Purchased the mattress August 2018. We've had it less than 3 years and myself and my partner are really suffering physically and my partner mentally. He is currently going through issues with his mental health and part of his recovery is to be having decent sleep patterns. This isn't happening, we're sleeping on our sofas, which disconnects us emotionally too. I have recently had an mri on my back for the pain, not helped by the mattress. There is a dip in the middle of the mattress, almost like it's fallen in, making my partner and i roll into eachother alot We work long hours and it's affecting us. I have contacted bensons, sent pictures per their request, only to receive a phone call to say as we have a slight stain on our mattress (nothing to do with the dip) it voids our guarantee. So we're left with a mattress which causes us such pain and discomfort. It's a mattress which we sleep on, with a mattress protector, but of course it will encur some day to day discolouring. I find it extremely distressing to think we're stuck with this mattress because of something their pointing out has nothing to do with the fault! We have cared for the mattress the way we were told. I asked to speak to a manager, which of course couldn't happen. I was told to use a spirit level to display the dip, which I have sent off pictures today. I was also told I can call home serve who will charge me £48 to come and see the mattress. My partner has been out of work due to coronavirus so this isn't really an acceptable sum of money to depart with, thinking it'll be a waste of time, also to be told we "might be" reimbursed 'if' they find a fault, something I have read so many reviews on surrounding similar situations and it seems bensons take no care for their customers or take their problems or faults in a serious manner. I feel like I've been pushed to the side and to get on with it really, not the customer service I expected having paid over £1000 for the mattress. We're still between the sofas and bed, not sure what the resolution is.
