In the last ten years, the price of a mattress has indeed gone up. And if consumers were to assess the cause, it would have to be in the materials and technology adapted to make the perfect one. As most mattresses were likely to sag when compressed, the latest innovation such as memory foam has made it possible for a mattress to maintain its shape and quality years down the line. The average price of mattresses today cost anywhere between $500 and $1,600.
But in as much as the price has gone up, most mattresses today are also twice as thick and durable than the last decade. So, essentially, you really should be getting what you pay for.
