This mattress was amazing for the first 2 months. Then it quickly became softer and softer. By the 3rd month, the section where I slept had become too soft and no longer felt firm at all. This is NOT a firm mattress, even when new. I had several of my friends try it, all of them said it was plush. I agree, the pillow top is so thick that it feels plush. This was a positive at first, when the underlying support was firm. It felt comfortable and supportive. but when the support started to soften, now this is just a soft saggy mattress. My hips sink down 6 inches causing terrible back pain. In the beginning, my hips only sunk down 3 inches. I'm disappointed. I only weigh 155 pounds, there's no way it could be due to my weight. Just another cheap mattress that doesn't even last 3 months before losing it's form.
