Do pocket coil mattresses offer good edge support?

Pocket coil mattresses often provide good edge support, especially models that reinforce the perimeter with firmer or higher-gauge coils. Strong edges keep the mattress from collapsing when you sit on the side or sleep near it, which makes the whole surface usable and helps with getting in and out of bed. Edge support is typically firmer on coil-based beds than on all-foam mattresses, which tend to compress at the sides.
