As far as quality, Cultiver is always excellent. However, the reason I'm giving such a low rating is because I had previously ordered their fitted sheets and pillowcases and wanted to buy a matching flat sheet after the fact. Upon arrival I realized that their "natural" flax color was a darker color compared to my previous order, completely defeating the purpose of getting a flat sheet to complete the set. When I reached out to customer service, they essentially said that there was nothing they could do other than return the order and hope for a lighter color but with no guarantees. It's made it very hard for me to know how to proceed. Do I return it and hope for the best? Do I just accept it and have mismatched bedding? Mind you, Cultiver products are NOT cheap, and so the idea of buying all new bedding just to have a matching flat sheet, seems ridiculous but nonetheless, it's a very frustrating predicament.
