Memory foam offers pressure relief and motion isolation; innerspring provides bounce and breathability; latex is durable and naturally hypoallergenic. If you’re sensitive to chemicals or off-gassing, look for CertiPUR-US or GOTS/GOLS-certified models.

Most quality mattresses are designed to perform well for 8–10 years. Signs of need for replacement include sagging, persistent discomfort, allergies, or disrupted sleep. Regular rotation (every 3–6 months) can help extend lifespan.

Mattress warranties typically cover manufacturing defects (e.g., sagging, broken coils) but not comfort objections or minor wear. Installing a mattress protector is wise since stains often void warranties. Consider adding a protection plan for coverage beyond the standard period.
