Very comfortable
[This review was collected as part of a promotion.] Have used this for a little over a week now and we are happy with it. It's not hard but not too soft, great for the wife that prefers soft and myself which prefer harder. Good in between. Measured about 10.5 inches after letting it air out for about 3 days. There was a slight smell during initial opening of packaging but it disappeared by day 3, or we didn't notice it. Seems durable with the springs, I feel like it will last several years, compared to these new mattresses in boxes.
