This is a preliminary single-arm study. The study will last up to 4 weeks including the screening period. Subjects will sleep using the mattress support at home for two consecutive weeks.
Outcome measures will include: AHI derived from HSAT (primary outcome), oxygen desaturation index (ODI), Epworth Sleepiness Scale (ESS) score, Functional Outcomes of Sleep Questionnaire (FOSQ), Visual Analog Scale (VAS) and questionnaire assessments of sleep quality, and actigraphic sleep measures. Subjects will also keep a sleep diary every night for the duration of the study. Subjects will be asked about their bed partners' report on snoring and witnessed apneas.

| Wave 4.3 | Device | The Wave 4.3 mattress support is an insert, placed underneath the user's existing mattress, that when inflated increases the longitudinal incline of the mattress support, increasing in inclination in the direction of the head of the bed. The resulting mattress contours are such that the mattress has a lateral inclination of approximately 15 degrees in the head section and 10 degrees in the torso section. In addition to the features allowing the user to activate and deactivate creation of this Graduated Lateral RotationTM orientation, this device has sensors and monitoring system allowing for remotely monitoring the status of the system, including confirming that the supports are achieving the prescribed support angles, and that the system is working as planned. |

| Apnea-Hypopnea Index Difference Between Two Nights | Apnea-Hypopnea Index derived from Home Sleep Test. The apnea-hypopnea index (AHI) is the combined average number of apneas and hypopneas that occur per hour of sleep between two nights. AHI<5 is indicative of no sleep apnea, AHI 5-15 is indicative of mild sleep apnea, AHI 15-30 is indicative of moderate sleep apnea, AHI>30 is indicative of severe sleep apnea. The minimum AHI is 0, and there is no maximum. A higher score means a worse outcome. Subscales are not used to compute the value. The difference was calculated based on the value at night 1 minus the value at night 2 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants. | 2 nights |

| Oxygen Desaturation Index Difference Between Two Nights | Oxygen Desaturation Index calculated based on the average between two nights measured. Desaturation episodes are generally described as a decrease in the mean oxygen saturation of ≥4% (over the last 120 seconds) that lasts for at least 10 seconds. ODI values can range from 0 to greater than 30. A higher score means a worse outcome. Subscales are not used to compute the value. The difference was calculated based on the value at night 1 minus the value at night 2 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants. |

Inclusion Criteria:
• 18-75 years of age
Willing and able to give informed consent
Able to speak and understand English
Previous sleep study prior to enrollment done based on previous clinical evaluation by the subject's treating physician in the course of usual clinical care:
Using at least a queen-sized mattress when sleeping at home
Patients who meet the above criteria who have been prescribed CPAP or dental device but are non-adherent to treatment will be enrolled in the study. CPAP non-adherence will be defined as average nightly use < 4hrs/night based on a download of the CPAP machine, or self- acknowledged discontinuation or non-regular of CPAP use.
Exclusion Criteria:
• Incapable of giving informed consent
Under the age of 18
Active titration of medication
Pregnancy, lactation (will be screened with urine pregnancy test)
Self-reported Substance abuse (current)
Excessive alcohol consumption
Use of home oxygen
Presence of severe daytime sleepiness defined as an Epworth sleepiness scale score > 16 or a prior history of falling asleep while driving
Presence of cardiac pacemaker or automatic implantable cardioverter-defibrillator (AICD).
Unstable medical problem such as uncontrolled hypertension.
Body Mass Index (BMI) >45 kg/m2
Any other clinically significant condition that, in the opinion of the investigators, might put the subject at risk of harm during the study or might adversely affect the interpretation of the study data.
