While not an ideal solution, mattress toppers are a cost effective way of either extending the life span of your mattress or upping the overall level of comfort. As we discussed before, a topper is limiting in that it only allows you to utilize one surface. However, there have been some very recent scientific research that suggests there exists the perfect mattress topper.

One Topper To Rule Them All

A very recent 2018 study, published in the peer review journal Plos One, examined the differences created when using both a high rebound mattress topper and a low rebound mattress topper. You would expect that like other facets of sleep, there is some discretion as far as what product suits you best.

However, this study found that the high rebound mattress topper offered advantages that the low rebound mattress topper could not. The specific material used for the high rebound topper is polyethylene resin.

The low rebound material it is compared to is one that most are familiar with: memory foam.  Remember that this study is limited in scope, but that the information is still very relevant to a few common sleep problems people face.  You will be especially interested if you are one to wake up frequently through the night because you can’t seem to stay cool.

High Rebound vs. Low Rebound

Various evaluations of sleep were documented on about thirty subjects split up into two groups. The first group of 10 young adult males reportedly fell asleep faster with the high rebound topper as opposed to the low rebound topper.

There was a large discrepancy between the body temperature of those using a high rebound and low rebound topper. The high rebound mattress topper resulted in a significant lowering of body temperature. REM latency (the time it takes to get to REM sleep) was also found to be shorter with the high rebound topper as well.

They measured the EEG delta power, which is associated with deep sleep levels, of participants during sleep. The result was finding that participants using the high rebound topper spent more time in the deeper stages of sleep.

They found that the same improvements were not visible in the older participants of the study in the areas of core temperature. However, the older participants did see an increase in EEG delta power during the first half of sleep. This suggests that the high rebound mattress topper offers benefits regardless of age in comparison to a lower rebound mattress topper.

No Contest

The high rebound mattress topper made of polyethylene resin performed better in pretty much every way, although not as significant in every area statistically, than the low rebound mattress topper made of memory foam.  Young participants saw improvements in falling asleep, regulating body temperature during sleep, and getting into deeper stages of sleep for longer amounts of time.

Older participants did not see quite the same improvements in core temperature reduction, but overall spent more time in the deeper stages of sleep than if they were using the low rebound topper.  It is worth noting that this is a relatively small sample size for a study like this, but this remains a positive sign for recent developments in mattress and mattress topper designs.

There was no significant increase in REM sleep noted in the study, but that does not necessarily diminish the improvements offered by the high rebound topper.  Memory foam and other similar products have been marketed as the best upcoming mattress/mattress topper innovations available for quite awhile.  It appears that the times could be changing once again as we move towards incorporating new materials.
