I loved this mattress in store. It was delightfully firm and supportive, while also being really comfortable and seemed like it would offer me the support I really wanted and solve the aches and discomfort I was experiencing with the mattress I had at the time. It was notably more than I intended to spend, but it was on offer and I felt it would be a worthwhile investment. I wish I hadn't bothered. I really wish I'd just gone for a much cheaper mattress from an online store. I think the quality would have been comparable, the cost a lot less, and the delivery much faster. Within a few weeks, despite turning the mattress as required every wee (and boy, is this mattress heavy) it had developed a noticeable dip. When I took photos of this dip and sent it to Bensons, I was told this was normal, did not look like a fault and therefore I could not get a refund. I was offered to exchange my mattress under the 40 night guarantee, but told that I would have to pay 10 percent of my original purchase price to do so, and pay another delivery charge of £49. Also, because my mattress had been on sale when I ordered it, if I simply chose the same mattress again (in the hopes this was just a faulty mattress) I'd have to pay the difference of several hundred pounds. I pressed the issue, and a technician was sent out to see if the product was faulty. He was very nice and empathised with my frustrations, but he said, according to Bensons, this type of dipping, even within weeks (and despite it causing me back pain) was considered acceptable. I understand that some settling is normal, but a dip of over 1cm (nearly 1.5cm) in under 3 weeks? That's not acceptable to me. Especially not at this rice point. It's very noticeable when lying on the 'edge' of the dip, and I can feel myself rolling in to it. I'm just really disappointed. The pre-sale service I received in store was great, but the product is clearly not of an acceptable quality, and the after-purchase customer service was very poor. I have attached the photo of the dip so you can see for yourselves.
