Scientifically proven sleep study

Air adjustable number beds actually improve overall sleep quality

Based on a 7 week sleep study

Does a number bed offer the best night's sleep? Looking over the Personal Comfort website it appears that a number bed is the best mattress you can buy. Well you may be asking yourself is there any scientific proof to back up the claims. Yes there is. We decided to have our air adjustable beds put to the test to see if in fact they truly do help alleviate chronic low back pain.

Here are the results:

  • 90.0% of sleepers had improvement of sleep and pain
  • 88.9% of sleepers had a reduction in back pain
  • 85.2% of sleepers had a better night's sleep

After the sleep study was complete we asked how willing the participants would be in purchasing one of these beds after the trial and we found that 81.5% of the participants want to buy a number bed.

Scientific conclusions

Use of a number bed sleep system results in a reduction in morning pain experienced by the victims of chronic low back pain. More than just a numeric result detectable through statistics, 31% of study subjects reported an amount of pain relief that could be expected from the use of analgesics. Victims of chronic low back pain should consider an air adjustable firmness sleep system, as it offers a substantial possibility of significant pain relief.

Morning discomfort in the group with sleep adversely affected by chronic low back pain was also substantially reduced. Even pain prior to lights out, and by implication possibly during the day as well was notably reduced.

Physiological sleep measures, both by actigraphy as well as polysomnography, showed disturbances on the subject’s original mattress. Parameters showed trends in improvement, most notably sleep efficiency and especially arousals. The lack of statistically significant change may be a reflection of a variety of issues: unidentified elements unique to this study populations, pain levels, a greater length of time on the therapeutic mattress being needed before improvement could be measured, or that the measures themselves are not sensitive enough to measure the aspects of sleep responsible for the robust subjective changes. Pain shows substantial fluctuation across the night in most individuals. Low level pain may be significant enough to affect sleep depth and produce fatigue without necessarily producing striking alterations in the major features of sleep architecture.

The general outcomes measures, FOSQ and SF-36, both showed significant disturbances, and were improved by the bed system. Again, the lack statically significant changes may be a reflection of the same issues described above.

The global measures are compatible with measured experimental improvements, supporting the beneficial effects of the number bed sleep system.

Overall, the data collected certainly supports the conclusion that individuals with chronic low back pain should strongly consider an air adjustable firmness sleep system as an important aspect of the management of their pain.
