Developers and government officials are preparing to welcome the nation's largest mattress company, Serta Simmons Bedding, to move its headquarters to the site of a torn-down General Motors plant in Doraville.

Serta Simmons would bring 500 jobs, a four-story office building, a parking deck and a research facility to the site, now known as Assembly.

Serta Simmons is the first major business to locate on the 165-acre property, boosting hopes for redeveloping an area that hasn't been used since 2008, when GM's last minivans were manufactured.

The company said the deal hasn't been finalized, but the Doraville Development Authority awarded $16.8 million in potential tax incentives to Serta Simmons earlier this month, according to documents obtained by The Atlanta Journal-Constitution through a Georgia Open Records Act request.
