Mattress in use for less than a month, but so far so good. Medium mattress feels soft but is still supportive. If you like medium-firm, definitely get a firm. This is not close to medium-firm. Mattress edge has a lot of give when sitting or getting on and off, but springs back into shape. Price with discount was more than wanted to spend, but the mattress seems to be of good quality and time will tell how it stands up to wear and tear.
