Kurl-On — new ortho mattress 5 inches

Address:	Khordha, Odisha, 751024
Website:	Kurlon

I purchased a queen size ortho lumbar support mattress a week ago and have been sitting and sleeping on 1 side of the bed. Within just a week the side of the bed i was sitting on got depressed and it is clearly visible as a huge depression in the bed. I was told during the purchase that this would not happen. We are highly unsatisfied as it looks very unpleasant and does not support my back any longer. I would like to exchange it for a new one. Please help me out regarding this.
