If you're on the hunt for a new mattress, you might be wondering: 'how long do memory foam mattresses last?' I don't blame you. A mattress is a major investment − you don't want to spend hundreds, or even thousands, of dollars on a new mattress only for the foam to deform in a few years' time.
Out of all the mattress types, memory foam has one of the shorter life spans – around six to eight years, when you take good care of it. Over time, your memory foam mattress will start to incur indents and impressions, creating uncomfortable lumps and bumps in your sleep surface.
