SPRING MATTRESS'S HARDNESS TESTING-SYNWIN

  Chii chinonzi kupfava nekuoma? Nzira iri nyore yekuyera nayo ndeiyi: Rara nemusana, tambanudza maoko ako kumutsipa, chiuno uye chiuno kusvika pazvidya uye kutambanudza mukati kuti uone kana pane nzvimbo; wotendeukira kune rimwe divi uye shandisa zvakafanana Edza kuona kana pane mukaha pakati pechikamu chakanyura chemuviri curve uye metiresi. Kana zvisina kudaro, zvinoratidza kuti mattress inokodzera mazamu echisikigo emutsipa, kumashure, chiuno, mahudyu nemakumbo emunhu panguva yekurara. Metiresi yakadaro Inogona kunzi yakapfava uye yakaoma. Wese munhu ane zvaanofarira zvakasiyana pakuoma kwemamatiresi. Vamwe vanhu vanofarira kurara pamibhedha yakaoma, asi vamwe vanofarira kurara pamibhedha yakapfava. Metiresi yerudzii iyo metiresi yakanaka? Makore makumi matatu apfuura, muGermany makaita gakava pamusoro pekuti metiresi yakasimba iri nani here kana kuti metiresi yakapfava. Hurukuro iyoyo yakakwezva kutora chikamu kweGerman ergonomics bachelor community uye yakatungamirira kukudzidza kwemaitiro ekurara kwevanhu. Mhedzisiro yechidzidzo ndechekuti kunyangwe metiresi yakanyanya kuomarara kana kuti yakapfava, haina kunaka kune hutano hwevanhu kurara, uye metiresi chaiyo inofanirwa kuve yakakwira elastic metiresi. Kureva kuti, kana simba rinoitwa pamatirasi rakakura, metiresi inofanirwa 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 zvigone kuzorora uye kuwana kuzorora kwakazara. Sezvo musana wemunhu uri muchimiro chisina kudzika S, tsigiro ine kuoma kwakakodzera inodiwa kana wakarara, saka iyo elastic metiresi yakakosha kunyaradzo yemuviri wemunhu uye kunaka kwekurara. Sarudzo yematiresi haifanire kuvimba chete nekunzwa, kupfava kana kusimba kwakanyanya hakuna kukodzera, asi zvichienderana nekusiyana kwehurefu uye uremu. Vanhu vakareruka vanorara pamibhedha yakapfava, kuitira kuti mapendekete nemahudyu zvinyure zvishoma mumatiresi uye chiuno chinotsigirwa zvizere. Vanhu vakaremerwa vanokodzera kurara pamatiresi akasimba. Simba rechitubu rinogona kupa chikamu chimwe nechimwe chemuviri zvakakodzera, kunyanya kana mutsipa uye chiuno zvakatsigirwa zvakanaka. Unogona kureva kureba, uremu uye metiresi kusimba kuenzanisa tafura, zvichava zvakawanda nesayenzi.
