Frequently asked questions
Are firm spring mattresses good for back pain?
Many owners report that firm spring mattresses with good lumbar support help alleviate back pain, especially for back and stomach sleepers. However, those with chronic pain should look for models with zoned support to avoid pressure points.
How long do firm spring mattresses last?
Based on owner reviews and industry standards, a quality firm spring mattress typically lasts 7-10 years. Coil gauge thickness and foam density are key factors; heavier gauge coils and high-density foam extend longevity.
Do firm spring mattresses sleep hot?
Firm spring mattresses generally sleep cooler than memory foam due to better airflow through the coils. However, models with thick foam layers or tight covers can retain heat. Look for cooling covers or materials like latex and wool.
What firmness level is best for side sleepers?
Side sleepers typically need a medium to medium-firm mattress (5-7 on the scale) for pressure relief. A firm mattress (7+) can cause shoulder and hip discomfort, but some side sleepers prefer firmer options with pressure-relieving zones.
What certifications should I look for in a firm spring mattress?
Look for CertiPUR-US (foam safety), OEKO-TEX Standard 100 (textile safety), GOTS (organic materials), and GREENGUOLD Gold (low emissions). These certifications ensure materials are free from harmful chemicals and durable.
The verdict
The Saatva Classic is our overall winner for its durable coil-on-coil construction, certified materials, and consistent owner satisfaction.
