If you value your health and a good night sleep, avoid a foam mattress at all costs. The foam bed is so soft it provides no back support. After a short while the mattress develops a pit in the middle where you are unable to roll from side to side. Your mid section is now positioned lower than your head and legs. If you are a stomach sleeper, forget it. Sleeping with a pillow causes a stiff neck and shoulder pain due to the height difference. To change positions, you literally have to raise your body to shift your weight to another position. This causes you to wake up constantly while losing precious sleep. I'm a side-to-side sleeper and attribute my recent back injury to the foam mattress. Over time I eventually tore disc material from my L4-L5 vertebrate requiring surgery and a long recovery. Others I have spoken with, that have a foam mattress also have back pain and lack of energy. Another downside is when you make the bed you see these two distinct deep pits left and right of center. It looks horrible. I'm Now trying an air-touch and loving it. My wife still likes a soft bed, but now she can have her head and legs at the same level as her back, without pain. I like a harder mattress and can adjust my legs lower than my abdomen, which are lower than my head. This helps settle my acid reflux and allows me to change positions easily. I feel more rested and have increased energy level.
