How often do you buy a new mattress?

I bought a memory foam mattress this year, its amazing

I've got bed bugs older than that.

you have a mattress? 😳 you must be city folk

The number is a tad high. It isn't just the stains that age a mattress, but body fibers released each night. That is what the brownish "stains" on it is. It is years of tiny body fibers (dead skin) released each time you lay on it.
This came from a dermatologist I had once who gave me a lot of advice about using a wash cloth and rinsing it out after each use since there are fibers on it after each use, as well. Much of the fibers come from you head and back, so whenever I dry, I use the towel as a washcloth and change towels after every few showers. Now, my towel has brown fibers on it!

I have problems with my back, SO I bought an orthopedic mattress/pillows 3 years ago, was kinda expensive but totally worth it.

I've had the mattress, no the whole bed, ever since I outgrew my crib!

I guess so
I inherited from my grandma

Sure is and none the worse for wear...i don't believe that 8-year crap, they wouldn't have warranties on mattresses for 10-15 years if it was true.

9 years now. But it's a high quality mattress and honestly just as comfy as the day I got it!

8 years is unbelievably long. Once a year should be okay.

I thought it was 7, oh well, I just bought a new set. Very comfy.

Probably lol im only 19. I didnt buy my mattress 😂

this one 5 years so far.. last one 17 years

Depends on how much use it gets. 😆

I've had mine for 15 years.. it's a name brand and is still quite comfortable but it IS getting a little worn... Probably has a couple more years in it..

It used to be only when I had to buy one did I. But, in the last 15 years I've had three beds and I'm about to buy a new one.

No.... not yet... but they do make them to last longer...

I'm averaging about every 10-15 years right now...

Nope, ours has four more years to go.

3 years
