Ithiyori yomandlalo ivavanya ukuba umatrasi ulungile okanye umbi

Ngeminyaka yee-1980, ithiyori entsha-ithiyori ye-mat yadalwa kwaye yaphuhliswa. Ngokutsho kwe-cushion theory, ezi zinto zilandelayo zisetyenziselwa ukuvavanya umgangatho we-mattress.

Oomatrasi abasebenzayo kufuneka babonelele ngobume bendalo obufanelekileyo bokulala abantu, ukuze ingqondo nomzimba ziphumle ngokupheleleyo, ngaloo ndlela kupheliswe ukudinwa kunye nokuqokelela amandla. Umzi-mveliso we-mattress kufuneka ube nokuzinza okulungileyo, ukulungiswa okulungileyo, ubungakanani obufanelekileyo, ubunzima kunye nobukhulu, iimpawu ezintle zokungqubuzana phakathi kwe-cushion kunye ne-cushion cover, imbonakalo enhle, ixabiso elifanelekileyo, ixesha elide kwaye kulula ukuyicoca.

Esona sakhiwo siphambili somandlalo okhululekileyo kufuneka sihambelane nemigaqo yobuchwephesha bomntu. Ukuqina komandlalo kubaluleke kakhulu. I-mattress enzima kakhulu iya kwenza kuphela iintloko zabantu, amahlombe, i-hips, i-hips, i-ankle kunye namanye amalungu adibanisa nombhede, ngelixa amanye amalungu omzimba engazinzanga ngokupheleleyo. Ibangela ubunzima bomzimba ukucinezela imithambo yegazi yendawo, okwenza igazi lingakwazi ukuhamba kakuhle. Umatrasi othambileyo kakhulu unokubonelela ngowona mgangatho wenkxaso uphezulu womzimba, kwaye unokunciphisa uxinzelelo lwasekhaya lomaleko wethishu ecinezelweyo, ukuze ungathinteli ukuhamba kwegazi. Nangona kunjalo, ayinakubonelela ngenkxaso eyaneleyo kwaye inokubangela ukugoba okungafanelekanga kwaye kubangele iintlungu zomzimba. Ukuba umntu udla ngokujika ngexesha lokulala ebusuku, umatrasi ongenankxaso uya kutya amandla amaninzi kwaye uzive ediniwe xa evuka ekuseni.

Ngokuqhelekileyo, i-mattress ekhululekile kufuneka inike inkxaso efanelekileyo kumzimba womntu ngexesha lokulala. Kungakhathaliseki ukuba yeyiphi indawo yokulala umntu alala kuyo, ukugoba kwakhe komqolo ngokusisiseko kuhambelana negophe eliqhelekileyo le-physiological curve. Ke ngoko, umatrasi okhululekileyo kufuneka ube nenqanaba elithile lokunwebeka kunye nokuqina. Ukongeza, intuthuzelo ikwabandakanya ukuhanjiswa kakuhle kwe-thermal, ukuphefumla kunye nobungqina bokufuma.

Ukhuseleko Ukhuseleko loomatrasi lunezalathisi ezininzi, ezifana nempahla yoomatrasi kufuneka ibenelangatye elihle lokulibaziseka; abantu abalele ebhedini ixesha elide abayi kulimaza izicubu ezithambileyo; ukwakheka kweekhemikhali zezinto zomandlalo akufanele kuchaphazele impilo yabantu Linda
