Mattress is very good. However, I purchased a Mattress Protector Perfect Partner' designed to compliment this mattress and upon opening it it said it was not to be used with an electric blanket. As I use an electric blanket all winter, it means this product (which cost 54.99) is useless for me. I would point out that this warning is on a label on the protector and nowhere on the packaging did it show this warning. I took it back to the shop but was told they could not refund or exchange for a diffent protector, because I had opened it. I explained that I had opened it in good faith, never expecting to see that warning. The Salesman rang a Manager in another store and the confirmed that because I had opened it, it could not be returned. The Salesman also rang Bensons Customer services, who said the same. I rang Customer Service myself and got absolutely nowhere. I was told by the person I spoke to that I could not speak to anyone in a higher position than him, as apparently that person does not exist! So, I have a 54.99 Mattress Protector, which is just about to go in the bin. I am shocked by Bensons after sale service. Whilst purchasing the bed and the mattress everyone was very pleasant and efficient. I suppose that is because I was spending 2000+ I have 60 days to return the bed if I don't like it. I am tempted to because of the incident with the mattress protector.
