I am one of the customers Lou was referring to. Living in Northern NH the humidity level gets quite low every winter and high in the summer. Two winters ago, one of my Daedalus maple/walnut bases separated on a joint. Lou was quite surprised and took care of me. A few weeks later my wife noticed another piece of fine furniture in our home that "separated" from movement" at the joint... I think this is mostly caused by moderate to severe changes in temp/humidity.... and most of know that - but I wasn't thinking or doing anything about it at the time. Since then I use automatic humidifiers to control the climate and haven't had any more issues with movement, doorways closing stiff in rainy weather, etc. I'm in the process of installing a split AC unit with temp and humidity controls in my room and will post an update after I spend a few seasons with it.
