Hi, there.Welcome to Shanghai Cozimax Sci-Tech Co., Ltd.

01What’s memory foam?

First designed in the mid-1960s for NASA airplane seats, memory foam is made from a substance called viscoelastic.

It is both highly energy absorbent and soft.

Memory foam molds to the body in response to heat and pressure, evenly distributingbody weight. It then returns to its original 

In addition to protecting against impact, these properties make memory foam very comfortable. After its "virgin flight" for NASA, 

memory foam made a foray into other applications. For example, it was used as cushioning in helmets and shoes. Medicine 

found a use for it in prosthetics and products to prevent pressure ulcers such as seating pads for whom are severely disabled.

Then, memory foam really took off. It's now well known for its use in pillows, mattress toppers, and mattresses, which come in

different densities and depths. 




               

02Is memory foam sensitive to temperature?

Memory foam is temperature-sensitive, so environmental temperatures may affect how it feels. For mattresses and mattress toppers, in particular, very warm and humid weather may make them feel softer, while very cold weather may make them somewhat firmer. If you feel a memory foam mattress or mattress topper is too firm, try removing the conventional mattress pad to allow the memory foam material to be more responsive to your body temperature. If you feel the memory foam mattress or mattress topper is too soft, try adding a conventional mattress pad to make the mattress seem firmer without losing the pressure point relief. You may also try keeping the room slightly cooler. 


03Why does my new memory foam product have an odor?

Memory foam may have a slight odor that remains from the manufacturing process. This odor, often referred to as a“fresh          foam smell”is normal and completely harmless, and will dissipate within a few days. Both memory foam and conventional foam    are used in products you come in contact with every day such as upholstered furniture, vehicles, and office furniture. The “new    car smell”is attributed  to the foamused in the seats. All memory foam materials have this smell when first opene especially        because they have been vacuum  sealed and air tight from the time they were manufactured. The smell is harmless. 


04Can I wash the memory foam products?

No. Memory foam product is not washable, dry in the ventilated area is ok. But you can wash the pillow cover if removable.

05How and when can I get the sample?

We can provide a sample for quality checking first. Sample cost will be refunded after order confirm. It will take about 4~6 days to 

prepare a sample. 

06Can we have our own Logo and company info on the products or package?

Yes. We provide OEM service, products are customized base on clients request. But MOQ required at our side.

09How can I lengthen the life or care to my memory foam product?

When you acquire a new memory foam mattress, you do not want it to develop deep body indentations as this will create an uneven mattress which will lead to uncomfortable sleeping. Ranking’s mattresses are not reversable or flipable. Laying the mattress on a flat surface or good condition foundation will maintain the mattress life span. If you have a Memory Foam Topper, it should be flipped every 2 weeks. 

10What are the differences between the different mattresses Ranking offers?

Good question. Different people have different likes, needs and body types. We suggest that you carefully read all of our mattress descriptions and choose the mattress that best fits your unique needs. They vary in different sizes and thicknesses.
