How long should a mattress last?

If you are thinking about investing in a new bed, or replacing a current one, you may be wondering how many years it is supposed to last. When it comes to weighing up your options, an important factor to consider is mattress lifespan. How long your bed lasts is an indication of its quality and your overall return on investment.

A good mattress ought to remain in good condition for at least 7-10 years. If you buy one that only lasts for 5 years, you’re only getting half as much value compared to if you bought one that lasts for 10 years.

Sealy Posturepedic, awarded Canstar Blue’s “Most Satisfied Customers” Award in 2018 and 2017, works with an industry-leading Research & Development team that is dedicated to designing and testing quality bedding.


How often should you replace a mattress?

There is no single rule or definitive timeframe that works for every mattress. The construction methods and materials differ from brand to brand and amongst different models. Some beds may deteriorate faster than others depending on how frequently it is used and whether it is maintained according to care instructions.

Aside from being a place to sleep at night, your bed serves another important purpose — it should provide the necessary support so your body stays properly aligned at night. This is critical so your muscles can relax and you get a restful night’s sleep.

Over time, the infrastructure of the mattress will begin to deteriorate. As a result, the support it offers may also decrease. When that happens, you may find it more difficult to get comfortable; you may start tossing and turning and could even wake up with pain (often in the lower back or on pressure points).

If you are experiencing any of these symptoms, think about how many years it has been since you purchased your current mattress and inspect it for signs of sagging or deterioration.

Tips for a longer-lasting bed

Know the Guarantee information

First, read the guarantee information so you understand which parts of the product are covered. Then, periodically check to see if any of those parts malfunction — if they do, we can take action to quickly repair them. It also helps to be aware of what voids the warranty so you can take preventative action.

Moving the mattress

When you receive your mattress, carry it on its side with the help of another person. Be sure that it never gets bent. Additionally, while there are handles, avoid using them for lifting or carrying the mattress; they are designed for positioning that mattress once it’s on the foundation.

Prevent jumping

Once the mattress is in place, try not to let anyone jump on it. While it will be soft and a bit bouncy at first, jumping can damage the bed’s infrastructure. If the mattress is damaged from abuse of this nature, the warranty will be voided.

Keep it clean and dry

Another important tip to maximise your Sealy’s lifespan is to keep it clean and dry. Purchasing a mattress protector is a great way to do this. It may be a good idea to place a waterproof sheet or cover underneath the protector on children’s beds.

Choose a supportive foundation

The foundation also plays an important role in maintaining the quality of your bed. If the base does not provide adequate support, it can cause the mattress to sag. Sealy provides foundations which are designed to correctly support their corresponding mattresses; however, if you are going to use a non-Sealy foundation, you will want to ensure it is in good working condition.

Rotate it properly

Lastly, Sealy’s mattresses are one-sided, which means they cannot be flipped. However, they should be rotated head-to-toe periodically. Body indentations are normal after some time, so rotating it will prolong the support and comfort it provides.

The Sealy guarantee

When you make the decision to buy a Sealy, you can rest assured that it is made to last. With our guarantee, you will be able to use your mattress for at least 10 years — and if cared for properly, it will likely stay in excellent condition for much longer. Some customers have claimed their Sealy mattress lasted them three decades!

The 10-year guarantee covers coils or wires that are loose, broken, protruding or torn. It also covers the foundation if wood splits in the frame, modules compress, legs and castors fail, or foundation wires break through any fabric.

With this guarantee, you can rest assured that you will have a mattress in good working condition for the next decade. If you are concerned about lifespan, consider a Sealy mattress for durability, comfort and support.

Sealy mattresses are built to last

When looking into how Sealy mattresses are made, you will find that each state in Australia has its own factory to meet local demand. You won’t find any warehouses full of imported products, because each one is made to order. This investment into local manufacturing supports the economy and its local people; employees return the loyalty with devotion to their craft. The highly tenured craftsmen and women have decades of experience and are the best at what they do.

Once the mattresses are made, they undergo rigorous testing by the Sealy Research & Development Centre, a NATA-accredited testing facility. Each element must comply with stringent Australian quality standards. This process includes testing raw materials and components; they undergo an initial series of quality tests, followed by ongoing testing to ensure consistent performance and durability. In addition to raw materials, Sealy tests the finished product, too. Every piece of bedding that leaves manufacturing adheres to benchmarks for durability, comfort and support.

By taking the time to ensure each product is up to standard, Sealy can consistently provide customers with high-quality mattresses that are built to last.
