You already bought it and whether right or not if you stuck with it. You should have done some basic research before buying anything. We have many local brands that very hard to keep track of all of them. To be honest this sofa brand and fabric are unknown to me personally (but that may not say much as there are many out there).

Before you buy the brand is less important. You should have asked what is the sofa frame made from (metal, what type of solid wood used, etc), springs, cushion used, joint, mechanism (if any) and legs. The common good fabric are acacia, aqua clean. Fabric is probably 60-70% of the cost of the sofas.

Anyway 3800 for a sofa is not that bad a price. Mine is more than 10k made with nyatoh frame but much bigger with Aqua Clean fabric. So just accept it and just be more aware when you buy next time
