Minecraft wiki entry for Combat, associated text: Put enemies to bed and lay them to rest. If the player happen to be fighting in the Nether or the End and are about to die, one of the most cruel and ironic ways to kill the enemies is to take them down with the player as they die by using a bed. Simply equip the bed, place it, click on it and it will instantly explode, killing just about anything within a 5 to 7 block radius. In terms of blast force, the bed is actually more powerful than TNT, which makes it that much deadlier and harder to survive. One major downside is that the player have to click on the bed to detonate it which means they will have to be very close to it in order to do it and since the detonation is instant, players are very likely going to kill the player when using a bed as a weapon in the Nether. As a result, aside from taking on the role of a crazy suicide bomber or tricking the opponents into accidentally detonating the bed for the player, they're better off using the bed as a last-ditch final attack to take an opponent with the player into death. However, if you place a block between you and the bed, then click on it, the bed will do little damage to you.
