What sets it apart
Level Four adds thicker contouring comfort foams to the World Class spring concept.
Our take
Consider it when you want more comfort material above the support unit. The additional foam is not a reason to disregard a better-fitting firmness in Level Three.
Reasons to consider it
A spring-centered build is worth comparing if you like a buoyant surface and change positions frequently.
The tradeoff
Spring response can make partner movement more noticeable. A pillow top changes cushioning but does not remove the underlying spring feel.
These comfort observations are editorial inferences from construction and published firmness, not results of hands-on testing.
Price and configurations
The recorded queen configurations span $1,599 to $1,799. The lowest amount applies to the least expensive configuration observed, not every firmness, height or cover.
Distinct observed queen prices. Multiple options can share one price; these amounts do not identify a firmness on their own.
For context, the Black starts at $1,799 in this catalog, $200 more than World Class Mattress Level Four. Compare the construction and firmness below before treating the difference as an upgrade.
