Once I had opened the mattress plastic bag I realised that the mattress was dirty. I called the mattress on line customer services and they blamed the courier company immediately. Did not take a breath or let me finish my sentence before blaming the courier company. My guess is that the mattress was second hand and being sold as new. Smelt it and it did not have any tiny smell of new. I guess this company is dishonest but the product is good. Be careful and get photo graphs of the mattress before they send it to you. Especially if you gt your own courier company to pick it up.
