I tho it is a little too dark.

Hey hchendra, with the right balance of wall color and furniture I think it would be fine. If you check the before and after section on our website, there are two photos of rooms using a darker bamboo, as well as two customer photos on the product page. I hope this helps!

Hi again, as previously stated your issue is being looked into by Customer Care. Contacting them directly will be the best way to get an update on your case. Cupping is a moisture issue, as understood by any flooring company. That is not a company-specific decision. When it is properly inspected and found to not be related to moisture, this is when your warranty kicks in.
