Since 2006 the Back App chair has been on the market as a training apparatus exercising the back supporting muscles during seating. After selling 11000 chairs we sent a questionnaire to specialists (physiotherapists, chiropractors, etc) in the Nordic countries who use Back App.

The company Prognett AS arranged the independent study and received replies from 51% of the specialists (364 answered, 144 from Norway, 104 from Sweden, 60 from Denmark and 56 from Finland).

Back App can be recommended
We asked the specialists if they would advise their patients to use Back App?
348 of 364 said “Yes”
The 18 saying no had these reasons: 5 of them had no patients and could of course not advise the Back App to anybody, 6 said they thought it was too expensive, 7 said that they would not recommend the chair because of the need for height adjustable tables and because Back App was not movable (needed wheels)

Comfort
351 of 364 said that Back App seating was comfortable. Comfortable seating is a key factor for continuous use of Back App as a training apparatus.

From this extensive study we can conclude that specialists from Norway, Sweden, Denmark and Finland agree that the Back App chair is doing the job it was planned to do; Back App exercises the back supporting muscles - by sitting
