I'm curious as to what Bensons for Beds considers a guarantee? I emailed to discuss an issue with our mattress sagging where slept on only, despite regular rotation, only to be told that I need to put myself out of pocket in order to prove its a problem with the mattress and not something we have done. Other than sleeping I'm not sure how else we could be held accountable. They are prepared to refund up to £100 of the review but being based in the North of Scotland this could potentially cost me so much more just to get a report that there is a possibility Benson for Beds won't take accountability for. Why offer a guarantee if you have no intention of seeing it through? Strongly recommend that you buy a bed elsewhere with a guarantee that will be honoured.
