Explore mattress construction, materials, and durability, including foam density, coil systems, latex, hybrid layers, edge support, cooling components, and how each choice affects comfort and long-term performance.
Professor Goodsleep explains why two-sided mattresses made more sense years ago, why modern designs can weigh 165 pounds, and when dual-firmness construction still has value.

Mattress height alone does not determine support or durability. Learn what thickness ranges make sense for heavier sleepers and which construction details matter more.
Learn why mattresses may wear faster under heavier bodies and how foam quality, coils, foundations, firmness, rotation, cooling, and maintenance affect durability.
