The primary study objective is to determine whether mattress firmness affects pain in patients with chronic low-back pain. We hypothesize that mattresses that differ in their firmness and support should have a varying effect on low-back pain patients' level of pain and pain-related disability. We also seek to test the hypothesis that the optimal mattress might vary from person to person.
In this regard, we will test:
1. Whether there is a single mattress that is superior to the others in terms of reducing low-back pain and pain related disability.
2. Whether the optimal mattress for reducing pain varies in the observed population.
Few treatments are effective for chronic low-back pain, a disorder that causes marked social costs in developed countries. A "comfortable" mattress is commonly assumed to play an essential role, both on a preventive and on a therapeutic basis on chronic low-back pain. However, evidence supporting the beneficial effects of different levels of mattress support on pain is lacking.
The primary study objective is to determine whether mattress firmness affects pain in patients with chronic low-back pain. We hypothesize that mattresses that differ in their firmness and support should have a varying effects on LBP patients' level of pain and pain-related disability. We also seek to test the hypothesis that the optimal mattress might vary from person to person. In this regard, we will test:
1. whether there is a single mattress that is superior to the others in terms of reducing low-back pain and pain-related disability and
2. whether the optimal mattress for reducing pain varies in the observed population.
The secondary objectives are:
1. to determine whether there is a relationship between mattress firmness and sleep in this population;
2. to determine whether there is a relationship between pain and sleep in this population;
3. to determine whether key sleep variables (subjective or objective) are mediating or moderating factors of the relationship between mattress and level of low-back pain (LBP) and disability;
4. to determine if different sleep surfaces have differential effects on measures of daily function among patients with chronic LBP;
5. to evaluate if Kingsdown's proprietary algorithm for selecting optimal mattress "fits" with the subject's best mattress for reducing pain and improving sleep and measures of daytime functioning;
6. to conduct exploratory regression analyses using variables included in the proprietary algorithm and other demographics and measures of physical characteristics to predict the optimal "fit" mattress (i.e., the mattress associated with lowest morning pain ratings, best sleep measures and optimal levels of daytime function);
7. to determine if different sleep surfaces have differential effects on measures of partner sleep disturbance;
8. to determine if there is a relationship between partner pain level and partner sleep disturbances.

Pain associated with OBSTETRIC LABOR in CHILDBIRTH. It is caused primarily by UTERINE CONTRACTION as well as pressure on the CERVIX; BLADDER; and the GASTROINTESTINAL TRACT. Labor pain mostly occurs in the ABDOMEN; the GROIN; and the BACK.

Inflammation of the SACROILIAC JOINT. It is characterized by lower back pain, especially upon walking, fever, UVEITIS; PSORIASIS; and decreased range of motion.
