The time to replace the mattress mainly depends on its quality, use, and maintenance.

How to Tell When It's Time to Buy a New MattressGetting a good night of sleep may seem like a difficult task. You may be one of the millions of people who toss and turn all night long and cannot get a good night of peaceful rest. A lot of people blame their sleeping patterns on an inability to fall asleep or insomnia. Unfortunately, most of the time, your mattress and the condition that it is in is often to blame when it comes to not getting a good night of sleep. This is why you may want to consider buying a brand new mattress so that you can sleep a little easier during the night.While many nighttime problems can be blamed on the condition of your mattress, there are still times when a person may have insomnia and even a good quality mattress will do nothing for it. This is when it comes in handy to know when and if you should start considering buying a new mattress for the bedroom. One thing to look for in a mattress is if it appears lumpy or if coil springs inside pop up in different areas, making it uncomfortable for you to sleep on. In general, if the mattress is very uncomfortable to sleep on during the night, this is a good indicator that you need to buy a new mattress.Another thing to look for when considering buying a new mattress is if your old mattress has a lot of stains or has an odor to it. Many times, cleaning cannot get rid of deep-set stains and odors can accumulate over the years of owning a mattress. If the mattress is incredibly lumpy, stained and also has an odor, you should buy a new one. Buying a new mattress does not have to be expensive and should be something that is easy and worthwhile for you to do. You don't necessarily have to purchase the top of the line mattress on the market or visit a store that has salespeople swooning all over you to sell you the most expensive thing in the store. Just find a mattress that you are comfortable with and one that is easy to afford.

If you have a set of box springs you should replace them when you get a new mattress as they wear out. If you have a foundation (rigid platform) and it is in good repair and sits flat you will get just as long a wear out of your new mattress as you will with a new foundation. It will probably void your warranty, but if you bu a decent mattress and take care of it you most likely will have no issues. You should not use a box spring with a bed designed for a foundation as it will wear prematurely. over 90% of the beds made today have foundations. Also a bed designed for a box spring should not have a foundation used on it. The innerspring on a platform and box spring bed are designed differently.
It depends on your budget and what kind of mattress you want. A good innerspring mattress will run around $700, and a good foam mattress will run about $1000.
dont bother, scrap the mattress and buy a new one
