I read that the 36" platform are mainly meant for women who have height of atleast 5 feet 5".
I would recommend that you carefully consider the optimum height as many things are connected to this parameter.
For your kitchen I wouldnt recommend (36-5) inches. Perhaps 32" would be ideal. try to have a wooden board placed at this height and check with your wife if she is comfortable with this prior to execution of work.
