Sleeper Sofa's buying tips

Point 1: The size of the sofa bed is suitable
When choosing a sofa bed, do not blindly consider the appearance and color of the sofa bed, comfort is also very important, and this is reflected in the size. The size of each part of the sofa should adapt to the curve of the physiological structure of the human body, in line with the principle of ergonomics, so that whether it is sitting or lying down, it will be more comfortable.
The height of the sofa bed seat is preferably between 35-42 cm, which is about the height of the person's calf. Too high or too low is not conducive to the relaxation of human muscles. The seat depth is between 48-55 cm, and the knees should still be outside the seat when the back is as close as possible to the back of the sofa. From the ground, the height of the sofa bed backrest should be between 68-72 cm, and this range is the most comfortable. In addition, the inclination of the backrest is preferably between 100-108 degrees, and the height of the armrest is 62-65 cm.

Point 2: The structure of the sofa bed should be firm
Whether the frame structure of the sofa bed is strong is the most important standard for measuring the quality of the sofa bed, and it is also the basic guarantee for the durability of the sofa bed. If the sofa bed uses a wooden frame, it is best to uncover the base lining to see if the wood is smooth, and a good wooden frame should be free of moths, scars, and decay.
There are two main "variants" of sofa beds: "flipped" and "push-pull". Regardless of the method, during the "variant" process, it should feel smooth in the hand, the resistance should be moderate, and the parts should be stable and firm after they are in place.

Point 3: The spring pad of the sofa bed should not be too soft
Since the sofa bed combines the dual functions of the sofa and the bed, the quality and comfort of the sofa bed spring cushion is crucial. And when choosing, not the softer the spring mattress, the better, the touch of soft and hard mattress can evenly disperse the weight of the human body, strengthen the ability to support the spine, and relieve physical fatigue.

Point 4: Fabric sewing should be meticulous
Most sofa beds on the market are fabric fabrics, so when purchasing, it is best to choose a sofa bed with thicker fabrics, so that it is more durable. The warp and weft threads of the fabric should be fine, tight and smooth, without jumping wires and joints exposed. In addition, it is preferable to have evenly and straight stitches at the sewing points adjacent to the fabric. The color fastness of high-quality fabrics will be very high, and the antistatic and flame retardant properties are good.

Point 5: The wrapping should fit naturally
Wrapping, which is the fit between the fabric and the contents. A good wrapping should be flat, and the transition between the armrests and the seat and backrest should be natural, smooth, and free of wrinkles. Especially if the sofa bed has some curved positions in the design, you should check carefully to see if the wrapping cloth is smooth and smooth. In addition, the splicing of the wrapping cloth on the décor should also be checked - whether the splicing of the pattern in two different positions is coordinated, and if it is a stripe pattern, pay attention to whether the stripes are twisted and tilted.
