What does medium feel mean here?

It sits in the middle of the firmness scale: enough cushioning for shoulders and hips, with support underneath. Side sleepers usually find it balanced; stomach sleepers may want firmer.

Is it good for couples?

Yes. The individually encased coils limit motion transfer, so a partner's movement is less noticeable. The coil core also gives the bed a responsive bounce.

The MoistureProtect cover is designed to wick moisture and promote cooler sleep. The coil core allows more airflow than an all-foam mattress, though room temperature still matters most.

How does it compare with the Posturepedic foam models?

The Dallas hybrid adds coil support and bounce and better edge stability than an all-foam Posturepedic. Foam versions feel more contouring and absorb motion slightly better.

Do I need a box spring?

A hybrid like this works on a solid platform, a slatted frame, or an adjustable base. A traditional box spring is not required, and a firm, flat foundation protects the warranty.

How firm is the edge?

Coil Edge reinforces the perimeter with denser coils, so the sides hold up when you sit or step out of bed. It is firmer than a standard foam edge but not rock hard.
