What Is Memory Foam?

Memory foam is among the best mattresses on the market today. It was a polyurethane foam produced with chemical additives to provide viscoelastic properties. 

Commonly, memory foam comes with petrochemicals offering its signature contouring feel. However, some manufacturers replace parts of petrochemicals with plant-based oils, making them more eco-friendly. 

Memory foam compresses and stretches under pressure and heat to mold around objects pressing to the surface. So, it can conform to the curves of your body while sleeping on it. 

You can feel high contouring as you stay longer in one position on the memory foam mattress. It can return to its original shape if you move as you sleep.

Then, the mattress returns to its original shape if you get out of it. However, you should remember to replace your mattress sooner or later based on its lifespan. 

You should also look out for warnings that your mattress affects your sleep quality negatively. The longevity of your memory foam mattress can also depend on several factors.
