Why do cheap bamboo sheets and expensive ones look so similar?

Many bamboo and eucalyptus sets are produced from comparable base fibers, so a $40 set and a $200 set can feel similar out of the package. The premium picks tend to justify their price through weave (e.g., sateen), deeper pockets, finishing, and brand warranty rather than a fundamentally different material. Reviewers note that long-term durability and pilling resistance are where price differences sometimes show up.
