Probably someone still want to figure out when it's time to replace their mattresses.

In this complete mattress buying guide, we'll talk about different types of mattresses, budget, teach you how to choose the perfect mattress regarding your sleep positions, body types and sleep concerns. From when to replace your mattress, to the best time for your mattress purchase, we'll also cover the additional information that you may consider when buying a new mattress.

When to Replace Your Mattress

Most mattresses on the market come with a 10-20 years warranty, but it doesn’t mean that your bed will stay as comfortable as it has been for a decade. In particular, after several years of use, the top layer of your mattress may prone to wear out and sag or soften, and buying a new mattress is a smart thing to do when it no longer gives you the proper support. 

In addition, some signs suggest you need to replace your mattress:

+ It is over 7-8 years old;
+ A significant change in your weight or sleep position;
+ Wake up with soreness and stiffness;
+ Your allergies are getting worse;
+ Difficult to fall asleep;
+ Noticeable or visible signs of wear, like sagging, holes, irremovable stains, tears, or ripping;
+ Your bed tends to squeak or creak.

What Type of Mattress You Want 

+ Innerspring Mattress

The innerspring mattress we refer here is the most popular and oldest model made with spring layer(s). Its core support system is thick metal springs or coils. This type of mattress has a thin comfort layer of materials like latex, foam or other natural fabric, or sometimes has no extra layer(s) above the springs and provide an overall firm feel and solid support.

+ Hybrid Mattress

To get more cushioning and contouring, mattress manufacturers combined springs and foam to create the hybrid mattress that delivers the balance of support and comfort to some extent. Hybrid mattress is a good option for those who prefer the feeling of both coils and foams can offer.

+ Foam Mattress

Memory foam mattresses combine layers of memory foam and other types of high-density foam to offer both softness and support. It is made of a polymer, also known as polyurethane, which can slowly recover its original shape after compression and become softer and softer as the temperature rises. Memory foam mattress can closely cradle your body, while protect your spine. 

+ Latex Mattress

Latex mattress is loved for its durability, pressure relief, and sustainability. Natural latex is made from the sap of rubber tree, and the whole production process is eco-friendly, with less chemicals used. Latex mattress is also naturally hypoallergenic and mold-resistant.

Select Your Mattress Firmness

What’s Mattress Firmness? Simple. The firmness, or hardness is the feeling that you lay on a mattress, and it can be soft or hard. That means it’s subjective and might be slightly different from person to person. The methods that many mattress manufacturers use to measure mattress firmness might differ, but commonly in mattress world, we use a 10-point scale to describe it. The highest number means the hardest level, and the slowest end, the softest.

Firmness LevelFeelCharacteristics
1Extra SoftClosely conform to your body and sink significantly.
2-3SoftConform and sink considerably.
4-5Medium SoftConform fairly closely and sink some.
6-7Medium FirmConform moderately, but do not sink much.
8Slightly FirmStill conform comparatively but sink less.
9FirmMinimal conforming and sinkage.
10Extra FirmVirtually no conforming and no visible sinkage.

Your sleeping styles, body weight and unique sleeping concerns are key considerations when determine the most suitable and comfortable mattress firmness. For example, light-weight people tend to place less pressure to the bed surface and sink less, that is, they would feel firmer than the average-sized and heavy weight sleepers when sleeping on the same mattress. Therefore, softer mattresses are better for light-weight sleepers, rather than plus-sized people. For more info about how your body weight and whether sleep with pain influence your choice of mattress firmness, please see: Mattress Firmness Guide.

Some people tend to believe that a firm mattress is always more supportive than the softer, which is not exactly true. They are different. Support indicates that a mattress promotes the proper alignment of your spine. 

Your Unique Sleeping Concerns

There is no one mattress that fits everyone. Apart from choosing the right mattress types, mattress size, height and firmness, the other essential factors like your preference and unique sleep concerns are also important when buying a new mattress. Below are some tips for choosing the most suitable mattress regarding some popular sleep concerns.   

How to choose a cooling mattress for hot sleepers - Most people revel in the summer months, but warm nights can be a problem. Sleeping hot can be uncomfortable, and you may not get the rest you need. There many reasons why people prone to night sweats-it maybe climate changes, the heat emitted from your partner, thick blanket, or, may be your mattress retains too much heat. If you are a hot sleeper, you should look for a mattress that can actively cool you down, or allow a lot of airflow, or both.

How to choose the best mattress for lower back pain – Lower back pain has become a common problem that sleepers suffer in their morning. The reasons that cause it might be improper or not enough support on the lumbar region. Therefore, a mattress that closely cradles your body curves and gives adequate full-body support is the best bit for lower back pain sufferers. We would recommend medium firm memory foam and pocketed coil hybrid mattresses which delivers the best of both worlds, and features enhanced edge support for getting in and out of the bed easily.

How to choose the best mattress while pregnant - As the baby grows, pregnant women’s preference for a mattress will change. They put more pressure on the mattress, so a mattress that close contouring and constant, generous pressure relief without sagging under the extra weight is needed. Some may prefer a flippable mattress or toppers because in the middle and late stages of pregnancy, doctors recommend that mother-to-be sleep on their left side.
