We made this bed in the king size. DEFINITELY sand each shim prior to gluing it down. It is definitely no fun rolling over in the night and hurting my hand on the rough shims. I would also recommend staining the headboard (the base for the shims) prior to gluing down shims so that any holes between shims blend in with the stain color underneath. We did not and there are a couple spots that you can see the plain wood under the shims. Also, we did what they recommended in the plans to secure the side rails. The bed is not very stable and squeaks. We keep talking about altering it somewhat, but it's so dang heavy that we have been putting it off. One other thing that I wish we had done would have been to sand off the corners of the end of the footboard. We've gotten a few bruises from walking into the ends. It cost more than we expected and it took longer. But overall, we love it and are very happy with it. Just wish we had known now to do some things differently.
