We bought a Benson king size bed and mattress 2 years ago. Recommended by the sales guy as good as any brand out there. How wrong we were to believe him. We have just ordered a new Silentnight mattress elsewhere because unfortunately the Benson one has not survived even 2 years. I regularly turned the mattress aligned to the instructions at least once a month, it could not be turned over, just turned around 180 degrees. There is a very big dip as if the coils have come apart( a big V dip) on my side, I am about 16st . When I contacted Bensons, they suggested that the 5 year warranty would not cover this, but if I paid £50, for a third party to come out to see if it was covered under warranty, it may be covered. In my mind this is a company that does not have faith in its own products, why do we have to pay what I believe is an insurance indemnity so if it was deemed as warranty, would cover the cost of a replacement mattress meaning that Bensons get away with selling sub standard products. I will never buy anything else from Benson for Beds for that reason alone. Can't wait unbroken the new mattress arrives and I can throw the Benson one away. Do not get caught out.
