What does humidity do to a floor under a rug?
Wood moves seasonally. Under a solid synthetic pad, that movement happens against trapped moisture. Under breathable felt, the floor exchanges with the room like the rest of the house.
What about sand?
Sand is the real enemy in a beach house. A pad lifts the rug enough that grit falls through the pile rather than grinding between rug and floor every time somebody walks across it.
Does salt air affect the pad?
Not a latex-free felt one. It is the rubberized backings that degrade fastest in warm, salty, humid air — another reason the Daisy Grip holds mechanically rather than chemically.
