How Often Should You Replace Your Bedding? A Complete Guide to Bedding Lifespans

How Often Should You Replace Your Bedding? A Complete Guide to Bedding Lifespans

If you can’t remember the last time you swapped out your sheets or bought a new comforter… it might be time. While bedding may seem like a long-term investment, it doesn’t last forever—and worn-out bedding could be affecting your sleep more than you think.

Let’s break down how often you should replace each part of your bedding—and why it matters.


Sheets: Every 1–2 Years

Sheets go through a lot—sweat, body oils, frequent washing. Over time, this wear breaks down the fibers, making them rougher, thinner, and less breathable.

Replace when:

  • Fabric feels scratchy or thin

  • Color is faded or yellowed

  • Elastic on fitted sheet is stretched out

Pro tip: Rotating between 2–3 sets can extend their life.

Pillows: Every 1–2 Years

Even with pillow protectors, pillows collect dust mites, allergens, and bacteria. They also lose their shape, which can impact neck support.

Replace when:

  • It no longer bounces back when folded

  • It smells musty or feels lumpy

  • You’re waking up with neck pain

Comforters & Duvets: Every 3–5 Years

Comforters and duvets last longer but still need replacing—especially if they lose their fluff or show signs of wear.

Replace when:

  • It feels flat or doesn’t keep you warm

  • The filling is clumped or uneven

  • There are stains or persistent odors

Mattress Protectors: Every 1–2 Years

These are your mattress’s first line of defense. Frequent washing wears them out faster than you might expect.

Replace when:

  • It’s torn or no longer waterproof

  • It’s lost elasticity

  • You’re upgrading your mattress
