Did I just get a dud or are most (cheap) memory foam mattresses like this?
Back in August, I got this mattress on Moofi:
I was quite happy with it after a couple weeks of use:
But now, I've noticed a permanent dip/softer spot in the middle (right where the bulk of my body usually is) and some other spots that aren't bouncing back. It's quite uncomfortable, creating different, odd-shaped areas of support on my body, and I've been waking up sore and tired for a week now. I find myself sleeping at the very left or right edge of the bed just for some support. Since I've had it, I've rotated the mattress 4 times (can't flip—memory foam is only on one side) and I did the research on the type of frame to use.
Pretty bummed considering I've had this mattress for only 6 months and will need to buy something ($$$) else. Anyone with similar experiences?
