After sleeping on the mattress, which is definitely more comfortable than our old one, we will be requesting an exchange for the extra firm because the firm that we ordered is just not firm enough.
I must say though, that I am disappointed in the after sales customer care. At delivery we realised that the wrong pillows were put n the order form, which I did not pick up at the time of the order. When I called the shop, I was told that they can't do exchanges in the shop and that I would have to pay £10 extra per pillow becuase the special was over. I know which pillows I ordered at the time of the order and I believe that the wrong pillows were deliberately put on the order and if caught at the time would have been corrected, but because I only caught it after delivery, I was told I would have to pay more. I think the customer service like this after such is big order is disappointing. 2 stars for that.
