Purchased a double mattress for son who at the time was 13 and only 5ft tall, paid £588. Now 3 1/2 years down the line the mattress is useless, DFS refusing to do anything about it. Found out only a 2 yr guarantee, now not surprised as they would not give a longer one as people like me would be asking for an exchange. Got a Marks and Spencer one had for 8 years and still like new, for the same price. Definitely do not buy and mattress from them, go to Marks and guarantee by far better and a lot longer lasting. Worst mattress we have ever purchased and DFS won't do anything about it.
