Memory Foam and Latex Mattresses Require More Support Than Traditional Innerspring Mattresses
Terra Foundation vs Regular Box Spring
Regular Box Spring
- Limited Support – Can cause mattress sagging over time.
- Shorter Lifespan – Wears out faster than solid wood foundations. Traditional box springs last 8 years on average.
- Poor Airflow – Traps heat and allergens, reducing mattress freshness and longevity.
- Noisy Over Time – Springs can squeak and lose tension, contributing to sag.
- Bulky Design – Often outdated and less visually appealing.
Terra Mattress Foundation
- Eco-Friendly Materials – Made in the USA from solid, natural wood with no harmful chemicals.
- Better Mattress Support – Slatted design prevents sagging, unlike box springs.
- Long-Lasting Durability – Stronger and quieter than traditional box springs.
- Healthier Sleep – Improved airflow reduces dust and allergens.
- Sleek Design – Modern, minimalist look compared to bulky box springs.
