I'm not to keen on our mattress, I do suffer from sore backs so went for one that supported back pain but I have not had a good nights sleep in it. There was a really strong smell off, the only way I can describe it is of damp clothes. you can smell it in the room but it is fading. I am going to have to buy a really good topper for this to give me comfort. My partner finds it the same as me but keeps saying our backs will get better in time. We are ages 43 to 46, were active but both suffer from back pain. The thickness is great and it is of good quality.
