The standard size of a two-person dining room stand is 121* depth 61* height 111cm, and the other is a four-person dining room stand. The size of this four-person dining room stand is about 121* depth 121* height 111cm, which is the standard size of a dining room stand. 1. The width refers to the maximum distance between the two handrails from the left to the right of the sofa, which is the "length" of the sofa in the usual sense. 2. Seat width = width-handrail width *2? The single person, two people and three people of the sofa are determined according to the width and seat width, because these two data determine the seating length of the sofa. Depth refers to the maximum distance from the front to the back of the sofa, including the backrest, which is commonly referred to as "width"? 3. Seat depth = depth-thickness of reclining. Due to the requirements of style, it is normal to have a sofa depth of 81-111 and a seat depth of 55-71, but some friends like a deeper sofa because they will feel relaxed when sitting on it. But the depth should not be too big: the first is to consider the style. The second is that the depth is too great, so it is difficult for people to lean on the back of the sofa. The third is that the edge of the sofa just falls in the middle of the calf, which will affect the comfort. The height refers to the maximum distance from the ground to the top of the sofa, which is the same concept as the usual "height". Seat height = the distance from the ground to the seat surface. The seat height of European and American big sofas will be between 43 and 47. Because of the Asian figure, it is basically OK to have a height between 41 and 45.
