Maybe you've had the same question too: How long?
How long is the life of a pillow?
According to an article written by Kelli B. Grant at Yahoo Finance (Feb 2007):
Replace after: Two years
Why: Pressure on the pillow as you sleep causes it to flatten, and develop uncomfortable bumps and lumps, says GHI's Huddy. To test if your pillow still has life in it, she says, fold it in half and rest your hand on top for 30 seconds. Then let go. "If the pillow pops back, it's fine," she says. If it remains folded, it's time to buy a new one.
Life the Green Way, a blog out of Birmingham, shares similar information:
It is also important to note that although people get fitted for shoes and clothing, they rarely get fitted for a pillow, and they should. Purchasing a good-quality pillow that feels like a good fit will enhance good sleep and will also give you a starting point when replacing your pillows within that 2-to 3-year timeframe."
"Sleep experts recommend replacing top-quality pillows every 2 to 3 years and never using a cheap pillow for more than a few months at a time.
You'll also find some great information there about allergen concerns in regard to your pillows.
So, now we know. If you still have pillows handed down from your parents or from the early years of marriage it's time to update. And fall is a great time for refreshing your home before you think about closing the house up for cooler weather. If you have questionable pillows, why risk poor sleep and possible allergy problems?
And if you're looking for a deal, I've always found that TJ Maxx or Ross stores have a great selection of quality pillows at great prices.
