## Before you buy

- The listing gives different construction descriptions: the title and details identify the Warner as an innerspring mattress with memory foam, while a separate description calls it a Special Edition Spring Firm model with Response Open Coils and CoreSupport. It also describes a soft knit moisture-wicking cover, while the details list polyester. Confirm the exact model, materials, and cover for the selected listing before purchase.

## In the box

- Mattress (Included)

## A good fit for

- Shoppers who prefer a firm, tight-top king mattress with innerspring support and foam comfort layers.
- Couples interested in an individually encased-coil design intended to reduce motion transfer.
- Buyers seeking a listed center-third support layer and a 12-inch mattress profile.

## Less suited to

- Shoppers who want a confirmed soft or plush feel, since the stated firmness is firm.
- Buyers who need fully consistent construction and cover specifications without confirming listing discrepancies.

## Customer feedback

The available rating evidence consists of a single rating, so it offers little basis for judging comfort or durability across sleepers. There is no customer-comment evidence to identify particular strengths or complaints. For buyers considering a firm king mattress, verify the comfort and construction details against personal needs rather than treating the isolated rating as a reliable consensus.
