How Often Should Your Replace Your Mattress? Here are 7 Warning Signs

Your mattress has to deal with a lot of wear and tear. From dirty feet to bouncy kids and pets, to tossing and turning and spilling your late-night snacks on the cover. A bed is a big purchase and some might be tempted to squeeze every last second out of it, but there will always come a time when you’d be best served by a brand new mattress.

How do you know when it’s time for your mattress to give up the ghost? Our guide will learn how often should you replace your mattress, and what signs to look for when determining the lifespan of your product.

It Is 7-10 Years Old

  • Memory Foam

Lower density beds may need to be replaced after 4-6 years. Higher density models could last 8-10 years.

  • Latex

Organic and natural latex materials may need to be replaced after 8-10 years. Synthetic latex beds may only last 6-8 years.

  • Innerspring

These may need to be replaced by a new mattress every 3-5 years. Independently wrapped coils may also be some of the quickest to show wear, as they tend to compress much more than interconnected coils.

  • Hybrids

A high-quality hybrid could last longer than 10 years, some brands claim to last up to 15. However, because of the absorption of sweat and bacteria, along with the sagging and other traditional signs of wear and tear, it is still recommended to replace your mattress every 7 – 10 years range.

There is Sagging

When a mattress begins to sag body impressions can begin to form as the materials take longer to reclaim their original shape. Over time, this may cause mobility issues, as sleepers will have to fight to dig themselves out of the holes left behind, or they may experience issues with even weight distribution support & shape.

Bed frames with solid surfaces or slats that are closer together should help to prevent new mattress from sagging too soon. Some companies may also recommend flipping or rotating the product so that pressure is applied evenly to different areas, reducing the likelihood of impressions and sagging.

You Wake to Pain or Discomfort

If you spend a third of your life asleep, shouldn’t that time be spent in comfort & care? Of course, there may always be a health or physical issue that causes some people to wake up in pain, but if that doesn’t apply to you, you should consider a new mattress if you are frequently experiencing discomfort while sleeping.

Keep in mind that brands offer trial periods for a reason. Sometimes adjusting can be unpleasant as the spine begins to align, but people then feel a sense of relief and comfort after they adjust. Give a new mattress some time before deciding when should you replace your bed.

Firmness and Sleep Position Aren't Compatible

How frequent should a mattress be replaced? There are so many different firmness & comfort levels out there it’s easy for shoppers to get confused as to which bed is likely to suit them for a good night's sleep. Stomach sleepers, for example, might need a firm model to prevent their hips from sinking too deeply into the comfort materials. Side sleepers, on the hand, might need a softer bedding to allow compression in the hips and shoulders.

Many brands offer exchanges during the trial period so that shoppers can test out a variety of sleep positions and comfort levels to find the one they most prefer. Position preference may also change over time, in which case a new mattress might be needed.

Allergies or Asthma Worsen at Night

If you find yourself constantly waking up with the sniffles or skin irritation, you may be sleeping on a mattress that is triggering your allergies. Many people are sensitive to some of the chemicals that might be used in the manufacturing of some bed-in-a-box brands. Others are allergic to latex and might need to avoid those models.

Thankfully, there are lots of organic and hypoallergenic bed options out there that employ gentle and clean materials for better health, and an effort to relieve some of these symptoms. Many brands put an emphasis on asthma, allergy, and eczema sufferers to ensure even the most sensitive of sleepers are able to rest comfortably.

Need More Weight Support

Most sleepers’ needs change over time. Maybe you have gained a little weight or have gone from sleeping alone to sharing your bed with a new partner, child, or pet. How is the support of your bed holding up to these changes?

If your new sleeping arrangement is putting too much wear and tear on your mattress, you may need to seek one with a higher weight limit or sturdier support. The mattress market has made major strides in creating reinforced support and many brands now offer Big and Tall models to make sure shoppers of every size can find a comfortable place to sleep.

Additional Considerations

How to Prolong a Mattress' Life

Most mattress brands will offer instructions for how to properly care for their models, allowing it to last longer. Some beds can be flipped or rotated to allow for even wear and compression. Most companies also recommend a specific set-up for the mattress with suggestions on which types of bases and frames will best support.

Adjustment Period for a New Bed

A new mattress sleep surface is likely to be a bit of a shock to the body at first. You will need to give yourself some time to get used to a new spinal alignment or a different level of compression. Most companies offer trial periods that will let you adjust to the new bed before officially deciding whether or not it works for you.

Frequently Asked Questions

Do longer warranties mean it lasts longer?

Not necessarily. While a longer warranty could indicate a company’s confidence in its brand, a warranty is not a guarantee that the product will outperform others in the same market. However, some companies that offer a lifetime warranty will also allow comfort layer exchanges, which is a great way to prolong the life of the mattress.

Will the right mattress help with better REM sleep?

It’s definitely possible for a good night's sleep. If you are spending too much time tossing and turning throughout the night, you could be constantly restarting your sleep cycle, which would affect how long you spend in the REM stage. Eliminating these disruptions could provide you with a more restful experience, allowing for more deep sleep.

How often should you replace your box spring?

This may vary greatly on the construction and wear of the product. However, it is not a bad idea to simply replace your box spring after 8-10 years. You may need to replace your box spring sooner if you notice broken slats, sagging, or tears in the encasing fabric.
