I'm interested in learning more about the leather sofa you offer. Could you provide details on its construction, materials used, and any specific design features that make it stand out? Additionally, information on available colors, sizes, and any customization options would be helpful. I'd also like to know about the sofa's comfort level and durability. What kind of warranty do you offer, and how should it be maintained to ensure longevity? If you have any recommendations for complementary pieces or collections that pair well with this sofa, please share that info as well. Thanks!
