Kuyera kuoma kwemetiresi

Nzira yekugadzira metiresi yakagadzirwa-yakagadzirwa inonzi moderate hardness? Nzira yakapfava yekuyera ndeye: rara pamusana wako, tambanudza maoko ako kumutsipa, chiuno uye mahudyu kune matatu akajeka mabhende pakati pehudyu, uye ona kana pasina. tendeukira kune rimwe divi uye edza nzira imwe chete kuti uone kana paine mukaha pakati pechikamu checoncave chemuviri curve uye metiresi. Kana pasina gaka, zvinoratidza kuti metiresi yakabatana nemutsipa, musana, chiuno, uye chiuno chemunhu panguva yekurara. Iyo inonyatsoenderana neyakasikwa curve yemakumbo, saka metiresi inogona kunzi ine mwero yakapfava uye yakaoma. Munhu wese ane zvaanoda zvakasiyana pakupfava nekuoma kwematiresi. Vamwe vanhu vanofarira kurara pamubhedha wakaoma, nepo vamwe vanofarira kurara pamubhedha wakapfava. Metiresi yekuomarara ndeipi metiresi yakanaka? Makore makumi matatu apfuura, Germany yakambotanga nhaurirano pamusoro pekuti metiresi yakaoma iri nani here kana kuti metiresi yakapfava. Hurukuro iyoyo yakamutsa kubatanidzwa kweGerman ergonomics bachelor's denderedzwa uye yakatungamira pakudzidza kwekurara kwevanhu. Mhedzisiro yechidzidzo ndechekuti kana metiresi yakanyanya kuomarara kana kuti yakapfava haina kunaka kurara kune hutano, iyo metiresi chaiyo inofanirwa kuve yakakwira-elastic metiresi. Izvi zvinoreva kuti, kana simba rinoshandiswa pamatirasi rakakura, metiresi inofanira kudonha zvakanyanya uye kuburitsa tsigiro yemuviri wemunhu, uye zvinopesana. Izvi zvinodaro nekuti muviri wemunhu icurve, uye chete pane yakakwira-elastic metiresi inogona kutsigirwa muviri wemunhu uye kumashure, kunyanya chiuno chinofanira kuve nerutsigiro rwakasimba, kuitira kuti zvikamu zvese zvemuviri wemunhu zvigadzikane uye kuzorora zvizere. Mametiresi akagadzirwa nekuti musana wemunhu hauna kudzika S-shaped, tsigiro ine kuomarara kwakakodzera inodiwa pawakarara, saka inochinjika metiresi yakakosha kunyaradzo yemuviri wemunhu uye kunaka kwekurara. Sarudzo yematiresi haigone kuve yakavakirwa pamanzwiro ega. Hazvina kukodzera kusarudza mattress yakanyanyisa kana kuti yakaoma, asi zvichienderana nekusiyana kwehurefu uye uremu. Vanhu vakareruka vanorara pamubhedha wakapfava, kuitira kuti mapendekete nemahudyu zvinyure zvishoma mumatiresi, uye chiuno chinotsigirwa zvizere. Huremu hunorema hwakakodzera kurara pamatiresi yakaoma. Simba remuchirimo rinogona kupa tsigiro yakakodzera kunhengo dzese dzemuviri, kunyanya kana mutsipa nechiuno zvakatsigirwa zvakanaka. Iwe unogona kureva tafura yekuenzanisa yehurefu, uremu uye kupfava kwematiresi, ichave yakanyanya sainzi
