Operating Instructions
Your JUMMICO JETSTREAM gaming chair offers several adjustable features for personalized comfort.
- Height Adjustment: Locate the lever on the right side beneath the seat. To raise the chair, lift the lever while taking your weight off the seat. To lower the chair, lift the lever while seated. Release the lever to lock the height.
- Backrest Recline: Use the recline lever, typically located on the left side of the seat. Pull the lever up to unlock the backrest, adjust to your desired angle (90, 120, or 150 degrees), and release the lever to lock it in place.
- Footrest Operation: The retractable footrest can be pulled out from beneath the seat when desired. Extend it fully for leg support and push it back in when not in use.
- Lumbar Massage Function: The lumbar cushion features an electric massage function. Connect the USB cable from the cushion to a compatible USB power source (e.g., computer, power bank, USB wall adapter). The massage function helps alleviate fatigue during long sessions.
- Movable Armrests: The armrests are designed to move with the recline of the backrest, providing continuous support in various positions.

Maintenance
Regular maintenance will help preserve the appearance and functionality of your JUMMICO JETSTREAM chair.
