I've seen a few Meditationsbänkchen and tried and decided on this. First, the design for ;-) But then it also has practically convinced me. The centrally arranged stamp initially seem strangely. To comfortably sit down, you go first to their knees position and then pushes the Bänckchen under the ass.
Angle and height vote optimal recommended garden mat for your knees. Beautiful to look at and ergonomically ideal.
