full size innerspring mattress

Most full-size innerspring mattresses in this selection measure 75 inches long by 54 inches wide; one listing measures 74 inches by 53 inches.

These mattresses use several coil types, including pocket (individually wrapped) coils, continuous coils, Bonnell coils, and tri-zone pocketed springs for targeted support.

Many listings highlight cooling features such as cooling technologies, gel-infused memory foam, airflow-ventilated designs, and the open spring structure, which promotes better airflow.

Warranty lengths shown include several 10-year limited warranties (sometimes described as "worry-free") and some shorter limited warranties such as 90 days.

Features that improve motion isolation and targeted support include individually wrapped (pocketed) coils, tri-zone pocketed springs for extra lumbar and edge support, and memory foam layers that contour to the body and reduce motion transfer.
