But just an FYI for those who even use a UTH correctly. If you place this on your wood furniture due note that the heat will take all the moisture from the wood and will at some point warp and or split the wood it is on.
This will take quite some time but will happen. I was a cabinet shop guy and know what happens to wood with long periods of heat. Just a heads up.
If you can once in awhile to keep the wood nice re-seal it or orange oil it to keep the wood from doing these things..
But enough on wood..
