title: "Do You Need Coasters at All?"
lead: "If your table or desk top is wood or stone, yes; if it's glass or laminate, a quick wipe does the job. The white ring a sweating glass leaves on a wood finish is genuinely hard to remove."
recommendation:
  name: "A 6-pack of cork coasters for wood or stone tops"
  reason: "A ring stain means sanding or refinishing, while a coaster is a few dollars of insurance. For the material, our coaster-material guide stands: cork by default, plus two diatomaceous-earth pieces for sweaty summer glasses."
