Both of these brands produce mattresses. However, there is a significant difference between the two projects. For instance, Mouka foam is harder than Vitafoam. Is it good or bad? It depends. If you like harder beds, then obviously Mouka is your choice. It is a healthier one, too. As it is good for the spine to sleep on harder surfaces.
Although, you should get used to it, otherwise prepare to feel certain discomfort at first. For those who love soft beds, Vitafoam is the best choice.
