(Image credit: Future)When you lie on your back or front on a softer bed, your hips tend to sink lower than the rest of your body. This puts pressure on the spine and can cause long-term discomfort.But a firm bed, like the Plank mattress, keeps those hips lifted. It's particularly good for stomach sleepers (our best stomach sleeper mattress guide is dominated by firm beds). Stomach sleeping already puts your spine in odd positions — you don't want your mattress to make it worse.Strong from edge-to-edgeEdge support refers to how sturdy a mattress is at the perimeter. Strong edges allow you to stretch out and make it easier to climb in and out of bed. Firm mattresses don't always have good edge support but the two do tend to go hand in hand (when there's less sink in general, the edges are less likely to collapse).The Plank Firm has exceptional edge support. I always sit on the side of the bed while getting my bearings in the morning and on the Plank, I could believe I was sitting on a chair. These are sides you can park a truck on.More firm mattress sales to browse today...
