That's more staff than the company has hired in each of the last three holiday seasons and effectively doubles the company's domestic workforce, Toys R Us said in a statement.
Of the new hires, about 35,000 will staff the company's 587 traditional Toys R Us stores, with the rest working in express stores and distribution centers.
Earlier this month, Toys R Us said it plans to open more than 600 new express stores to boost the company's holiday sales.
"We're not projecting a dramatic increase in the [economic] environment. We're saying Christmas will come," said CEO Jerry Storch. "What I need to do is make sure we're stocked up with the right product for Christmas . . . if that's being optimistic, great."
