How Long Does a Tempurpedic Mattress Last?

The Swedish made Tempurpedic mattress is popular and pricey - but how long does a Tempurpedic mattress last? This memory foam mattress is composed of billions of tiny air cells. The weight of your body compresses these air cells and spreads the air pressure to adjoining cells.

As you move the air flows back into compressed cells and they quickly regain their previous shape. It is this air cell technology that allows Tempurpedic to provide total comfort with excellent support.

What makes Temperpedic mattresses stand out from other memory foam mattresses available on the market today is the high density foam used by the company. Most memory foam mattresses use 3-4 pound density. The word "pound" is used to measure density because this viscoelastic foam increases in weight as it increases in density.

A standard memory foam mattress made with 2.5 pound foam is heavier than a standard traditional mattress. The use of 3-4 pound density foam increases that weight even more. The level of density is a reflection of the number and size of the air cells that make up the memory foam.

Tempurpedic uses an astounding 5.4 pound density for its product. This density packs billions of tiny cells together and the result is a supportive foam mattress that is quite heavy. This creates a form that is firm for support but provides the luxury of comfortable softness.

This also makes Tempurpedic mattresses quite expensive. Prices begin at $2000 and go up from there. Even a Tempurpedic mattress topper tops out at about $1000.

Density Affects How Long Does a Tempurpedic Mattress Last

In inexpensive memory foam with low density, the bubble of air that are used to create the foam product are larger. The amount of air in the foam is higher and the small bubbles will collapse quicker. A low density memory foam mattress may need replacement in a little as three years with daily use.

As the cells begin to collapse the foam flattens somewhat. Often a cheap memory foam product will disintegrate in quality rather quickly once it begins to lose shape. Often a crevice or low spot will develop either in the center of the mattress or in the area most often used by the sleeper.

The foam becomes softer as the air support pockets split under the strain of weight. If the owner is obese, a cheap memory foam mattress will not keep its shape for long.

Tempurpedic uses foam of high density through the mattress. Even when the air bubbles near the surface (and most compressed by a sleeping person) begin to show signs of weakness, the billions of tiny air bubbles below still provide good support for years.

The comfort found in a memory foam mattress is due to the material's ability to conform to the contours of your body. When you lay on your back, the foam cradles your legs but allows your heels to rest deeper. Elbows and shoulders avoid the resistance offered by firmer mattresses and the heat from your body makes the foam even more pliable.

With Tempurpedic mattresses it is your body's heat that helps the dense foam mold comfortably and the mattress gains in comfort as it reacts to body temperature. Unfortunately, the mattress also holds more heat than memory foam of lower density. This has led to some consumer complaints but doesn't seem to be a major defect unless you live in a hot climate without air conditioning.

The heat retention could be a real problem for overweight people or for those who tend to sweat easily or profusely. Some customers have reported better results with Temperpedic when they use the optional cover that prevents the mattress from being exposed to dampness as it seems to improve the lifespan of the memory foam.

The Guarantee

The Tempurpedic guarantee has been the source of many consumer accolades and complaints. There are reports of great customer service and of a company that responds well to consumer complaints and also claims that the warranty is hard to use if the product doesn't meet expectations. If you are concerned about how long does a Tempurpedic mattress last, examine the warranty in detail to be certain you fulfill any required obligations.

Tempurpedic mattresses come with a 20 year warranty which appears to be comprehensive. The buyer is protected from defects in manufacturing, of course. This 20 years warranty also covers deterioration of the mattress as long as it has been used properly and supported with a good foundation and bed base.

How long a Tempurpedic mattress lasts depends in large part on how it is placed. The warranty clearly specifies the need for good structural support for this heavy mattress and advises against using a standard slat style bed frame without additional support.

Determining Durability

Tempurpedic offers different levels of firmness and its likely consumer complaints about the mattresses losing shape involve the softer mattress options and mattresses without covers. The most luxurious Tempurpedic mattresses have coverings to protect the foam from dirt, dust and wetness and are the highest density memory foam mattresses available.

How long does a Tempurpedic mattress last is a valid concern due to the high price of the products. With prices that begin at about $2000, this is not a mattress you want to replace every three or four years.


Though the products are warranted for twenty years, most people don't plan to use a mattress for that length of time before replacement. If memory foam is your mattress of choice, Tempurpedic is definitely a good option.

The high density foam results in a foam product that keeps it shape for many years when properly supported and kept clean and dry. Most who have Tempurpedic recommend choosing the 10 inch mattress over the 8 inch product and this seems to improve the life of the mattress.

The need for proper support from a good foundation designed to handle the weight of a Tempurpedic mattress and a bed frame that provides solid support as well is highlighted by the manufacturer several times on its website.

How long does a Tempurpedic mattress last? Many consumers say they have been using their mattress for ten years or more in complete comfort. When you break down the price of this high density memory foam mattress brand, the cost per year for a good night's sleep is well worth it for many loyal customers.
