Osaki OS-4000T

When you first sit down and start a program, the chair's sensors detect your height and the specific curvature of your spine. This mapping process ensures the rollers align perfectly with your back, preventing the massage from hitting the wrong spots.

The S-Track is designed to follow the natural, ergonomic curve of your human spine. This allows the rollers to maintain consistent contact from your neck down to your lower back, providing a more uniform and effective massage than chairs with a flat track.

Yes, the OS-4000T features five different intensity levels. You can easily adjust the pressure of the rollers and the air compression to suit your comfort level at any point during your session.

Zero-gravity positioning reclines the chair to a specific angle that elevates your legs above your heart. This position helps distribute your body weight evenly across the chair, which significantly reduces spinal pressure and allows the rollers to work more deeply into your muscles.

The chair measures 52 inches wide, 31 inches deep, and 34 inches high. Keep in mind that you will need additional clearance behind the chair to allow for the full recline function, so plan for a footprint slightly larger than the chair's base dimensions.

The chair includes integrated foot rollers that provide a kneading, reflexology-style massage. This works in tandem with the air compression bags to target both the soles of your feet and the surrounding muscles.
