This mattress was a great improvement! It’s so comfy for stomach side and back sleepers. I love the euro pillow top so it is embedded within the mattress as a whole and doesn’t stick up. The mattress has held up pretty well over time, the only thing that is unfortunate is that it has started to sag a bit in the middle. It’s not enough to cause a real problem and may be more of my bed frame. Overall very good!
