First of all, check if the sofa bed is soft and moderate, and the balance is elastic. If you can, feel it on your face. Whether you are lying on your back or lying on your side, you can maintain the normal posture of your bones and muscles. This sofa bed is the most comfortable.
Note that there are no sounds in the four corners. If a poor quality spring is used, the bed angle of the sofa bed is the easiest to find quality problems, because good springs will not experience sound when exposed to pressure. Pay attention to the height of the bed, it is inconvenient to go to bed too high, and the low level affects human health, because dust gathers most at a distance of about 30 cm from the ground.
Clean and maintain. On a regular basis, you should use a brush to remove dust, or concentrate the dust and then use a vacuum cleaner. Do not force it to avoid unnecessary weight load, so as to extend the life of the sofa bed.
