Most massage treatments will relax you, among other things. With a relaxation massage, relaxing you is the only aim. For this reason, it is one of the most complete and indulgent massages you can have.
Definitions vary, but this is how we practice the art of relaxation massage. It is a full-body treatment involving soft music, soft lighting and creams or oils. You will have a long, luxurious massage which will use all kinds of techniques including long strokes, gentle kneading and rolling of skin and muscle, and perhaps some rhythmic rocking from side to side. It is a passive treatment. You won't be stretched or maneuvered into any yoga-like positions, as you are, for example, in Thai massage. You just lie there and enjoy it.
This is the massage to choose if you just want to chill out, and be pampered and spoiled.
