The service life of a sofa is affected by many factors, including material, brand, frequency of use, maintenance status, etc. The following are some possible influencing factors and their corresponding service life:

Leather sofa: A high-quality leather sofa usually has a long service life, which can reach 7 to 10 years, or even longer if it is well cared for and maintained12. However, if the quality of the leather sofa is poor, its service life may be greatly reduced, and problems may occur within two or three years.

Solid wood sofa: Solid wood sofa has a long service life and can theoretically be used for forty or fifty years, provided that the material is strong and not easily deformed.

Fabric sofa: A fabric sofa with good quality can be used for more than ten or more than twenty years if it has good spring and bandage support and a high mesh density3.

Other factors: The service life of the sofa may also be affected by the use environment and habits, such as direct sunlight, daily cleaning, etc. In addition, the appearance and usage status of the sofa will also change with time and use, requiring regular maintenance and cleaning1.

Warranty period: Some sofa suppliers will provide a certain warranty period, usually around 3 years, but the longest will not exceed 5 years4.

To sum up, the lifespan of a sofa varies depending on the type and quality, ranging from a few years to decades. To ensure the long-term use of your sofa, it is recommended to take appropriate maintenance measures and conduct regular inspections and repairs.
