It was me that posted that I was going to get a beanbag to sit on for performing pedi's.
In the post I was specifically referring to doing pedi's on a mobile basis. When performing a mobile service we all use equipment that we would not use in the salon, eg folding camping tables as nail tables, and my point about the beanbag is that it is lightweight therefore easy to haul around from house to house, it provides a low seating position, and it is comfortable. Of course there are other options eg footstools, but this was just one option that I thought of, being that the thread was asking for suggestions and this was just mine.
I dont believe that this would look unprofessional for use at a mobile service any less than it would look unprofessional to use a camping table as a nail station at a mobile appointment.
