I didn’t know a mattress could be so heavy! That was a surprise. We needed to replace an old pillow top, and I had a memory foam mattress when I was single, and it was hot, but I remember newer beds coming out with cooling gel. I like the stability of the coils but the support of the foam. I have a horrible back and my hips are awful. My last few mattresses took some getting used to. A few weeks of discomfort and it felt better. This bed felt great the first night. My back never hurt once. The price is INCREDIBLE. The color is even nice. Why did it take so long for someone to figure out mattresses can be more than white lol. The best mattress I’ve ever slept on.
