### ⭐⭐⭐⭐ Not the worse but not the best. Somewhere in between
*by M***L on February 13, 2026*

This thing was as hard as a rock when it first showed up. Let it sit in front of the heater for 10 min to soften it up. Then I sat on it and almost broke my a** bone 🦴😂. After a few minutes though the comfort set in, but not the most comfortable. Memory Foam, more like Prison foam
