Nice topology as shown in preview images. Chair was made mostly by loop tool, not by modifying default object, no modifier in Blender or other plugins. All images textures were made by myself. Make sure model looks realistic and light enough for living room or office scene. Render engine: Eevee.

Updated files contain more realistic material as shown in preview images.

Only quad in model, no N-gons, no triangulates, no vertices with more than 5 edges, other standards also meet CGtrader requirement. No mark seam during UV editing, no overlapping UV. However, I got problem with UV stretch. Please see preview image, I also attached screenshoot for verification from Kodama. Total vertices: 339. Dimension: 45 x 45.8 x 92.5 cm ( Detail in preview images)

I also uploaded Blender file with procedural nodes to make basic wood material with glossy surface , ready to bake image textures( Diffuse map, Glossy map, Normal map) . Please see preview images for your overview. In Blender file, I already set up simple lights to render room scene. However it may be better for night time scene.

Avaiable formats: glb, obj, stl, fbx( both embed and no embed textures). UV maps, Image textures are in zip files

Any question about working process, any idea to improve model quality, please let me know
