Lull

When it comes to on-demand mattresses, Lull really did it right. They offer the ease and convenience of ordering their bed-in-a-box with the security of a risk-free 100-night trial, which was more than enough to get me in bed with them. I was sold on the comfort immediately -- no ease feat for a guy that suffers from chronic back pain. But their not-too-hard, not-too-soft memory foam did the trick from day one, and I've been sleeping better for it every since.
