Shopping skills of folding sofa bed
1, suitable size
The folding sofa bed should be used for both sitting and lying, so it must be the right size. Generally speaking, the height of the seat surface is preferably between 35 and 42 cm, the depth of the seat is preferably between 48 and 55 cm, and the inclination of the backrest is preferably between 100- 108 degrees. This is in line with the principle of ergonomics, otherwise it is not conducive to the relaxation of human muscles, and long-term use is easy to cause physical pain.
2. A solid framework
Most folding sofa bed frames are made of hardwood or metal brackets. When choosing, you can shake the sofa with your hands and feel the firmness of the frame. And you can also uncover the bottom cloth under the seat and take a closer look. It is made of smooth and hard miscellaneous wood without decay, moth-eaten, scars, bark and wood hairs. The joints between materials are not nailed firmly, but interlocked with mortises or notches, and then glued firmly. This is the best quality sofa.
3, high quality fabrics
When purchasing a leather folding sofa bed, the leather surface should be full of luster, no scars, fine lines, and wrinkles can disappear or not be obvious after sitting, so the leather is the first-class leather. When choosing a fabric folding sofa bed, you should carefully observe whether the fabric is delicate, thick and wear-resistant. Choosing a sofa bed with a detachable bedspread is not only convenient for cleaning, but also can be replaced with a new bedspread in the future to increase the sense of room change.
4. Sponge and elasticity
High-grade sofa cushions and cushions should use high-elastic foam sponges, with densities above 30 kg/m3 and 25 kg/m3 respectively. In order to improve the comfort of sitting and lying, some foams are softened without reducing the density, and some cushions are provided with vertical springs, which make the sofa have higher resilience and aging resistance.
