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
