As far as we know, the density is one of few most essential factors affecting how a memory foam mattress works. Different brands or mattresses use different density foam. You will find 2.5 – 3lbs/ft low density or 4 lbs medium density foam in cheap mattresses and 5 lbs or denser foam in expensive ones. This post is going to show more details about difference among all three density ranges.

1. The density has much to do with memory foam durability. Generally speaking, high density memory foam mattresses have a longer life and serves 8 years on average, while 4 lbs or less have relatively short longevity, 4 – 5 years on average. But please note a particular mattress may have different performance.

2. High density is more temperature responsive and low density foam is more sensitive to weight than temperature. When a person lays on the mattress, his body temperature starts to warm up memory foam and the area in contact with body becomes softer. So owners will feel sinking into the bed and sleeping in the cloud.

Owners of low density weight responsive memory foam tend to have different feeling and experience on exactly the same bed. A 250 lbs person sink much more than the other weighing 120 lbs. The heavy one will feel soft but his partner won’t receive adequate cushion. For couples who weigh different, a mattress with sufficient height and density allows both to benefit the most.

3. Doctors often recommend memory foam mattress to back pain sufferers. That being said, the functionality of easing back pain has been accepted widely. Low or medium density is good enough to help remove aches but high density performs a little better.

4. Movements transfer reduction is a unique feature of memory foam different from other types. Despite density difference, all memory foam mattresses do well in motion isolation. But thicker or denser foam mattresses are relatively better.

5. Heat retention is the biggest flaw of memory foam mattresses and it received more owner complaints than spring, air and other types. Regardless of density, all have complaints but the denser the more. High density foam tends to have narrow space for air circulation and the retained heat cannot exchange with fresh cool air outside the bed. All brands are focusing on this issue and developed gel infused foam and other technology.

6. In comment or review section, it’s easily to find owners complained about off-gassing issue. Any new products come with a little smell when arrives. Owners notice memory foam mattresses have strong chemical-like smell when unpack it from plastic. That is because they are vacuum sealed and air tight in a box for delivery from the time when they were manufactured. Generally, high density beds have stronger smell so they need longer to dissipate. One thing you have to know the fresh foam smell is harmless completely.

7. Memory foam mattresses mold and map your body shape to provide sufficient support and comfort. However, the body impression doesn’t restore to its original shape when you want to change positions or get out of bed. It’s not spring mattress you owned before and it requires extra effort to move. Weak or disabled persons may not do well with it. Relatively, low density has quicker reaction to movements on the bed and is easier for people to move.

Goodsleep!
