All 156 Mattress Firm stores in Houston are hosting a School Supply Drive to benefit local foster youth and families. Through Sunday, August 27 during normal store hours, Mattress Firm will accept school supplies and monetary contributions to help give local foster children the tools they need to succeed as a new school year begins. All items collected will be donated to Angel Reach, Child Advocates, Inc., DePelchin Children’s Center and Arrow Child & Family Ministries at the end of the eight-week drive.
