you leave the chair.

Stretch and reminders

A three-level spinal stretch function gently extends your back during breaks, and a sedentary reminder prompts you to move after you have been sitting for too long.

Electric footrest

The footrest is built into the chair and stores under the seat. It extends at 6.7 mm per second at the press of a button and has passed a 100,000-cycle fatigue test.

Materials

The seat is upholstered in Gabriel Atlantic fabric from Denmark, which resists water, oil and stains while staying breathable. Underneath is a five-layer cushion of high-density zoned foam and hydrophilic memory foam that relieves pressure where you need it. The armrest pads are high-strength engineering PU, the gas lift is class 4 and the five-star base is aluminium alloy.

Battery powered

The lumbar drive, ventilation and electric footrest run from a removable rechargeable battery pack, so the chair moves freely and there is no cable to your desk.

Who this chair is for

• Full-time desk workers and home-office users who sit for six hours or more a day
• Gamers and creators who alternate between upright work and reclined breaks
• Anyone who finds a fixed lumbar support never sits in quite the right place
• Warm rooms and summer use, where a ventilated seat makes a real difference
• Users between 150 cm and 195 cm tall and up to 136 kg

Consider another option if:

• You need a light chair that is easy to carry between rooms or upstairs
• You would rather not have a chair with electronics and a battery to charge
• You want a plain mesh task chair without electronics

Frequently asked questions

Do I have to adjust the lumbar support myself?
No. The sensors in the backrest detect your posture and the lumbar support moves to match. You can still fine-tune the overall height of the lumbar, back and neck unit.

Can I turn the seat fan off?
Yes. It has two speeds and off, and it switches itself off automatically when you get up.

Does the footrest come off?
The footrest is built in. When you do not need it, it retracts fully under the seat and is out of the way.

What is the weight limit?
136 kg, as listed by Hbada. Please do not order the chair for a user above this limit.

Does it need to be plugged in?
No. The lumbar drive, fan and footrest run from a removable rechargeable battery pack. Charge it with the charger and put it back in the chair.

How far does it recline?
To 152°, with lock positions at 105°, 115°, 125°, 135° and 152°. The built-in footrest and linked armrests let you lie back for a midday rest.

Does it arrive assembled?
No. The chair ships flat-packed in one carton and is assembled at home. Allow two people.

How much is delivery?
It depends on your postcode and is shown at checkout before payment. Add the chair to your cart and enter your address to see it.

What if it arrives damaged or develops a fault?
Contact us. Under the Australian Consumer Law we repair, replace or refund depending on the failure, and we arrange and pay for the return of a faulty chair.
