How often should you be replacing your bedding? Experts weigh in

It's probably time to give everything a refresh.

Between sleeping, relaxing and the occasional WFB (work from bed) days, we spend a lot of time in bed.

Unfortunately, with all that lounging, the area can get pretty gross. Things like dead skin cells, hair, dust mites and sweat can accumulate on your bedding, pillowcases and mattress over time, says Dr. Philip Tierno, a professor of microbiology and pathology at the New York University Grossman School of Medicine. While it's pretty disgusting to think about all those things hanging out with you in your bed, it's more than just the ick factor you should be concerned about: The particles in your bedding can also exacerbate allergies and asthma or even cause you to develop new allergies, Tierno said.

How often should you be washing your bedding?

To prevent this build-up, it's important to wash all your bedding regularly. Tierno recommends washing sheets and pillowcases every two weeks, and comforters every three months or so.

How often should you replace your bedding

Turns out, washing only goes so far. To maintain good bedroom hygiene and stay on top of the wear and tear that comes with frequent cleaning, you should also be upgrading your bedroom essentials pretty regularly. As previously reported by TODAY, you should be replacing your pillows every year, your mattress every five to 10 years and your bedding every 18 to 24 months.

With that in mind, we rounded up some of our favorite sheets, duvet sets, mattresses and pillows to shop when yours need an upgrade — because you really don't want to be thinking about those dust mites as you drift off to dreamland.

You’re sure to love the luxurious feel, but if you’re not totally convinced, the company has a 100-night sleep trial policy. If you don’t love them, you can send them back (also for no cost).

Something to note
  • Pricey compared to others

Sizes: Standard, queen | Colors: 1 | Fabric: Memory and polyurethane foam

Side sleepers unite! While the sleeping position is often advised against, this pillow helps provide support for those of us who still do it. From the first night, writer Emma Stessman felt a difference in the comfort and support this pillow provided compared to others she's used.

Plus, the incorporation of multiple amounts of foam allows it to hold its shape and remain comfortable and breathable, according to Stessman.

Pillow Cube Side Cube Pillow

What we like
  • Long enough to turn from side to side
  • Comfy memory foam but still firm enough to keep your head from sinking in

Traveling often? Associate editor Kamari Stewart totes this as her "ride or die," no matter if she's in a hotel room or her New York City apartment. As a self-proclaimed side sleeper, Stewart appreciates the length of this pillow, allowing her to turn from side to side and remain on it.

"Since it’s a cube shape, it tucks in comfortably between your head and shoulder," she says. "It’s the perfect height to keep everything aligned throughout the night and keeps me from waking up with aches and pains."

  • Adjustable might not always be a perk, can be hard to find the perfect fit

Searching for the perfect pillow can often turn into a Goldilocks situation. Firm pillows feel way too hard, but the softer options don’t provide enough support.

What we like
  • "Uniformly shaped" 
  • "Cooling, soft, high-quality"
Something to note
  • Packaging and delivery issues

A cover can double the life of your pillow, and this one comes with one that’s said to be soft, breathable and machine-washable to make cleaning easier. The foam pillow is made with cooling beads which will pull heat away from your body to help prevent you from getting too hot during the night, the brand says.

What we like
  • Ergonomic shape
  • Effective for any position
Something to note
  • Awkard shape for pillowcases
  • Too flat for some

Sizes: One size | Colors: 5 | Fabric: Memory foam

Rather than stack pillow on top of pillow to provide her with the utmost comfort while sleeping, senior editor Jess Bender opted for this one pillow to solve her sleeping woes.

"Since getting this memory foam pillow, though, I’ve never needed to worry about achy mornings," she says. "I especially adore that it perfectly hugs and positions my head, even when I toss and turn in the middle of the night."

Mattresses

  • Packaging and delivery issues

Sizes: Twin- King | Colors: N/A | Fabrics/Materials: High density foam

Just as the name would suggest, this Allswell mattress provides a high level of support, thanks to a two-inch layer of high-density foam and a firm top layer, the brand says. It also features individually-wrapped inner coils, to help minimize motion transfer, so you can sleep through the night even if your partner is tossing and turning.
