Is this a shiatsu massager or a vibration massager?

It is a vibration mat. Ten motors buzz against the muscles in five patterns and three intensities. There are no rollers, so it does not knead or press deep knots the way a shiatsu chair does.

Can I use only the neck or only the legs?

Yes. The neck, back, lumbar and leg zones can be switched on separately or combined, so you can target one area or run the whole mat.

Where does the heat apply?

The heat is in the lumbar section only. It warms the lower back while the motors run; the neck, upper back and legs get vibration without heat.

Can I use it on a bed or recliner?

Yes. It is a flexible pad meant for a bed, couch, recliner, chair or the floor, and it folds for storage between uses.

Does it need to be plugged in?

Yes. It runs from a wall outlet, so there is no battery and no cordless use.

How does it compare with a massage cushion?

A massage cushion usually gives concentrated shiatsu pressure to the back. This mat spreads gentler vibration and lumbar heat across the whole body, which suits unwinding rather than deep muscle work.
