Spiderman animated Wikia

Madame Web's chair was a life support system.


The longer that Madame Web spent on Earth and not in her home dimension the weaker she became. Because of this Madame Web had a chair with technology that kept her alive.

Madame Web once let Beyonder use the seat when he began to feel weak.

In the comics

In the comics the chair was built by Madame Web's husband, Jonathan Webb.
