Why is higher density 5.3lb Memory Foam better?
Density is the key to a finer quality mattress and a healthy night’s rest. Lower density Visco-Elastic Memory Foam such as 3lb or 4lb density cannot provide the life improving health benefits that only true 5.3lb density Memory Foam can provide. Lower quality 3lb or 4lb Visco-Elastic Memory Foam are not as heat or weight sensitive to your body and resurface too quickly. Resurfacing too quickly actually causes pressure against your body which creates painful pressure points that cause you to toss and turn at night. Lower density foam also fails quickly, usually within only 3 years.
