I was pleasantly surprised by the quality of this mattress for the price paid.When I opened it there was quite a strong odour but after leaving it to expand for a day the smell had gone.I have slept on it and it is quite firm.I had a very soft mattress which was wrecking my back.I can sleep soundly and I wake with less pain.It will take a few nights to get used to it being firmer than my other one but I am well pleased with it.The delivery was a week earlier than estimated and postage free.The cost of the mattress is half the price of any I could buy in N.Ireland and delivery charges by some on top of that.I would highly recommend Way fair for ***** service.I have no hesitation buying from them again.
