Amazon has become embroiled in a sexism row after a trampoline listed for sale included instructions which stated that women should not attempt to install them alone.
The description on the Newan 40 inch 'mini bouncer', advertised for $176, claims that only men can assemble the fitness item as "the elastic rope part can be tricky".
The product is displayed with an image of a woman carrying out exercises in sportswear and is recommended to be used for workouts for adults and children.
It reads: "This fitness rebounder has a relatively simple installation process, but the elastic rope part can be tricky. Not advised for child or woman to install alone, additional assistance from men is preferred."
