Pretty sure this has been suggested before, but Jorb's mega post reminded me of it.
Movable furnature that must be built in a cabin (not outside, in a cellar or cave or mine) maybe make it use wood, linen cloth and wool etc.
Using it makes your avatar tuck in for a nap.
While napping you regain stamina and SHP much quicker than normal.
While napping with a bandage on, you get a multiplier to your HHP regen that the bandage does.
Logging out while napping causes you to gain regen bonuses while logged out (maybe calculate it when you log back on?)
While you can carry beds around like other furnature, they shouldn't function outside IMO purely for aesthetic reasons.
