The optimal distance between bed slats depends on the type and needs of the mattress. For independent spring mattresses, the bed plate spacing usually needs to be less than 4cm to meet the support needs of most independent spring mattresses and avoid the impact of deformation on the mattress spring. For ordinary mattresses, the bed space parameter standards are mostly about 4cm or 5cm, although the bed space only needs to be <5cm, the bed has a basic guarantee, it is qualified.

If the distance between the bed slats is zero, this can cause the mattress to not be properly placed or supported, which can affect the use experience. In this case, consider adjusting the distance between the bed slats to meet the optimal distance recommended above. If adjustments cannot be made, you may need to consider changing the mattress or bed board design to ensure that the mattress will be placed correctly and supported properly.
