SAN ANTONIO (CBSLA.com) — A Texas mattress store apologized Thursday for a 9/11-themed ad that depicted two towers of pillows being knocked over in a comical fashion.

The ad from Miracle Mattress featured three apparent store representatives offering shoppers any sized mattress for a “twin price”. Two of the actors are then seen crashing into the two pillow towers – one of which had a small American flag placed at the top – and knocking them over.

After one of the actors shrieks in terror as the pillows come crashing down, the ad – which was quickly taken down – concludes with the woman solemnly stating, “We’ll never forget.”

The store also posted ads on Twitter referencing its “Twin Tower Sale” and using the hashtags #worldtradecenter, #twintowers, and #neverforget.

Shortly after pulling the ad, Miracle Mattress issued an apology on its Facebook page, which read in part: “We are very sorry we have offended you. Our intentions were not to hurt anyone at all. Our staff is full of military and some relatives have passed away due to 9/11. … Please accept our apology.”
