We have been experiencing some condensation issues with the cushions in Taj, kinda common from what I have read. At any rate, we bought a product called Hypervent and I just finished a quick blog on the install with pictures. If anyone is having similar issues, this may be a solid answer. You can get to the blog via the link in my sig.
Hope this helps someone
