New double bed, never used, bought from Ashley, turned out too big for the room

The bed is clean and new, never used, I haven't even bought a mattress yet. I thought it was a 170 cm wide bed, but it turned out to be 200 cm wide and 200 cm long, meaning two meters by two meters, a very large king size, and it turned out too big for the room. I bought it three months ago, and when I opened it, I found it too big for the room. I bought it from Ashley, its color is cream
