I have been trying to find 4x4s to build a bed. I am basically building a double sized farmhouse bed but extending the legs to turn it into a loft bed. I am having an impossible time finding 4x4s that are untreated and not cedar. I did find a place that can order in some untreated spruce 4x4s but he is telling me that spruce wood is not strong enough for the application that I want it for. He says that gluing 2 2x4s together would be even worse. The only other wood that I can find is fir which is $10/foot! That would make the bed crazy expensive to build as the posts alone would cost $240.
Anyone have any thoughts on the strength and durability of spruce 4x4s?
