the pillow, and then repeat the operations again from the start.

clothing, and ambient temperature.

residual heat.
• The temperature you feel may rise when you massage the same area for a long time even if the "Heat" massage heads
setting is set to Off.
Reclining does not take place even though a massage is started in pre-programs.
