THE HEIGHT OF DECEPTION.

Several TV commercials are telling viewers that they should change their mattress every eight years. I think this is a complete lie and shocking example of a lack of truth in advertising. I have had my Sealy mattress for 15 years (nearly twice its supposed lifetime) and it looks and weighs exactly what it did when I bought it. The idea that it would gain weight from skin cells or whatever is absolutely ludicrous.
Do these skins cells burrow through the sheets and mattress cover? Of course not. If your mattress is comfortable, even after twenty years, keep it. Unlike the distant past, mattresses are now a high ticket item. We would have scoffed years ago at the idea of spending $1,000 or more for a mere mattress. And now that they have made the damn things even higher, one must also spend far more on deeper sheets. I would suggest the bedding industry has become a very lucrative racket, not only for the high cost of mattresses, but the fallacy that you're kind of slob if your mattress is older than eight years and your sheets aren't 10,000 count fine Egyptian cotton!
