Positional Therapy Aids For those who wish to try positional therapy first, what do you recommend as a universal entry-level model? Which product is the all-rounder for people of all weights and heights? I am looking for a positional therapy aid to prevent my sleep apnoea – what do you recommend? What can be done if, after only a few weeks, the Velcro fasteners of the Nachtwaechter Vest are no longer sticking? I’m experiencing pains in the lumbar area from wearing the Nachtwaechter. It feels as though I’m being rolled over onto my stomach. Can I test the effects of positional prevention aids, such as the Nachtwaechter vest, RLV vest, or SomnoCushion, and return them should I not be completely satisfied? Can anti-snoring pillows be tested, and returned if one is not satisfied? The inflatable air cushion of my SomnoCushion does not inflate. Is there a specific trick to aid with this process or is the cushion simply defective?
