double bed mattress

Listings use standard U.S. mattress sizes. A Full (often called Double) is shown as 75" L × 54" W, and a Queen as 80" L × 60" W. The search results also include Twin and King dimensions alongside these sizes.

The listings describe a range of firmnesses, most commonly Firm and Medium-Firm. Some listings also use terms tied to material feel, such as a 'memory-foam' or 'medium hardness' sensation.

Several listings highlight cooling features such as gel-infused memory foam, breathable covers or fabrics, and other airflow or heat-dissipation technologies (some listings also mention green tea–infused foam for freshness/airflow).

The results include both all-foam mattresses (noted as 'No Coils') and coil-based designs such as pocket or individually pocketed coils. Both construction types are represented in the listings.

Many mattresses ship compressed in a box ('mattress in a box') and expand after unpacking. Listings commonly state that initial expansion happens within hours and advise allowing about 24–72 hours for full expansion.
