This mattress is an excellent value. I like the way it gives support & doesn't sag, especially when two people are sleeping & one of them is heavier than the other. I have frequent lower back pain & I find that the support I get keeps my back from being twisted or pulled while I sleep. I purchased the medium support, which I think was a little too firm for my preference. However, I placed an inexpensive mattress pad on top & now it is just the right feel. No more traditional mattresses for me....I would definitely purchase this mattress again, but maybe in the soft version.
