What is Memory Foam?

Memory foam, first called temper foam, was developed in 1966 to absorb shock and improve comfort in NASA’s airplane seats.[1] This discovery led to an even greater breakthrough here on Earth; however, memory foam products began circulating on the market. Memory foam is also known as viscoelastic polyurethane foam. It undergoes the same process as high-density foam but has a higher thickness and viscosity with added chemicals. Memory foam’s most remarkable characteristic is that it holds an impression on the user, activated by one’s body heat. This has proven useful for sleeping optimally at night in the form of mattresses and pillows, in-shoe orthotics, and unique recliner chairs. In recent years, open-cell and gel-infused foams have been made to improve airflow.

Why You Should Want a Memory Foam Mattress

Haven’t you ever wished you could sink into your mattress? With memory foam, one does. Many people find memory foam comfortable, which can help them sleep well. Hence, putting a box spring for memory foam mattresses will increase the durability of your mattress and get an elevated platform for a low-rise bed. A supportive mattress can help keep your spine in a comfortable position. A memory foam mattress can offer a soft, contouring feel. Some people with pain conditions find memory foam comfortable, but it doesn’t treat any condition. In studies, medium-firm mattresses tended to work best for comfort and sleep quality.[2] If pain keeps you awake, see a doctor.[3]

Features that Constitute Good Memory Foam Mattresses

Here are the top 5 features you can look out for when doing memory foam mattress shopping. This is how you can tell you struck a bargain:
  1. Cooling Gel Infused – If the memory foam mattress is cooling gel-infused, then you know it has additional components in it that absorb heat, allowing for a cooler sleeping experience. These may suit people who tend to sleep hot.
  2. Open Cell Technology – This means the memory foam has micro ventilation or holes from which the hot air generated can escape. This is essential, or the mattress may get too hot at night.
  3. Pressure Point Relief Design – If the design is contoured or raised in any way, this is usually not a bad thing. A contoured or zoned design aims to spread out pressure along your back, which some people find more comfortable. It is not a remedy for insomnia; if you often can’t sleep, talk to a doctor.[4]
  4. Multi-layered Foam Product – Different-density foams with various functions layered underneath a layer of memory foam make for thicker, more comfortable mattresses. These are likely pricey, so grab them if you find a cheap one.
  5. Height – the thicker the memory foam mattress, the more room you have to sink in. Try to go closer to the 14-inch side rather than the 8-inch side, especially if you are a side sleeper.
