Compare Top Memory Foam Mattresses: Zinus Ultima Comfort vs. Signature Sleep Memoir

Memory foam mattresses minimize pressure on the body and provide balanced support. They achieve this by molding to the body in response to heat and pressure, evenly distributing body weight.
Indeed, when you lay on a memory foam mattress, it creates rapidly a personalized and balanced form around your body, supporting your weight evenly, eliminating motion disturbance and relieving pressure focused on your shoulders, hips, and feet. The result can be a unique and unprecedented sleeping experience. The mattress reverts to its original shape once the pressure is gone. Another advantage of memory foam mattresses is being less aware of a bed partner's movements because there are no coiled springs. It is also claimed that these mattresses might be especially helpful for older people, because minimizing extra movement could reduce the number of times they wake up during the night. On the negative side, memory foam can produce an odd smell when first used. To minimize this problem, it is recommended airing out the mattress for at least 24 hours before putting sheets on it. This should dissipate any smell. Finally, note that memory foam mattresses and similar soft materials should not be used in infants' beds, as soft bedding traps can increase the risk of sudden infant death syndrome (SIDS). Memory foam mattresses are usually made of viscoelastic foam and consist mostly of either a 2-layer or 3-layer design:
The top memory foam layer molds to the body shape when it comes into contact with body heat. This helps to support your body along the curves and natural lines of the body, reducing downward pressure and stress on joints. The middle comfort layer relieves further pressure from joints and different body parts. The base layer is made of high density foam so it can support all the weight that's above it. The following pictures show the two 2-layer and 3-layer designs:
This article will compare the Zinus Ultima Comfort and Signature Sleep Memoir memory foam mattresses. These were not just the most popular among Amazon customers at the time this article was written, but they had also received excellent reviews from most Amazon buyers (average rating of 4.5 out of 5 stars for each of the two brands!).
