I got mine about two months ago. Bought it because it was advertised as a regular coiled mattress that is flippable and very firm. First, it’s huge, thickest mattress I’ve ever had, a little issue with some of my fitted sheets but that’s okay, I can buy new ones. Makes my bed really high off the ground, like I have to climb a little to get up there, but I like high beds. The first week sleeping on it I hated it. Hated it but my back soreness went away immediately so I stuck it out. The top most layer was just too soft for me, I even double checked my order to make sure I had ordered and received the right one. Then, after about a week, I got used to it and now I think it’s the most comfortable mattress I’ve ever slept on and I look forward to curling up in bed.
