Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Scientific literature refutes the idea that sleeping on the floor improves sleep quality, showing instead that supportive mattresses (such as medium-firm designs) promote better spinal alignment, comfort, and restorative rest.

The analysis

The claim that sleeping on the floor improves sleep quality is directly contradicted by sleep biomechanics and orthopedic research, which demonstrate that supportive mattresses (particularly medium-firm ones) optimize spinal alignment and reduce discomfort. Studies comparing rigid surfaces to mattresses show that specialized support surfaces are ergonomically superior for human sleep.

An MRI study comparing a mattress to a rigid surface found that using a mattress results in significant changes in lumbar alignment, indicating that flat rigid surfaces are less ergonomically suited for sleep.
