Is the sofa stuffed with Down pieces?
I. high elasticity sponge (with hard shells and soft high shells)Two, soft sponge (plus hard sponge)Three, clip down cushionIts hard type is the kind of hard to sit up, it is recommended that Louzhu do soft, you can, this is the most common.As far as I know, the middle and high-grade series of sofas are soft, with down and high shells.Hard to use except for special needs.If it is a low price sofa, you need the landlord to see it.
Down sofa is a new product, made of sofa core with it. It is comfortable to look fluffy and will not be aging as long as pure sponge. Another advantage is that it is not easy to get static
When we choose the sofa, we prefer the appearance of the sofa, but what material is the inside padding of the sofa, we hardly care about it or not understand it. Sofa usually uses the following three kinds of material for internal filling.Flexible polyurethane foam (commonly known as sponge) used for sofa filling sponge, mainly divided into three categories: conventional sponge is a regular polyether and TDI as the main body of the sponge. The utility model has the advantages of good resilience, softness and breathability; the high resilience sponge is a sponge generated by active phosphorus accumulating and TDI as the main body, and has the advantages of excellent mechanical property and good elasticity. The utility model has the advantages of large compression load, good combustion resistance and good air permeability; the irregular hole sponge is an inner hole with different sizes of natural algae similar to a sponge, and is characterized by good elasticity, excellent cushioning property when compressed and rebound.Two. Down filling: down to do sofa filling, comfortable sitting, long-term use of small deformation, drawback is slow rebound, high cost. Generally used in conjunction with the sponge in the advanced sofa, or suitable for cushion use.Three. Artificial silk wadding: artificial cotton made sofa padding, soft excellent, comfortable sitting, but poor mechanical performance, compression load is small, only cushion. Sofa filling point of choice: depending on the type of filler, there is a big difference in the use.
In general, sofa cushion filling should be 30 kg / m3 high rebound sponge is appropriate, in the form of most of the sponge filling mode is the best form of 30 kg / m3 high rebound sponge and sponge down with chaos or artificial cotton with increasing comfort and the use of superposition life. When choosing, ask the type of filling. If the filler is a sponge, you should know the density of the sponge used, feel the cushion effect of the cushion with gravity, and sit on the comfort of the feeling of sitting and so on.General use of sponge cushion, national standard 25KG/M3, international standard 35KG/M3. The bottom surface of the structure, the structure of high elastic bandage snake spring structure is superior, inferior quality good bandage bandage structure, Aris sofa cushion is used ecotype high density polyurethane foam, non Freon (a kind of harmful substances will damage the atmosphere) or other diffusion agent; sofa using a molding of polyurethane, 40KG per cubic meter more than the international standard (international standard is more than 35KG per cubic meter), after a long time after compression can still rebound quickly, restore, deformation, collapse.
