New Sofa for Urgent Sale

I have a new sofa in its original packaging, and I want to sell it urgently. By God, it's still in its original packaging. The reason for selling is that it doesn't fit my living room—my living room is small, and this sofa requires a smaller space. It's an L-shaped sofa, and even its invoice is still with me. It's fully covered by warranty. The entire sofa is made of foam—no wood at all—and is extremely comfortable. I bought it for SAR 2,100 and am selling it for SAR 1,900 because it's entirely foam, and the foam warranty guarantees repair if it deteriorates.
