I searched around on this quite a bit but haven't found much. A plan I am about to start on calls for 4x4 posts but the wife and I decided to make it out of red oak (we want a nice long lasting bed, everything we've made so far has been pine). Finding red oak finished in that size is near impossible. Is it feasible to use 4 1x4s and glue them together or would that be too unstable to use as legs for a bed?
