Description of intervention(s) / exposure
In this observational study participants will be asked to complete the self-report questionnaires outlined below. They will be provided with an email link to access Survey Monkey questionnaires for online completion. If unable to access online, printed copies will be provided for manual completion.

Self Report Questionnaire;
1. Self-report percentage allocation sleep postures
2. General Questions; Age, Gender, Sleeping Arrangement: Partner/Solo, Height and Weight (BMI), Highest Education Level (High school, Registered Trade, Undergraduate, Post Graduate), Medications and Comorbidities.
3. 11 point numerical rating scales for bothersomeness, pain, stiffness and quality of sleep.

Medical Outcomes Study 36-Item Short-Form Health Survey
Spine Functional Index (SFI-10)
Neck Disability Index
Rowland Morris Disability Questionnaire
Hospital Anxiety and Depression Scale
Insomnia Severity Index
Pittsburgh Sleep Quality Index

Infrared cameras will be temporarily installed on stands, in the participant's bedroom and activated automatically to record from 8PM to 8AM. Recording will occur for 3 consecutive nights.
The cameras will record posture and later during analysis, time spent in each primary (prone, supine) and intermediate (supported sidelying and 3/4 prone) posture will be calculated. In addition, the number of posture shifts per night and the number of long periods of immobility (no posture shift for 30 minutes) will be calculated.
