Product Details & Specifications

Usage & Application Guide

Position the massage chair on a flat surface, ensuring at least 2 inches of clearance behind the backrest for full recline movement. Plug the power cable into a dedicated wall outlet and turn on the main power switch at the base. Sit back comfortably and place your forearms into the armrest slots to allow the smart Ache Sensor to detect muscle tension points. Use the LED remote control to select one of the 6 automatic massage programs or adjust manual settings, such as 2-stage Zero Gravity recline, lumbar heating, and Bluetooth audio pairing. To clean, wipe down the synthetic leather surfaces with a damp, soft cloth and mild upholstery cleaner.

FAQ

Q: How does the Ache Sensor on the Osaki OS-4000XT work?

A: Once you place your forearms naturally into the armrest sensors, the Ache Sensor measures body feedback and tension signals to pinpoint muscle tightness, customizing the massage routine to focus on those target areas.

Q: How much wall clearance is needed to recline the Osaki OS-4000XT?

A: The chair utilizes space-saving recline technology, requiring only 2 inches (5 cm) of wall clearance behind the backrest when fully reclined into Zero Gravity.

Q: What is the difference between an L-Track and standard massage rollers?

A: A standard S-Track stops at the lower back, whereas an extended L-Track follows the natural curve of your spine and extends further down underneath the seat to massage your glutes and upper hamstrings.
