What is a "last years model" ? Quite obviously it's a model that is no longer the newest. In mattresses however it really could be found gold, as in additional savings! For most people the color or fabric or model year doesn't matter. All that matters is that we need a new one, so here is what to check and the questions to ask. Is it brand new, fully warranted and comfortable? Can the dealer prove that it sold for more than you are buying for? Why is it discontinued? Usually its just like the typical model year change. With mattresses the technology is still good from year to year. Unlike a car the value is not less because it's a year older, it's just that the store needs to clear out old stock.
