The single sofa is suitable for a single room or a study. Divided into double support single sofa, single support single sofa, no support single sofa. Single sofa , as the name suggests, a sofa where a single person sits. Styles are colorful.
Point 1: Comfortable
When you buy any sofa, you must try it. When you sit, you must grasp the softness and fit. If you are too soft, you must be vigilant. A sofa that is too soft may not be a problem with quality, but the "sense of collapse" makes it easy to become a "sofa potato."
The easiest way to judge whether the sofa is good or not is to sit for a while. If you only move three times in an hour, this is a good sofa; a good sofa can hardly feel the existence of the sofa, but you can feel the strong support; A good sofa generally has a zipper on the bottom surface, which allows you to pull open to check the spring and fillers; a good sofa is comfortable to sit in various postures, and it will sink deep in it when sitting cross-legged; it will be moderately soft and hard when you sit normally; a good sofa will be heavy , But leather sofas are generally heavier than cloth sofas; the springs of good sofas are subject to noise reduction.
Point two: strong sense of design
Good design is also reflected in whether the design of the sofa structure incorporates a considerable amount of technology. For example, the very home sofa uses a type of blue steel spring, which is not only good in elasticity but also very strong.
Point three: pay attention to details
The details of the sofa , in addition to what you can see, such as whether there are defects, whether the pins are fine, whether the width of the cushion plus the ratio meets your physical needs, and whether it is in harmony with the sofa as a whole. In addition, there are some details that are relatively easy to overlook, so be sure to pay attention when buying.
Sofa feet. Some sofa legs are made of wood, some are made of metal, and some are made of pulleys. This detail should be checked carefully. The main thing is to see if it is strong. If this part is unstable, the sofa will not be comfortable to sit on.
frame. Many sofas use a frame and cushion structure, such as exposing shiny metal and leather materials to create a wild and uninhibited effect. Then this part of the exposed frame should be checked clearly, and there should be no small flaws that affect the overall effect.
Sofa cover for fabric sofa. Be sure to check carefully whether it is easy to disassemble to facilitate cleaning in the future. Some sofas claim to use high technology, and the fabric is impervious to water and oil. You must do the experiment yourself to avoid being fooled by the "uncommon" so-called high technology.
Filler for the sofa . A good sofa filler must be environmentally friendly. When you buy, you must open the zipper of the sofa and check carefully. If there is no zipper, you must ask the shopping guide to issue a corresponding monitoring report. .
