Why you should replace your mattress sooner than later.
How long your mattress lasts depends on how often it’s used and what level of quality it is, but in general a mattress set that is seven years old has started reaching the end of the line and might need to be replaced. While this is a good rule of thumb, everyone’s body changes over time and your need for comfort and support increases as you age. Your body may be ready for a new mattress before the 7-10 year mark, so listen to what it’s telling you. It’s a good idea to compare your mattress and foundation to newer models every few years to see if there is a set that feels better to you and offers features you may not have needed or looked for in the past.
How do I know if my mattress needs replacing.
Good sleep is very important for your health, productivity and ability to feel your best. Check in with your mattress regularly to find out if you need a replacement. You may not even be aware your mattress has gotten old and worn until you think about it. Here are a few signs that you may need a new mattress and foundation:
You wake up with stiffness, numbness, aches and pains.
You realize you got a better night’s sleep somewhere other than your own bed (such as at a hotel)
Your mattress shows visible signs of overuse (it sags, has visible tearing, ripping, holes, staining or damage)
You are tossing and turning more throughout the night than usual
Lumps, bumps and uneven surfaces
You are usually tired despite getting a full night’s sleep
Your mattress is seven years old or older
I have a bad back, should I buy the firmest mattress I can find?
Comfort is very subjective, however, purchasing too firm of a mattress can create pressure related issues and cause you to toss and turn more, never allowing your back to heal and relax.
Key terms
- Pressure-relieving: reducing the amount of local felt force against a body part
- Partner disturbance: when a person's movements wake their partner up
- Adjustable Base: replaces a boxspring/foundation to a bed and can elevate head and feet of the mattress

Frequently asked questions
Should I buy a softer or firmer mattress?
Comfort is a personal choice and no two people are exactly the same. The goal for choosing a mattress is to provide enough pressure relief so you aren't tossing and turning, and support that matches your individual needs. As we age, generally we should add more pressure relief.
What happens if I buy a mattress from you and it's too firm (or soft)?
Fosters Mattress has a 120 day sleep trial which will give you plenty of time to evaluate your needs. New mattresses will slowly soften up over the first 30 days, so it's best to give it at least that amount of time before making a decision.
Should I consider an adjustable base for my new mattress?
Elevating the head can reduce acid reflux and snoring, while elevating the legs promotes better circulation and relieves lower back pressure. You can Customizable Comfort, adjustable bases let you fine-tune your sleep position to the exact degree you find most relaxing. They also make sitting up to read, work on a laptop, or watch television incredibly comfortable.
