Query: Awful

The only customer who should go for this chair is the one which loves extensive unnecessary cleaning. The number of cracks and crevices are endless. We've started lining the plastic of the chair with saran wrap after we found a blackish mold in one undiscovered crevice.The device is impossible to keep clean. If I had to do it again, I would absolutely not buy it.
