ʻO ka ʻokoʻa ma waena o ka pu pale polyurethane a me ka hao vibrating paku loaʻa i ka hapa nui nā kikoʻī. ʻoi aku ka maikaʻi o ka lawe ʻana o ka pale polyurethane ma mua o ka pale metala maʻamau. Ma waho aʻe o ka palupalu i'ōleloʻia ma luna nei, hiki ke hoʻohanaʻia me ka mea Me ka liʻiliʻi liʻiliʻi o ka hopena, hiki ke laweʻia nā mea hou aku. ʻO ka ikaika tensile kiʻekiʻe, no ka mea, ʻo ka mea o ka pu polyurethane pale ka polyurethane, nona ka palupalu a me ka ikaika stretchable. ʻAʻole hiki ke hoʻopaʻa ʻia ka metala, no ka mea he palupalu ka polyurethane, no laila hiki ke pale i ka hopena. Hana i kahi cushion maʻalahi, ʻo ia ka mea e ikaika ai ka polyurethane.

E like me nā koi o ka mea kūʻai aku, hiki ke hoʻololi i ke kala o ka pale polyurethane pu, e like me ka ʻalani, ʻulaʻula, uliuli, a me nā mea ʻē aʻe, ʻaʻole wale nā ​​hiʻohiʻona brand, akā ʻoi aku ka nani a me ka nani.

E pili ana i ka pilikia o ka ikaika a me ka walaʻau, ma muli o kāna mea polyurethane kūikawā, i hoʻohālikelike ʻia me ka metala, e liʻiliʻi ka leo kūlohelohe me ka ʻole o ka ikaika kiʻekiʻe, a ʻoi aku ka palupalu o ka polyurethane i kekahi ʻano i hoʻohālikelike ʻia me ka metala. ʻAe, no kekahi mau mea wai, hiki ke hoʻomaikaʻi ʻia ka maikaʻi o ka wehe ʻana. I loko o nā mea kānana maoli, ua like ia me nā huahana sieving metala, e like me nā papa maloʻo a me ka pulu o ka ʻaila, a hiki ke hoʻohana ʻia i ka ʻoihana dehydration.
