Which would benefit you the most while doing dumbbell chest presses? laying on the floor and doing the chest press or using a bench to do the dumbbell chest press.
Dumbells are better. You get a greater range of motion and you hit more muscle fibers like the stabilizer muscles. The muscles that you use quite often in every day life. I almost never bench press. I always use dumbells. I've seen better gains with them.
floor presses isolate the inner pectoral and shoulder and uses include toning. bench presses (more common) allow the entire pectoral to strengthen with more travel for your arms to go. Incidently floor presses are not advised as practical for minor fibromayalgia occurances.
