Our CNET Sleep editors have examined extra beds than the common sleeper — round 300 totally different ones, in reality — and have devoted a whole lot of hours to the craft. We take satisfaction in our mattress testing methodology.

Firmness and really feel

Once we begin mattress testing, we first decide the firmness and really feel of the mattress. Firmness is just how exhausting or comfortable a mattress is. Now we have a number of staff members check and charge every mattress to get probably the most well-rounded image of how a mattress performs in these classes.

The texture of the mattress describes how the mattress reacts. Is it sluggish responding like conventional reminiscence foam? Does it snap again like latex foam? This can translate to the way it will really feel rolling round on the mattress at evening. 

We additionally check firmness objectively utilizing our proprietary CNET machine, the Mattress Smasher 9000. This machine presses into the center of a mattress, and our corresponding software program measures firmness on a scale of 1 to 10, with 1 being the softest and 10 being the firmest. Whereas we additionally check every mattress personally for perceived firmness and really feel, we are able to help our opinions with the info from the Mattress Smasher.

Mattress efficiency

Edge help is how robust the perimeter of the mattress is. The check for that is easy: we sit and lie on the sting to see if it offers approach underneath strain.

When assessing temperature, we look at the supplies and development of the mattress. Supplies like latex and gel reminiscence foam can hold a mattress from retaining physique warmth.
