Do luxury mattresses wear out just like inexpensive mattresses?

Yes, they do, but they wear out later. So your inexpensive mattress may wear out in 3 to 5 years. A luxury mattress, 10 to 12 years. You get what you pay for.

Don't worry about the price of the mattress. Say you buy a $10,000 top-of-the-line mattress and adjustable base. It's going to last you and your partner for 10 years.

That's $1,000 a year. That's, what, 3 bucks a night, $1.50 apiece. That's less than you're paying for one cup of coffee.

So if $1.50 a night is for 8t hours of your life that recharges, rejuvenates, gets you ready to go in the morning, I think that's an investment well worth it.
