He aha nā ʻano e pono iaʻu e mahalo i ke koho ʻana i ka PU foam？

Ma ka mākeke huʻa PU, ua māhele ʻia i ʻelua ʻano: ʻano lima a me ke ʻano pū. Inā ʻaʻole ʻoe ʻike i ka huʻa PU maikaʻi, e aho e aʻo mai nā ʻano aʻe.

E nānā i ka hopena o ka pū

Inā he ʻano pū PU huʻa, e nānā inā laumania ke kāpili a inā kūpono ka hopena huʻa. ʻO ka maʻamau, ʻaʻole pono ka huʻa e lahilahi loa a mānoanoa paha, a i ʻole e hoʻopilikia ia i ka hopena hoʻopiha.

E hoʻāʻo iā ʻoe iho

Ma mua o ke kūʻai ʻana, hiki iā ʻoe ke pīpī i ka huʻa PU ma luna o ka nūpepa e ʻike ai inā ua hāpai ʻia nā wēlau o ka huʻa. Ke hana ʻia kēia, ua kiʻekiʻe loa ka emi ʻana o ka huʻa. Inā ʻaʻohe warping, ʻo ia hoʻi he maikaʻi ke ʻano o ka huʻa a hiki ke hana paʻa. E hana pū me nā mea hoʻolako ikaika, ʻoi aku ka hilinaʻi, ʻaʻole hiki ke kālele wale i ka noiʻi huʻa PU, akā hāʻawi pū i nā hoʻonā noi huʻa PU i hoʻopilikino ʻia, i hoʻohana nui ʻia i ka ikehu hou, ka pūʻali koa, ka lāʻau lapaʻau, ka mokulele, nā moku, nā mea uila, ke kaʻa, nā mea kani, ka lako mana, ke kaʻaahi wikiwiki a me nā ʻoihana ʻē aʻe.

E nānā i ka ʻaoʻao o ka huʻa

I mea e koho ai i kahi huʻa PU maikaʻi aʻe, ua ʻōlelo ʻia e ʻoki i ka huʻa a nānā. E nānā inā like a maikaʻi ke ʻano o loko. Inā nui nā cell, ʻaʻole maikaʻi ka mānoanoa a ʻaʻole kūpono no ke kūʻai ʻana.
