Why do mattress sag and what can you do?


The most common complaint in the mattress market is the mattress sags within a short period of time. As a business that helps thousands of customers to get their new ideal mattress, we do get asked this a lot. “Does your mattress sag?” Today I am going to share why mattresses sag and some of the things you can do to prevent them.

1) Inferior raw material and skipping manufacturing steps

A good quality mattress needs to be built to endure the test of time, constant pressure and properly carry the weight of two people for over 32, 850 hours assuming the usage is 9 hours a day for 10 years. That is some heavy-duty workload.

Bigger manufacturers sometimes go in the wrong direction by using lower-quality materials such as fewer springs, thinner springs, lower density foam and skipping steps. It allows the production to be cheaper, quicker and also a lower price tag in the market to compete better. We all know the consequences. The consumers are going to suffer from an investment that provides a low return (short life-time of the mattress).

It is important to spend some times trying to understand the mattress you get. Find out what others say about this particular mattress. Review sites might not be very helpful regarding the comfort of the mattress but it can outline some common issues the mattress might have. Common concerns like getting too warm or product doesn’t last.


2) Make sure you have a sturdy bed frame / Ensemble Base

Your foundation and bed frames are crucial for your new investment (your new mattress). Seek advice from the store where you invest your money from. Make sure your existing foundation and bed frames will not void your warranty. It is important to make sure your mattress is supported on all four corners as well the middle. Make sure your slats are not too far apart (no further than 8 cm apart) and the surface of your foundation nice and flat.

3) Cover your mattress with waterproof mattress protector and quality bedding

Any liquids, fluids and water could potentially damage the upholstery of your mattress causing the top layer of your mattress compress or lose its initial support. A waterproof mattress protector is always a wise investment. These fitted sheet style protector usually are machine-washable and protect your mattress from unforeseeable events. Getting a mattress with waterproof fabric would be a nice choice as well. All manufacturers will void the mattress warranty when there are a noticeable soiling, stain and water damage. It is important to ensure your mattress is fully covered and protected.


When your mattress is coming up to the end of its life, sagging is becoming a concern and preventing a good night sleep. It is healthier and cheaper to replace a new mattress instead of adding a topper. Your 10, 11 or 12 years old mattress is accumulating millions of dust-mites, skin cell, possibly bed bugs over the years. Keeping the old mattress is usually not the best outcome for you and your family well-being. On the other hand, mattress topper may temporally improve the discomfort; however, the topper will develop the same impression over time as it is not supported by a proper mattress. Toppers are only recommended when trying to soften the mattress not covering the dip.


What do I do if my mattress still sags?

You have invested in good bedding and protections. You have ensured the foundation and bed frame are supporting the mattress properly. If you are still experiencing body impressions, it is likely the mattress is not up to the quality standard. It is best to discuss your options with the store or manufacturer. It is then the responsibility for the stores and manufacturers to honour your warranty.
