Key result
Custom multi-layer mattress linked to lower lumbar back muscle activity versus standard mattress in young adults.
Why the study?
The impact of different mattresses on lumbar muscle activity and autonomic nervous system function was unclear.
Does a custom-developed mattress improve lumbar muscle activity and autonomic function compared to a common market mattress in healthy subjects?

A custom-developed mattress may reduce lumbar muscle activity and promote parasympathetic dominance compared to standard mattresses, suggesting potential benefits for back pain and stress management.
Custom mattress linked to lower lumbar activity and parasympathetic shift in healthy adults; leaves open clinical benefits for back pain or sleep quality.
To clarify the impact of different mattresses on motor and neurological functions, lumbar muscle activity and autonomic functions were compared in 16 healthy subjects lying on two mattresses: a common market type (Mattress A) and our custom-developed one (Mattress B). Surface electromyography of the dorsal lumbar muscles and an autonomic function were recorded in 16 healthy subjects in the supine position on two types of mattresses: one generally available on the market (Mattress A) and another developed by our team (Mattress B). Results showed significantly lower lumbar muscle activity and a trend towards parasympathetic dominance on Mattress B. However, the study didn't account for mechanical effects, personal preferences, or body size. The results of this study suggest that mattresses can affect lumbar muscle activity and autonomic function. Further research may help manage back pain and stress related to bedding.

Daikuya et al. (2024) conducted a cross-sectional in Healthy (n=16). Custom-developed multi-layer mattress (Mattress B) vs. Commercially available mattress (Mattress A) was evaluated on Lumbar back muscle activity (%IEMG) (p=<0.001). Lying on a custom-developed multi-layer mattress significantly reduced lumbar back muscle activity compared to a standard mattress in healthy young adults.
