其實梳化係得棉, 彈簧包 or wrapping, 木架同 cover (布, leather, pvc/pu, leather air ... etc)再加彈較支架如有
我見過幾個sofa manufacturing site, handle過太多出口sofa complaint ...
基本上最大嘅price difference係响cover度
i.e. foam density can't reflect on price
and the life time quite depends on the foam
personally i only buy cheap version sofa and change every 2 year as
- foam deform after period of time, no matter how much you pay for it!!
- Wooden flame easy get mould after wet weather in HK...
Also, I decided not to buy the brand mention above from other JM as I visited 01999's factory before (01999 is their stock number)
