content: I was happy first as i received the mattress, very fast shipment, great communication with the seller. But unfortunately this mattress wasn't the best choice for my back as it gets softer after couple of days of sleeping on it, even that I weight 159lb, its still going deeper and deeper. To return it, not so easy, once you unpacked it from vacuum sealed bag, you will never get the same thin shape of it, to send it back will cost you the price of the mattress.
