Each inmate is assigned their own 7-by-12 foot cell, where they spend roughly 23 hours alone each day. The cells (and everything in them, including the sink-toilet, shower, desk, and bed) are forged from concrete. It's reportedly soundproof; that way, prisoners can't communicate with others in their block by talking or tapping out codes. A slot in the door allows for meal delivery with little to no interaction between inmates and guards. Psychiatric evaluations, spiritual guidance, and other services are also provided through the door, or via telecommunication. A 2014 Amnesty International report on the facility found "that prisoners routinely go days with only a few words spoken to them." The report was titled "Entombed—Isolation in the U.S. Prison System."
