Hlobo luni lomkhiqizi we-mattress okufanele silale

Hlobo luni lomkhiqizi wombhede wombhede okufanele silale? . Ukuqina khumbula akunzima ukukhumbula isimiso umatilasi deformation, futhi uthambile deformation akuyona enkulu kakhulu. Kungenzeka futhi lapho ukhetha umatilasi, oqhutshwa ngokulandela isimiso: umatilasi awugqinsi ka-cm, ingcindezi yesandla eshona phansi ifanele; Umatilasi owugqinsi ongu-Cm, u-cm ongenalutho oluncane oluthambile oluqinile olumaphakathi, njalo njalo. 。 Futhi idigri ilele ngomhlane wakho ngesandla sikamatilasi ofanelekile angagcina ukunwebeka kwemvelo komgogodla, nehlombe, ukhalo kanye ne-hip joint ngokuphelele, kungashiyi zikhala. Lala phansi kumatilasi, isandla siye entanyeni, okhalweni nesinqe sehle siye ethangeni phakathi kwalokhu kugoba okuthathu okusobala sivundlile, bheka sinegebe; Ukujikela ohlangothini olulodwa, izame ngendlela efanayo ijika izingxenye zomzimba futhi ingabe kukhona igebe phakathi komatilasi. Uma isandla singakwazi ukungena kalula ezikhaleni, kubonisa ukuthi umbhede unzima kakhulu. Uma entendeni yesandla sakho eduze igebe, kubonisa ukuthi umatilasi nabantu ngesikhathi ubuthongo intamo, emuva, okhalweni, hip nomlenze ijika yemvelo kufanelekile. 。 Ubukhulu be-spring umatilasi ~ cm ubukhulu umatilasi awukho mkhulu, kodwa uhlotshaniswa namandla ayo asekelayo, ikakhulukazi umatilasi wasentwasahlobo, uma ubude be-springful njalo, ukuqina kwezingubo zokulala phansi, ngokushintshanisa amandla okusekela akulungile. Ubukhulu bomatilasi wasentwasahlobo obufanele bufika ku-cm. Lapho intwasahlobo ngenxa yezinkinga zekhwalithi zenzeka ukuguqulwa, amandla asekelayo azothonya, ukushintsha ngesikhathi. Umatilasi onesikhathi eside nawo kufanele ushintshwe. Njengoba manje sebenzisa morer entwasahlobo umatilasi, uma isikhathi eside, entwasahlobo ulahlekelwa nokunwebeka, retainer force izothinteka, bese sebenzisa, akusizi ukulondoloza umzimba womuntu ukugoba evamile bokuphila komgogodla.
