    Amy Maplethorpe, a first-year speech-language teacher at Raymond Ellis Primary School, used tennis balls, a hot glue gun, Mod Podge and a bit of paint to create two chairs that help students with sensory (感官的) problems.

    According to the school's Facebook page, which became very popular, the chairs provide a “different texture (质地) to improve sensory regulation (调控).”

    Maplethorpe told ABC News that the chairs will service about 15 to 20 students. Children with sensory problems often have a hard time “dealing with sensory information”. Things, such as coats, blankets and Maplethorpe's chairs, often comfort a student.

    Maplethorpe was excited to create the chair after seeing something similar on a website, and she made some changes to the idea.

    “I wanted to continue to help students with sensory problems at Ellis and provide a different kind of seat for the students,” she continued. “I was excited that this chair could help my students.''

    The two chairs are now in the school's sensory room, which was created recently, according to headmaster, Beth Kiewicz.

    “When a child's sensory needs are met, we then can move on to their needs in study,” Kiewicz, who has led the school for six years, told ABC News.

    Maplethorpe said the chairs have already made a difference for some of her students.

    “Students have become more patient, and have followed directions, while waiting for activities,” she said.
