Do Latex Mattresses Sag? Durability, Impressions and Support
Latex is widely chosen for durability, but no mattress is immune to softening, impressions or support problems. “Sagging” can describe several issues: foam softening, a damaged support unit, an inadequate foundation or a true permanent body impression.
Latex softening
All foam changes with use. Natural latex generally has a reputation for resilience, but the rate of change depends on formulation, firmness, load and layer thickness.
Foundation problems
A flexible or widely spaced base can let a heavy mattress bow between supports. Follow the manufacturer’s foundation requirements, especially for queen and king sizes that need center support.
Warranty reality
Warranties usually define a measurable indentation threshold and exclude improper support or normal comfort changes. Read the actual terms before assuming any visible dip will qualify.
