Currently, there is only a sleeping bag. It would make more sense to introduce a bed that reduces the respawn cooldown. Additionally, there could be a double bed that requires significantly more resources to craft, such as metal and nails. Besides the shorter cooldown, it would allow players to respawn at the same bed twice in a row.
This would be a particularly useful improvement during raids, as it currently takes far too long to respawn. Getting raided is extremely frustrating because players have to wait so long before they can get back into the action.
The different beds would therefore offer real benefits and allow players to unlock better respawn options by investing additional resources.
