Size and fit:
After the seat arrived, I realized sadly that the seat of a normal office chair is too small for the seating area of the pad (the sample sit in the shop there were TV chair, which are cut differently, as I then realized). If you so it sits down, dangling her legs from mid-thigh around freely. The do not like and is also uncomfortable in the long run. The back area is well sized and also comfortable, the neck area again is not issued, so that the massage heads to the neck can not be achieved without deliberate dislocation of the neck.
Features:
The work of massage heads is as expected great. The effect is very relaxing, so I had to give up my original plan to let me knead doing office work. I turn off so that I can not even play solitaire during the massage. ;)
The three-stage vibration in the seat is a nice feature about the meaningfulness must each decide for themselves.
Unfortunately I can not confirm the effect of heat by the infrared light. Although one sees the light through the fabric, but there is no heat radiation.
For a massage pad from the lower price segment, the Medisana RBI is pretty good, although it annoyed that the advertised heating function is not given. However, their main task they fulfilled perfectly and I give all the three stars.
