Buying the appropriate mattress and bed base can be a stressful task for new bed buyers. Bed systems vary greatly in price, quality, aesthetic appearance, and size. Making the right purchase is extremely important to everyday life, as a bed “allows physical recuperation during sleep by providing proper body support” (Verhaert et al., 2012). With sleep disorders becoming an ever more present problem in society, maximizing body recovery during sleep has become increasingly important (Desouzart & Filgueiras, 2015). People recover the most when their spine is in its natural shape, “allowing muscle relaxation and rehydration of the intervertebral discs” (Verhaert et al., 2012). Unfortunately, because of individual differences in body dimensions and the dispersal of body weight, a single bed is unlikely to work for every individual.

Shown below are two images of pressure mappings of a person while lying on their side on two different mattresses. The dark blue color mean that their body does not feel much pressure, while the red and orange colors mean that this is an area of high pressure (Vaughn Mccall, Boggs, & Letton, 2011). It is clear from this image that when a mattress is appropriate for a person, their body does not feel as much strain and they can therefore sleep better.

The above image shows pressure mapping in the fetal position on a mattress that is not appropriate for the person’s body.

I propose that mattress companies begin to state the ideal body measurements and weight distribution for their mattress. I also believe that buying locations should take anthropometric measures of potential buyers to help guide them to the perfect mattress. Verhaert and colleagues found that they were able to “individually assess quality of support provided by a particular mattress–bed base combination” in their 2012 study. This could be an expensive system to implement today, but in the future I see it being much more feasible as the price of 3-D scanners decreases. In the mean time, basic hand measurements would be an improvement on the current system of having a buyer simply lay in a bed and test it.

  1. I think it’s really interesting that you provided an analysis of something that I don’t think a lot of people consider the ergonomics perspective of. For me, I often associate ergonomics with improvements in environments such as the workplace, but it is also important to consider this perspective in other environments. The point about pricing would probably pose an obstacle, but I believe that society should begin to invest in important things such as this because it will provide positive outcomes in the future.

  2. I had never really thought about mattresses from an ergonomics perspective, so I love that you did this. I was especially interested in the pressure mapping diagram you included. Its really crazy to think about how sleeping, which is supposed to be relaxing and restful, puts stress on certain parts of your body. This is definitely important to consider when buying a new mattress!

  3. I think it is very interesting to include mattresses with ergonomics and human factors, since they, along with sleep, are so important to people. Combining ergonomics would definitely improve people’s living quality. It is also nice that you include the pricing in the blog as customers would be very interested in this part of the mattresses. If they can be created and sold cheaper, these mattresses would totally be popular.
