Description

Technical Field

[0001] The utility model relates to the field of sofa design, and in particular to a translatable sofa frame. Background Art

[0002] A sofa is a commonly used piece of furniture, mainly used for family members to sit on. In the past, most sofas were completely fixed, so after the sofa was manufactured, its various structures would not change and could not be adjusted.

[0003] Since the above-mentioned sofas are usually completely shaped, that is, the sitting length of the sofa is not adjustable. In actual sofas, the sitting length of the sofa is usually short. However, sometimes users hope that the sofa can be extended to facilitate the placement and support of their feet or to facilitate lying down. If the sitting length of the sofa is directly set too long, it will result in a large floor space for the sofa, which is likely to hinder the daily life of users and is rather inconvenient.
