LiberNovo Dynamic Ergonomic Desk Chair + StepSync Footrest Bundle (Midnight Black, 48cm)

What height range is this chair suitable for?

This chair works best for people between 157cm and 191cm tall. The 48cm seat depth option is recommended for people over 175cm, whilst the 45cm depth suits shorter users. The headrest extends fully to accommodate taller users, though people over 191cm may find the headrest positioning less optimal. The chair's adaptive design ensures proper support across this height range.

How does the motorised lumbar support actually work?

The ErgoPulse Motor System uses 8 flexible panels that automatically adjust to create your spine's natural S-curve. The system responds to your movements in real-time, providing consistent lower back support whether you're sitting upright or reclining. The motor operates silently and draws power from the built-in battery, requiring no external power source during use.

What is the spine stretching feature and how often should I use it?

The spine stretching function gently decompresses your vertebrae by creating controlled movement in the backrest. This helps relieve pressure on spinal discs and relaxes tight back muscles. You can use this feature whenever you feel tension or stiffness, typically every 1-2 hours during long work sessions. The gentle stretching motion is safe for regular use throughout the day.

How long does the battery last and how do I charge it?

The 2200mAh battery lasts up to 30 days with daily use of the motorised features, or up to one year if you use adjustments minimally. The chair comes with a charging cable that connects to the battery compartment. A full charge takes approximately 3-4 hours and the battery indicator shows remaining power levels to help you plan charging sessions.

Can I use this chair without the footrest?

Yes, the chair functions perfectly without the footrest, though the bundle includes it for enhanced comfort. The footrest helps maintain proper leg positioning, especially when the chair is raised to match your desk height. Without it, ensure your feet can rest flat on the floor or use an alternative footrest. The chair's ergonomic benefits remain fully functional either way.

Is the chair difficult to assemble?

Assembly typically takes 15-20 minutes using the included instructions and tools. The main components connect with clear labelling and straightforward connections. The most complex part involves connecting the battery and motor system, but this follows simple plug-and-play connections. Most users can complete assembly without additional tools or technical expertise.

What weight limit does this chair support?

The chair supports up to 136kg (300lbs) safely. This weight limit applies to all functions including the recline positions and motorised adjustments. The aerospace-grade frame materials and reinforced base provide stable support across this weight range. Exceeding this limit may compromise the chair's adjustability mechanisms and void the warranty.

How do the armrests move and can I adjust them manually?

The 4D armrests adjust in height, width, depth and angle to match your arm positioning. They automatically slide back 100mm when you recline to maintain proper keyboard and mouse positioning. You can also manually adjust them for different tasks or body positions. Some users note the armrests feel slightly loose, allowing natural movement but potentially feeling less rigid than fixed armrests.
