Abstract
This study discussed the spinal alignment and lying comfort for the subjects within different height ranges when lying on zonal spring mattresses by indentation measurement and body pressure distribution measurement. Nine healthy female subjects were instructed to lay on three kinds of zonal spring mattresses. The height ranges of subjects were from 150 to 170 cm. The results indicated that the ratio of back to buttock sinkage of different height subjects laying on mattresses is in the range of 0.6 to 0.8, the distance of waist and back of different height subjects laying on mattresses is 20–30 mm. Height difference on mattress sinkage of three kinds of five zonal spring mattresses has no significant effect. Tall subjects got better pressure distribution on the mattress with more length in back zone and short subjects on the mattress with less length in buttock zone. It’s a matter with height of subjects.
