Sealant to Block Smell of Wood

I recently purchased a wool bed from Shepherd's Dream and am waiting for it's arrival. I have an ash platform bed from Bedworks of Maine. The slats are unfinished but I find the natural odor of wood bothersome. I have already put them in the sun and it helped some, but not enough. Can they be finished or sealed with the shellac you recommend or something else so I can't smell the wood or would this compromise the mattress?
