How Long Should a Mattress Last?

On average, you can expect your mattress to last seven to 10 years, as long as you follow the manufacturer’s care guidelines. Mattress lifespan varies based on a variety of factors, such as mattress materials, maintenance, weight, and even your sleeping style. 

The type and quality of the mattress may have the biggest influence on its lifespan. Of course, no mattress has a specific expiration date. It’s up to you to decide when to get a new mattress based on factors like comfort and support.

How Long Does a Purple Mattress Last?

The average Purple mattress lifespan is around 10 years with normal use, though you can expect a longer lifespan with our higher-end mattresses. You shouldn’t experience any Purple mattress sagging as long as it’s used as intended during that time. If you notice any sagging or unusual wear in your Purple mattress, contact us for warranty support.

Keep in mind that removing the cover from the mattress will void its 10-year warranty, since UV exposure degrades the materials. You are also responsible for any damage resulting from not using an adequate frame or foundation. Improper use or neglect of the mattress (including jumping on the bed or unsanitary conditions) will also void the warranty.

How Long Do Purple Pillows Last?

All Purple Pillows can last multiple years beyond their one-year warranty, provided you follow the care guidelines.

Regularly replacing your pillow can also play a big role in helping you get a comfortable night’s sleep. Standard pillows, such as polyester or other down alternatives, often need to be replaced every one to two years as they lose shape and support.

What Factors Affect Mattress Durability?

There’s no one-size-fits-all answer when asking how long a mattress lasts, as several factors affect your mattress’s durability.

Mattress Type

Your mattress type can have a large impact on its lifespan. For example, standard innerspring mattresses tend to have a lower lifespan, usually closer to five or six years. Always check the manufacturer's warranty to get an idea of what to expect.

• Innerspring: An innerspring mattress usually lasts five to eight years. The coils break down faster if they are absorbing a lot of weight or unnecessary stress.
• Memory foam: A memory foam mattress generally lasts seven to 10 years, depending on the density of the foam and the weight of the user. 
• Latex: Latex mattresses can last up to 20 years, depending on the materials included in the mattress.
• GelFlex Grid®: The Purple GelFlex Grid® lasts at least 10 years with proper care. 
• Hybrid: A hybrid mattress typically lasts seven to 10 years, depending on the materials and budget for the mattress. 
• Adjustable: Adjustable mattresses can last up to 10 years, but may have a shorter lifespan if you frequently adjust their settings.

Mattress Quality

The quality of your mattress’s design and materials also impact how long it lasts. The length of the mattress warranty can be an indicator of the quality of materials — a longer warranty generally means higher-quality materials were used. 

Price can also be an indicator of quality, but a more expensive mattress doesn't always mean better quality.

Care and Maintenance

Routine maintenance keeps your mattress clean and in good shape — and helps it last longer. This includes following mattress cleaning best practices (like spot cleaning stains as needed) and rotating the mattress every three to four months to prevent sagging.

Using a mattress protector can also help keep your mattress in good condition by protecting it from spills, dust, pet dander, and other hazards.

Frequency of Use

A mattress that you sleep on every night will wear out much faster than a guest mattress that’s only used every few months. The mattress in your primary bedroom will probably need to be replaced several years sooner than a mattress in your guest bedroom.

Bed Support

The bed frame or base you use with your mattress can affect its durability. For example, most new mattresses shouldn’t be used with a box spring, as it breaks down a mattress and causes it to age prematurely. In some cases, not using the proper type of support can even void your mattress’s warranty.

Sleeping Position

Your sleeping position can impact the lifespan of a mattress, particularly if you sleep in the same position and location each night. For example, side sleepers may find that their mattress starts sagging sooner in the hip and shoulder areas because of the added pressure in these zones.

Body Weight

A mattress used by two people will wear out faster than a single sleeper simply because of the extra body weight. Similarly, heavier people may find their mattresses begin to sag sooner.

Many mattresses also have a stated weight limit that you should follow. Exceeding the weight limit can cause the mattress to wear out prematurely.

Signs It Might Be Time To Replace Your Mattress

Don’t just focus on the age of your mattress. Watching for key signs of excess wear can help you know when it’s time for an upgrade. 

• Imprints: A body-shaped impression on the surface of your bed after you get up is a sign that your mattress is wearing out.
• Sagging: Visible sagging means your mattress support is breaking down. Even a 1-inch sag can create a world of hurt for your back.
• Lumps: Lumps in your mattress are caused by uneven mattress density due to age and wear and tear.
• Noise: Squeaks and screeching are signs that innerspring mattress coils are on their way out and that your support level has already decreased significantly.
• Discoloration:  Yellow mattress stains are a fairly common result of extended use over the years. Some stubborn stains will refuse to come out even with intense cleaning.
• Odor:  Mold and mildew can cause unpleasant smells and create an unhealthy sleeping environment. Mold, mildew, and dust mites can cause sneezing or coughing when you spend time on your mattress, especially if you have allergies.
• Morning aches: Waking up in pain could mean that your mattress isn't supporting you at night. Bad mattresses are notorious for causing pain in the hips, back, neck, and shoulders.
• Discomfort: Tossing and turning? An uncomfortable mattress can cause you to feel physically and mentally agitated at night.

How Often Should You Get a New Mattress?

While most mattresses last seven to 10 years, this isn’t a hard-and-fast rule. By paying attention to your current mattress’s type, quality, and comfort (or discomfort), you can determine when it’s time to choose a new mattress. If you’re not sleeping well, it may be time to make a change.

When considering how long mattresses last, make sure you get a mattress that will help you get quality sleep. All Purple mattresses feature our GelFlex Grid® (also known as a Gel Matrix™) to cradle pressure points like your hips and shoulders while keeping the rest of your body fully aligned. With multiple options to choose from, you can have the comfort and support you need.
