Why Wool Is Used in Latex Mattresses
Wool is commonly used in natural-material mattress covers and can serve as part of a fire-barrier system.
What matters most
Focus on the whole mattress design rather than a single material label. Firmness, layer thickness, support core, cover, and sleeper characteristics work together.
How to compare options
Use current product specifications and trial policies. Avoid choosing from marketing terms alone, especially when comfort labels are subjective.
When Spindle is relevant
Spindle is most relevant when adjustable firmness and an all-latex option are priorities. Its current Organic Latex Mattress uses rearrangeable Dunlop latex layers.
