TNT's Harder Beds

Beds can only be slept in once a valid bedroom has been built around them, so a player cannot carry a bed around and set it down when the sun starts to set, and cannot dig a hole and call it a shelter. A bedroom needs walls, ceiling and floor made of full blocks; non-full functional blocks such as chests, torches and furnaces are ignored when checking it. A default block counts as valid, and the requirement can be turned off with the requireHouse setting in the config file.

The crafting recipe is changed as well. Each bed needs two mattresses, and each mattress is crafted from nine wool blocks of the same color. Mattresses combine with one block of wool of that color and three planks to form the bed, and the bed takes the color of its mattresses. Sheep drop wool only when sheared, and beds drop as items only when broken with a silk touch tool.

The mod is published for Fabric and Forge across eight release versions, 1.20.1 – 1.21.1, under the MIT License, and the code is not open source. It is a client and server mod, so the server and every player need it. Installs need a data folder named tnts harder beds, where the config file lives. The mod is most likely incompatible with other mods that change how beds function or alter their recipes, so the authors recommend playing without them.
