What Is Memory Foam?
Memory foam is a viscoelastic material originally designed by NASA for shock-absorbent seats. Besides its extraterrestrial applications, memory foam has also been used in shoes, medical prosthetics, and sports helmets.
Today, it is more commonly used as mattress foam for its ability to mold to the body in response to heated pressure. It evenly distributes body weight, and once cooled, will reform to its original shape.
How Long Does Memory Foam Last?
Most experts estimate that memory foam mattresses can last between eight and ten years. This, of course, depends on how well the mattress is cared for. Encasing your mattress in a liquid-resistant protector is a great way to help it last, and keep it stain-free.
Is Memory Foam Good for Back Pain?
Yes. Memory foam’s ability to conform to your body shape helps improve spinal alignment and easily dissipates pressure to relieve aches and pains throughout the body.
What Are the Pros and Cons of Memory Foam?
Besides its ability to provide pain relief, memory foam has the ability to isolate transfers of motion. So, it is a great choice for couples, especially ones with different sleep schedules. Memory foam is perfect for someone who is a light sleeper and has a partner that gets up frequently at night or wakes up earlier than him or her.
For some, the heat retention of a memory foam mattress can be uncomfortable, especially in warm weather. But most will combat this issue by adjusting the thermostat or using a thinner blanket. Also, some new memory foam mattresses can emit a chemical, which can be unpleasant but is not physically harmful.
