In geomantic omen, the size of sofa and TV cabinet is bigger and smaller.

the size of the TV cabinet should be determined according to the size of the room, as well as personal hobbies and reasonable collocation with other furniture. Generally, the TV cabinet is two-thirds longer than the TV, and its height is between 4 cm and 6 cm. Generally speaking, there is no fixed size requirement. However, we have to grasp one thing, that is, when choosing a TV cabinet, the height of the TV cabinet should make the user's line of sight fall right in the center of the TV screen after sitting. Take watching TV on the sofa as an example-the height of the sitting surface is 4 cm, and the height from the sitting surface to the eyes is usually 66 cm, which is 16 cm together. This is the height of sight, and it is also used to measure whether the height of the TV cabinet meets the standard of healthy height. If there is no special need, it is best not to exceed this height from the TV cabinet to the center of the TV. If you choose a non-dedicated TV cabinet to be used as a TV cabinet, a cabinet 7 cm high is the upper limit. Take a 29-inch TV as an example. The cabinet is 6 cm high and the cabinet is 7 cm high. Together, it is 13 cm. It is estimated that the height from the center of the screen to the ground is about 11 cm, which is just in line with the healthy height of normal viewing. If the selected cabinet is higher than 7 cm, the central line of sight must be higher than this standard, which is easy to form a look up. According to the principle of ergonomics, looking up is easy to make the neck tired and damage the health of cervical spine. This method can be used to calculate the health height of the TV cabinet in the bedroom.

the dimensions of the TV cabinet are determined as follows: (1) low cabinet

if a 29-33 inch TV is used, the following three dimensions should be adopted for the low cabinet

①4mm, which is the sitting height. For example, one side of the hall cabinet can be used as a seat (a thin cushion can also be placed on it) to talk to the sofa. Bedroom low cabinets also use this height.

②6mm, which is the height used to enlarge the TV.

③ 71mm, which is the maximum limit.

why is 71mm the maximum limit?

When sitting on the sofa watching TV, the height of the seat is 4mm, and the height from the seat to the eye is 66mm, which makes it 16 mm. This is the upper limit of sight. If you use a 21-25 inch TV set with a 1mm low cabinet, the sight is just in the center of the TV screen. If the low cabinet is higher than 71mm, it becomes looking up. According to the principle of ergonomics, looking up is easy to cause neck fatigue. As for the distance between the TV screen and human eyes, it is at least 6 times the width of the TV screen. For a 18-21-inch diagonal TV set, it is at least about 244mm, which is the standard size, the short side is 183mm, and the long side is 35MM. If it exceeds 35 mm, the picture of the 18-21-inch TV set is too small, and the sound should be appropriately increased to make the indoor sound exceed the normal level.

(2) sofa size

Generally, a single-seat sofa in a house is 76mm×76mm, and 81mm×81mm at most is enough. The length of a three-seat sofa is generally 175－198mm. Many people like imported sofas. It should be noted that the size of such sofas is generally 9 mm x 9 mm. Putting them in the living room of small units often makes the living room look small. Many people like corner sofa, the corner position should be a few, and the size is also 76 mm x 76 mm. If the corner is made into a sofa, the person sitting will occupy the position next door and feel uncomfortable at the same time, because his feet are at a right angle. To sit comfortably in the corner, the size of the corner sofa is 12mm×12mm. The highest position of the seat should be 4mm, and then the seat should be inclined downward with an inclination of 6, and the depth of the seat should be about 53mm (according to the principle of ergonomics, it can't be too deep, that is, it can't sit in the end, and the foreign sofa of 1mmx 17mm only increases the armrest and back, and the sitting depth increases by 24 inches). The armrest of sofa is generally 56-6 mm high. Therefore, if the sofa has no handrails, the height of the corners and sides should also be 6mm high if the corners are used. It is convenient to pillow hands, make phone calls, write, put desk lamps, etc. Sofa should be moderate in hardness, and sofas that are too hard or too soft will sit with backache. So, how to judge the softness of the sofa? If you sit down and your body is beaten, you feel as if people are sitting on a hard board. This kind of sofa is too hard. If you sit down, your body sinks too deeply, you feel empty, and even feel the bottom frame of the sofa, this kind of sofa is too soft.
