Memory Foam Specifications

The TruCell visco elastic memory foam has a 4.0 lb density and an ILD of 11. In tests more people preferred this 4.0 lb TruCell memory foam for two main reasons. The first was the issue of heat, or lack of heat. The memory foam samples that were more dense proved to hold more heat than the 4.0 lb. Also, it didn't leave too much of the "crater" dip that many memory foams are known and disliked for. It has the perfect amount of support and contouring, but still allowing you to turn and adjust in bed comfortably.

Support Foam Specifications

Base foam or support foam is equally as important to the comfort of the mattress as the memory foam is. The density of the base foam will determine how long the mattress will last, and the firmness will determine the amount of support it gives your body. The M-Grade base support foam has a density of 2.0 lb and an ILD of 41. Typically, average mattresses have support foams with densities ranging from 1.5 lb to 1.8 lb, 1.8 lb being for nicer mattresses. It's rare to find mattresses with base foams more dense (or better quality) than this. That's why we've decided to provide this quality. And for this reason, we can offer a 20 year warranty.

Disipates Heat

The most common complaint with memory foam mattresses in general is that it can sometimes make a person feel warmer. Memory foam is very dense foam, making it harder for heat to escape. The more dense the foam, the less air flow for heat to escape. To overcome this problem, we uses TruCell memory foam, which has an open-cell structure. The open-cell structure allows heat to escape and air to flow around the body, creating a more comfortable sleeping environment.

Odorless

Another common complaint with most memory foam mattresses is the odor. The chemicals used in all foam products produce an odor. However, with more dense foams, like memory foam, because there is a higher concentration of these chemicals the odor is typically stronger. The TruCell memory foam is a "virtually odorless" visco foam because of the open-cell structure, allowing it to breath much easier. If there does seem to be a little bit of an odor to the mattress, it may take as much as a week to disappear.

Overnight Mattress mattresses are made in the USA with strict standards and quality controls. With stat-of-the-art equipment, Overnight Mattress foams are screened for odor & density to create an inviting, supportive sleep environment that will feel just as good in ten years as it does the day you receive it."

Well, hey, they convinced me it was worth a try! The main thing is the free shipping both ways with 120 days to try it - NO ONE ELSE has a sleep guarantee like that, as far as I know. Even Flobeds makes you pay the return shipping back to them!
