Been using it for 2 weeks. Still looks and feels perfect. I'm a side sleeper and it's very comfortable.

Comfortable

I been using firm mattresses and got this Sealy medium, is not too soft, is comfortable. The only thing i don't like is that tou can feel the coils when you touch the sides, and the label doesn't say it was manufactured by Sealy.
