Grab your cell phone and take an office selfie for a chance to win a cool stool from OFM. OFM is looking for the best group selfie in workplace setting.

To enter, take a co-worker “selfie”, then upload the photo to Twitter or Instagram using the hashtag #OFMOfficeSelfie. Winners will be selected in three categories: best selfie with the most people, most creative and best overall. Each category winner will have the option of selecting three stools from OFM’s Jupiter, Hex or Quin series, offering a versatile seating option for any workspace.

Be sure to enter before May 31st for a chance to win. According to a Pew Research Center estimate, some 55 percent of Millennials (ages 18 to 33) have shared a selfie on social media.

Taking a selfie, especially at the office, used to be much harder, but thanks to cellphones readily found in any workplace, it’s become an everyday experience. OFM hopes to capture this phenomenon and find the best group selfie taken in a workplace setting.
