The base I got with the gray chair is brass/gold. It is nowhere near rose gold. It is totally fine for me as I read another review and was hoping to have the brass. Not too difficult to assemble-- have to kind of twist and push to pop the wheels in. I could not believe the whole chair fit in the small box that arrived. The plastic does flex and creak when you lean back. Perfect scale for a low profile chair for a smaller bedroom desk. I would describe as small/medium for sizing. Beware of fingerprints, it shows them well.
