In 2017, the Elimination Chamber event returned (2017's event was SmackDown-exclusive while 2018's was Raw-exclusive). In addition, the chamber structure was redesigned, becoming square instead of circular. The pods were also changed from circular to square and feature sliding doors that referees slide open from outside the chamber. At the top of the chamber at its center which is now tall is a large cutout of the WWE logo. The steel grates between the ring and the cage were also replaced with padding. LED lights also line the corners of the structure. The redesign was for practical purposes due to certain venues only being able to house the previous structure, allowing most venues to host the Chamber.
