Gail Berman’s Jackal Group has reunited with writer Jay Lacopo to develop a workplace comedy set in a San Fernando Valley mattress store.

“Mattress World” revolves around a failed entrepreneur who retreats to the mattress store he once managed with the goal of making it the valley’s No. 1 mattress store. Lacopo worked with Berman and Jackal Group last season on the short-lived Fox comedy “Cooper Barrett’s Guide to Surviving Life.”

Lacopo is writing the pilot and exec producing with Berman and Jackal Group’s Joe Earley.

Jackal Group is getting ready to raise the curtain on its new production of “The Rocky Horror Picture Show,” which bows Oct. 20 on Fox.

The company has TV projects in the works at Lifetime, USA Network, MTV and other nets. Jackal also has film development percolating, including “The Addams Family” at MGM and an Elvis Presley biopic at Warner Bros.

Berman’s banner signed a wide-ranging TV deal with Fox Networks Group in 2014 and a first-look agreement with Fox 2000 last year.

Lacopo is repped by WME.
