NASA Memory Foam Matress - Ulwazi oluSiseko

googletag. bonisa(\"div-ad-articleLeader\");
I-NASA yavelisa umatrasi obizwa ngokuba yi-memory foam mattress ngo-1970s.
Ukusukela ngoko, i-foam encangathi, ngamanye amaxesha eyaziwa ngokuba yi-NASA foam mattress, isetyenziswe okokuqala kwiindawo zonyango ukunqanda uxinzelelo olubuhlungu.
Umatrasi usetyenziselwa iibhedi ezineebhedi kunye nezitulo ezinamavili.
I-NASA foam umatrasi ilinganiswa ngokuphambuka komthwalo womgibe woxinzelelo (ILD).
Ngokusisiseko, i-ILD ngumlinganiselo wobunzima bomandlalo.
Ngamanye amazwi, ngumlinganiselo osemgangathweni wokuba unzulu kangakanani kumatrasi ukuba uhleli kuwo.
I-ILD phakathi kwe-10 kunye ne-11 ithathwa njengethambileyo.
I-ILD phakathi kweminyaka eyi-12 kunye ne-16 ithathwa njengeqinile kwaye i-ILD phakathi kweminyaka eyi-16 kunye ne-20 ithathwa njengeqinile.
Sonke sibonile iintengiso zogwebu lwenkumbulo ezibonisa indlela eyenziwe ngayo nexhaswa ngayo.
Kodwa kukho izinto ezininzi ekufuneka ziqwalaselwe kumthengi oqhelekileyo.
Ziziphi iintlobo ezahlukeneyo, zeziphi iingenelo kunye nokungalunganga, ngokuqinisekileyo, akukhona nje ukuba kuqwalaselwa kangakanani.
Ubuninzi be-foam bubalulekile.
Uxinaniso logwebu lukwiiyunithi nge-cubic foot pound.
Iimatrasi ezinobunzima obungaphantsi kwe-3 pounds ayikwazi ukunika inkxaso eyaneleyo.
I-foam eqinile yomelele kwaye ifaneleke ngakumbi inkxaso.
Igwebu elishinyeneyo nalo liyatshisa.
Ixabiso lomandlalo wenkumbulo encangathi lisuka kwi-300 yeedola ukuya kwi-1000 yeedola.
Umahluko wexabiso uxhomekeke ikakhulu kubungakanani bomandlalo.
Umgangatho we-foam nawo uya kuchaphazela ixabiso.
Oomatrasi bememory foam badla ngokubiza ngaphezulu koomatrasi basentwasahlobo.
I-foam yememori yahlukile kwi-foam eqhelekileyo.
Xa ulala phezu kwegwebu elincangathi, ubushushu obuphuma emzimbeni buya kukuvumela ukuba buhambe.
Igwebu liya kwenza i-contour emzimbeni wakho.
Xa uvuka, kuya kubakho isibonda kwisimo somzimba wakho.
Emva kwexesha elithile, i-foam ibuyela kwimeko yayo yangaphambili xa ingaphazanyiswa.
Inzuzo ephambili yomandlalo we-foam yememori kukuba ubunzima bakho busasazwa ngokulinganayo ngegwebu.
Akukho nto inokwenzeka yoxinzelelo kwi-mattress yasentwasahlobo.
Yiyo loo nto oomatrasi be-NASA bezama kwindawo yonyango kwizigulana ezilele ebhedini.
Enye ingongoma ye-foam yememori kukuba ukunyakaza akulula ukudlulisa.
Oku kuthetha ukuba ukuba wabelana ngebhedi kunye neqabane lakho, izenzo zeqabane lakho aziyi kudluliselwa kuwe, okukhokelela kubuthongo obunoxolo.
Eyona ngxaki inkulu yalo matrasi kukuba ifunxa ubushushu obuninzi kunomandlalo oqhelekileyo.
Nangona oku kunokuba luncedo ebusika, kuyingozi ehlotyeni.
Umatrasi omtsha uhlala unevumba lekhemikhali kwaye unokufuna ukuba womiswe phambi kokuba usetyenziswe.
Ukongeza, nikela ingqalelo kumatrasi ngexabiso eliphantsi.
Ezi zidla ngokuba ziimveliso eziphantsi.
