Best underlayment for hardwood floors is the layer that decides whether your new floor stays quiet and flat or turns squeaky within a season. A cheap underlayment fails, and the failure sounds like squeaks and wears like premature aging on the hardwood above it.
This guide reviews eight underlayments with their pros and cons, adds a comparison table, and covers the choice factors: subfloor type, comfort, moisture protection and budget. Every claim here comes from the product listings and owner feedback in the source.

Choosing Your Hardwood Underlayment
Three factors finish the decision: the subfloor (a smooth subfloor works best with any underlayment), the comfort and sound level you want (thicker gives more of both), and the budget (foam sits affordable, cork and rubber sit premium).
Material choice shapes the shortlist too: foam is affordable and effective, cork is natural with excellent cushioning and temperature regulation, and rubber is the durable, superior sound damper for multi-story homes. Thickness matters as well, since thicker options cushion more but thin ones fit under doors. Follow the manufacturer’s instructions for installation, and for the thickness question in detail, our underlayment thickness guide covers every flooring type.
