There are two types of beds in TFC. The regular minecraft bed and the straw & hide bed.
Straw & Hide BedsEdit
This low tier bed is constructed by placing two straw thatch adjacent to each other on the ground, and then using a large hide on the foot end of the straw bed. This bed can only be used to reset the spawn position if killed, and will not allow sleeping through the night. The large hide is dropped by cows, bears, and horses.
