The ROM Prone Cart provides the length necessary for a tall adult, but can
shorten its length to make maneuvering a breeze: Standard length is 72″ (adjustable
between 67″ and 77″). Shown in the video at 180° to 90°, the elevating hip
platform is adjustable to any point between those two positions. The elevating chest
platform, as shown in the last section of the video, helps eliminate fatigue and will keep you out and about
for hours. Manual propel is standard, power drive upgrade is optional. Available for Purchase or Rental.
