Excellent Value
I bought the Ego Black 14" hybrid on sale thinking I would replace it in a few years for a higher quality mattress. But I'm satisfied with the quality and comfort. It comes with a 10 year warranty at a 3rd the cost of its competitors. I have yet to see how it holds up over time. I'm a 220lb athletic male with broad shoulders and I have no trouble with side sleeping, or with back and pelvic support. On set up there was no awful off gassing smell. I slept on it the same night, but it takes about 3 or 4 days to come to full firmness. It needs full support underneath it for the springs to distribute weight evenly. I used plywood but a box spring would work as well. My previous mattress was a tempurpedic. I like this better.
