The Atlanta Business Chronicle has also reported the suit.
An attorney for Alexander Deitch, the former senior vice president, told Bisnow that his client denied the charges. The attorney said that he expected the two other executives to deny the charges as well.
Deitch no longer works for the company, according to an email to the AJC from Jodi Selvey, a senior vice president with Colliers.
The suit was filed in a filed in Texas court last month.
The charges revolve around an alleged arrangement in which many properties were owned by a small group of developers who received inflated rents from Mattress Firm and then paid kickbacks to Colliers, Levy and Vinson.
Mattress Firm has not named a dollar figure for the damages it believes it sustained and wishes in compensation, but the suit mentions payments amounting to more than $40 million beyond the true market value of the properties, Bisnow reported.
The web site said Levy and Vinson were fired last year as an inquiry into the deals began.
