None. 100% Support.
Initial break-in period may soften feel slightly in first 30 days.

Probability of visible body impressions developing.
Click layer to inspect.
Foam density (3.0 pcf) dictates life span by weight.
Softening and support loss often reported within 2–3 years due to 3.0 pcf foam compression.
A significant challenge for owners is the discrepancy between felt softening and measurable indentation.
Leesa's warranty requires a visible indentation greater than 1.5 inches. However, many owners report back pain (softening) long before the mattress physically sags that deep.
Warning: The warranty is void if slats are > 3 inches apart (check latest terms, often 3-4").
