SAN ANTONIO -- A mattress store has apologized amid mounting social media criticism of a commercial advertising a 9/11 "Twin Towers" sale.

A video circulating on Facebook on Thursday shows a commercial from Miracle Mattress, which is located on Northwest Loop 410.

The commercial states: "Right now, you can get any size mattress for a twin price." It is centered around the anniversary of the September 11, 2001, terrorist attacks.

It also shows people in the commercial falling onto two stacks of mattresses, knocking them to the ground.

Facebook users are calling the ad "disgusting" and in poor taste.

Miracle Mattress posted the following statement on its Facebook page in response to the online backlash:

"To all of those who have seen our 9/11 sale. 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. We are promoters of peace and love. We have given abundantly to our community here in San Antonio and wish to remain known as a company who respects and loves others. We hope you find it in your hearts to forgive us. Please accept our apology."

The ad has since been pulled from Miracle Mattress' Facebook page. It's not clear yet whether the commercial aired on local TV stations.

This is a developing story, and will continue to post updates as they become available.
