The cost is good, the size and weight are also moderate.
I'm afraid that's because I'm sensitive, A slight difference in height between the treated patterned part as if the air tube had been fitted in front of the part immediately next to it. Yes, that's the feeling of slicing on your back. If you put the wind into bread, the height difference will be greater, and if you put the wind weakly, the volume difference will decrease. It's less to cut down, but the body turns off and the rustling sound becomes worse. If you put it in the wind bread, the sound is not so much.
I'm thinking about putting the wind in bread and putting something more thick on it so that the surface is less cut. In addition, to do this, the volume of the load has increased, so the original self-confidence mat was used or there is no big difference.
I feel the difference in height between volumes as much as thin pads.
