My first bed was a memory foam mattress. Prior to that, I was sleeping on an old-fashioned innerspring, with stiff steel coils that used to dig into my side. I still remember my first night on a memory foam mattress: the immediate sense of relief and weightlessness.
Out of all the mattress types, memory foam is best for side sleepers, light sleepers, and anyone who appreciates soft support. Still, even the best memory foam mattress isn't perfect – all that thick foam tends to trap heat and the edge support often leaves a lot to be desired.
