Its really hard to say which will last longer between a mattress and a matress pad. Since mattresses only have a lifespan of 5 to ten years typically I would say matress pads because they don't wear out like a mattress does.
This mattress pad can be machine washed and dried.
It depends on the thickness of the pad, if the person using the pad is overweight, and if the mattress underneath the pad is already worn out and sagging or lumpy. Most pads last 1.5-3 years.
Most mattress pads have elastic sides to hug the mattress or are designed like a fitted sheet. If your mattress pad isn't made like that it may be time to buy a new one!
