I did try this but she is adamant that there is no point "because all mattresses give up after a few years" and "our last one was expensive and didn't last". It was £400 for a king size.
If you look after a high quality (double-sided) mattress by rotating and turning it regularly, it will last 15+ years if it is well made and even longer if you use a topper with it. I'd also ask what relevance lying on a bed for 5 minutes in a shop actually does? It's pretty much the same as kicking the tyres on a car, naff all is the answer.
If you can't convince her by the fact that they offer a 60 days no quibble money back with free collection and up to 10 years warranty on the mattresses themselves, then is sounds to me like she just doesn't want to part with the cash, and would rather buy 2-3 average beds for more money over the same life span and in the process help create more waste and help ruin the environment to boot, with all that craptastic polyester filling you'll be committing too. Sorry for the rant
Co-incidentally I've just had a brand new super-king base delivered this morning to go with our newest mattress, it should add significantly to the comfort level being a sprung divan.
Finally have you watched any of their videos where they take say a £1000 high-street mattress and cut them in half to show you how badly they are made? They then do a comparison to their equivalent at 50-60% less and show how superior it is, in terms of build, and fillings. Ask your Mrs how can places like dreams cut 50% off the cost of a mattress in a sale, it is because most of them are heavily overpriced in the first place, and they are still making a huge margin with that sale price too.
