Products like sofa, mattresses, etc. containing polyurethane may cause yellow discoloration of the entire foam block. This is because the polyurethane material itself has a property of turning yellow, depending on UV irradiation, temperature, and humidity.
As we have concluded, the yellowing of memory foam is a natural process that cannot be stopped. However there are ways to help slow this yellowing down to keep your mattress better for longer. You can slow this yellowing down by ensuring that the mattress is rarely exposed to sunlight.
It's normal for mattresses to get yellow over time, especially without a protector. It's mostly from body oils and sweat. Keep using the protector and try cleaning the mattress with a mix of water and mild detergent. Regular sheet changes will help keep things fresh. You're not alone in this!
Natural Oxidation
Yellow stains from oxidation don't have a smell and persist despite regular cleaning. Oxidation is natural and will eventually happen to any mattress, especially memory foam ones. However, you can slow oxidation down by keeping your mattress away from moisture and out of direct sunlight.
containing polyurethane may cause yellow discoloration of the entire foam block. This is because the polyurethane material itself has a property of turning yellow, depending on UV irradiation, temperature, and humidity. You can rest assured that being yellowing is a natural phenomenon.
Sweat and Sebum
It's a fact that everyone sweats and releases natural body oils while sleeping. Although sweat stains may not be visible immediately, they gradually accumulate, leading to unsightly yellowish stains. Sweat and sebum provide an ideal environment for bacterial growth, which can cause unpleasant odours.
Quality sleep is essential for our overall health, and a good mattress plays a crucial role in ensuring a good night's sleep. Experts recommend replacing your mattress every 6 to 8 years, but there are factors can influence this timeframe.
Without a mattress protector in place, yellow stains caused by sweat, body oils, urine, dust, dirt and other debris will begin to build up. Hydrogen peroxide is a powerful cleaning solution that helps shift stubborn stains in minutes. However, if you don't use it properly, you could cause lasting damage to your bed.
Mix one part baking soda and two parts cool water to form a paste. With a cool, damp cloth, apply the paste to the stained area of the mattress and lightly dab, working the paste into the stain. Let the paste dry for 30 minutes. Repeat the process with a cool, damp cloth.
Natural discoloration over time due to oxidation is completely normal for foam However, proper maintenance and care are required to reduce stains and discoloration not related to oxidation.
Rotate the Bed
However, you can still try to fix it. Rotate your bed so that you sleep in the opposite area of the mattress. This will cause a counter-pressure, eventually evening your sagging mattress. Again, please give it a few days or weeks for your mattress to return to its original shape.
Is memory foam ruined if it gets wet? Short answer: yes. You should always avoid getting your mattress wet. Moisture in memory foam will weaken its viscosity.
The main weakness of memory foam is its vulnerability to heat and water. You should never machine wash memory foam, as this will damage the fibres and cause it to lose its structural memory – it may also become lumpy and uncomfortable. For the same reason you should never steam clean memory foam or let it get too wet.
Blot away any excess liquid with a clean cloth and allow the mattress to dry completely. If the stain is stubborn, use a pinch of baking soda on top of the stain and let it sit for eight hours. Once the stain is neutralized and the mattress is clean, vacuum any remaining baking soda and allow the mattress to air dry.
In short, yes, a 20-year-old mattress is definitely too old and should be replaced. At that age, it's highly likely that it's filled with a buildup of dust mites, allergens, and potentially mildew or mould. The structural integrity is also likely compromised, leading to sagging and less effective support.
"Regular washing, or about once every one to two weeks, is recommended to maintain cleanliness and a healthy sleep environment," says Harris. Once a week if you don't use a top sheet. Once a month if you do. Once a week if you don't use a top sheet.
Hydrogen Peroxide and Dish Soap: Mix a solution of 1 part hydrogen peroxide and 1 part dish soap. Lightly dampen a clean cloth or sponge with the solution and gently blot the stained area. Rinse the area with a damp cloth to remove any residue, and allow it to dry completely.

This is a normal phenomenon resulting from the oxidation of the foam. This process does not affect the functionality of the mattress, and it is also unavoidable. Generally, the yellowing of the mattress is a result of a natural chemical reaction. It occurs in every type of foam, although in slightly different ways.
Using harsh chemicals such as bleach will damage the foam materials. Instead, use a homemade solution of 1 part mild detergent and 2 parts water shaken in a spray bottle until dissolved. Lightly spray the mixture on the mattress. You only need enough to make the fabric surface lather slightly.
While avoidable with a simple mattress protector, yellow stains are extremely common on unprotected beds. In most cases, they result from sweat, urine, and mattress aging.
