An assistive apparatus with a buttock-spreading mechanism suitable for assisting a person in getting onto a toilet is disclosed. The person using the toilet together with the assistive apparatus is able to transfer the bodyweight of the person to be supported by the assistive apparatus, thereby avoiding the transfer or distribution of the person's heavy weight directly to the toilet itself. The buttock-spreading mechanism includes expandable leaflets disposed on a platform to comfortably accommodates the dimensions of the person's buttocks, and the leaflets of the buttock-spreading mechanism is designed to be movable (e.g., expanded or retracted) for spreading the buttocks of the person.
