Its like putting a lid on a can of liquid. You do have a moisture problem. Could be something as simple as putting a layer of visqueen under your crawlspace. Your getting moisture and until you find the 'problem' your flooring will continue to have the same problem.

I have to agree with the majority here and say my preference would be to avoid putting any material that is faux next to it's real counter part. Fake travertine tiles next to the real stone, laminate with a granite look next to a granite counter, and vinyl wood look next to real wood flooring. I think each has it's own place and look nice on their own, but they shouldn't be installed next each other. I also have to agree about the wood floors. We have Brazilian walnut in our kitchen and it's held up great. Our electricity went out once for 4 days, the fridge leaked water all over the floor and we thought for sure it was going to require replacing. Within a matter of a couple of days, it had dried out completely and looked good as new. I love having the wood in our kitchen and doubt I'll ever have anything else. If the only reason you are putting vinyl in your kitchen is because you don't feel it's a good fit please reconsider; I think you'll be pleasantly surprised.

I think darker chairs or even painted chairs would look much nicer than trying to match your new table. I have an antique cherry table that I refinished, an antique oak hutch that was an anniversary gift from DH 15 years ago. I used two sets of mismatched chairs with it for many years but they were deteriorating to the point that the wood glue no longer held them together. Last August I ordered chairs from EA ina French Grey and I love how everything looks together even though none of it matches. I am attaching a pic and apologize in advance to those of you that have seen it so many times that your sick of seeing it.

I did give that a bit of thought, lovemrmewey when I decided to give up the first floor bedroom to add more living space in the kitchen area for today. If need be, I can reconfigure another area of the first floor for a small bedroom if one is required in the future. For now...I am holding a vision that I will be healthy and able to manage stairs to an upstairs bedroom. Both floors will now have bathing/showering options. In the past, that was only on the first floor.
