1. What is Memory Foam?

Memory foam was originally developed in 1966 under contract for NASA to provide relief for astronauts undergoing the extreme physical stress of “G-Forces.” The material that was invented, visco-elastic polyurethane foam – responds to your body’s heat and gently cradles you, relieving pressure points and improving circulation.

2. What is “density” and how does it affect the comfort of memory foam?

Density is the weight of the memory foam measured in cubic feet. In the past density was important in assessing the quality of memory foam. Today, density is not the only factor that determines comfort. Technological breakthroughs have allowed Sleep Innovations to produce “open cell” products. These are the best performing products on the market – as the open cell structure, not the density, determines quality and comfort.

3.Is 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.

4. is there have cell hole on the foam ?

Accoring to different customize materials, there may have some cell holes on the side surface, but we will try to avoid it.

5. Hardness can be customizes ?

We accept your customized hardness for the foam.

6. does the foam have smell ?

The smell of the foam can disapear in 2-3 days after lay out.

7.Will memory foam make me hot?

Sleep Innovations’ memory foam is made with the latest manufacturing technology, so all of our memory foam products have “open cells.” Open cells are designed to encourage air flow. Open cells dissipate the heat released by your body and head during sleep. Unlike the memory foam products of years ago (which had tighter, closed cells that did retain heat), today’s Sleep Innovations products are temperature neutral or even specifically designed to feel cool to the touch.

8.Is all memory foam fire retardant?

All memory foam meets the standard of California Bureau of Home Furnishing Technical Bulletin (TB) 117 which is the highest standard.

9.Why 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 foam used in the seats. All memory foam materials have this smell when first opened – especially because they have been vacuum sealed and air tight from the time they were manufactured.
