very disappointed

I had this mattress delivered a year ago on Sept. 11, 2025 and I waited a full year to write this review because I really wanted to give this mattress a chance and like it. Especially after spending almost $5000 on it. I’m a side sleeper and sleeping on this mattress was torture. My shoulder and lower back were chronically sore and because I tend to sleep in the same position permanent divots formed in the mattress which my body would slide into. I rotated the mattress because it can’t be flipped and that helped for a bit but then new divots would form. I replaced this mattress today.
