HydroTilt Evaluation by the Medical Devices Agency

1998 – Medical Devices Agency1:

  • The Medical Devices Agency evaluated our HydroTilt chair by measuring the ischial interface pressures of 12 elderly able-bodied subjects
  • The results of the HydroTilt were compared to the subjects’ ‘reference’ armchair
  • The HydroTilt gave among the lowest interface pressures with a mean of 64.2 mmHg, compared to the ‘reference’ armchair’s mean of over 90 mmHg



Medical Devices Agency (MDA) (1998) Evaluation: Armchairs with special features to reduce interface pressure. Alternating pressure cushions and supplementary cushions. A comparative evaluation
