I've slept on this mattress for 2 weeks now and have been loving it. I have a frame that doesn't require a box spring. This mattress sits well on my bedframe and feels the perfect level of firm for me. My previous was a pillow top and it's a big difference in a good way. I hope this mattress will support my back as I'm old LOL. As far as temperature regulation it is just starting to warm up now for summer so I'm hoping this mattress doesn't hold too much heat. Also, It's hard to tell right now how durable it is but it feels like average durability for previous mattresses that I've owned so far. I will update in a few months if it starts wearing down.
