How Often Should You Replace Your Pillows? 5 Signs It's Time

By Snoozyn · Updated October 2026

How often should you replace your pillows? Pillows wear out so gradually that it is easy to keep one too long, so rather than going by the calendar, go by what the pillow looks and feels like. Below is a quick test and five clear signs.

How often to replace pillows: how long they usually last

A commonly quoted guide is one to two years for a synthetic fibre pillow and a little longer for feather and down. Treat that as a rough starting point, not a rule. How long yours lasts depends on how full it was to start with, how much it is used and how it is looked after. A guest-bed pillow used a few nights a year will last far longer than the one you sleep on every night.

The fold test

1. Take the pillowcase off and lay the pillow on the bed.
2. Fold it in half across the middle and press it down.
3. Let go.

A pillow with plenty of life in it springs open straight away. One that opens slowly is getting tired. If it stays folded, or only half opens, the fill has lost its loft and no amount of fluffing will bring it back. For a king pillow, fold it into thirds rather than in half, because the extra length makes it open more easily.

5 signs it is time to replace your pillow

1. It stays folded, or lies flat

The clearest sign, and the one the fold test finds. If the pillow has noticeably less height than when it was new, and fluffing does not bring it back up, the fill is spent. Our guide to fill weight and loft explains why this happens.

2. Lumps and thin patches that will not shift

Fibre fill can gather into clumps with thin, empty areas between them. Shaking and pummelling breaks up fresh clumps, and a low tumble dry with dryer balls can help, as our guide to fluffing a pillow shows. If the lumps come straight back, the fibre has matted for good.

3. You fold, stack or bunch it every night

If you find yourself folding the pillow double, adding another on top, or bunching it up to get the height you want, it is no longer the pillow you bought.

4. Marks or yellowing that will not wash out

Pillows tend to discolour over time, especially in the middle. If a wash on the setting the label allows does not shift the marks, it is time for a new one.

5. The shell is worn or split

Look at the outer cover. Thin patches, pilling, loose seams or fill working its way out at the corners all mean the pillow is near the end. A small split can be sewn up, but a shell wearing through in several places is unlikely to survive another wash.

How to make a pillow last longer

• Fluff it every morning. A shake from each end and a few pats spread the fill out before it settles in one place.
• Turn it over and round. Swapping which side and which end you use spreads the wear across the whole pillow.
• Keep it in a pillowcase and change the case weekly. Most people wash pillowcases with their sheets once a week. Our guide to how often to change bed sheets sets out a routine.
• Wash the pillow now and then, and dry it fully. Follow the label and our guide to washing a pillow. Every wash adds some wear, so a few times a year is plenty for most.
• Do not use your sleeping pillow as a backrest. Sitting up against it puts a lot of weight on one spot. Keep a cushion or an older pillow for reading in bed.

What to do with an old pillow

Most charity shops do not take used pillows, and many textile banks do not either, so check what your local council accepts. An old pillow can also find a new job as a pet bed or stuffing for a floor cushion, and a slightly tired one is fine as the reading pillow at the back of a stack.

Replacing yours

If it is time, our two pillows come in standard and king, both with synthetic fibre fill and no feathers.

• The classic microfibre pillow insert has a medium-firm feel and costs £23.90 for a standard or £41.90 for a pair.
• The microgel pillow insert has a plush, down-like cluster fill in soft, medium or firm, from £33.90 for a soft standard or £59.90 for a pair.

Not sure which feel to choose this time? Our guide to soft, medium or firm pillows will help.

Frequently asked questions

How often should you replace pillows?

Many people find a synthetic pillow needs replacing every one to two years, but it depends on how full it was, how much it is used and how it is looked after. Go by the fold test and how it feels rather than the date.

What is the pillow fold test?

Take the case off, fold the pillow in half, press it down and let go. If it springs open, it is fine. If it opens slowly or stays folded, it has lost its loft and is due for replacing.

What can I do with old pillows?

Most charity shops do not accept used pillows, so check what your local council recycling or textile banks take. An old pillow can also be reused as a pet bed or as stuffing for a floor cushion.

Can you bring a flat pillow back to life?

If it is just compressed, yes: shake it hard from each end, pummel it, or tumble it on low with dryer balls if the label allows. If it still stays folded after that, the fill is worn out.

Do pillows last longer if you wash them?

An occasional wash, followed by thorough drying, keeps a pillow fresh and the fill moving. Every wash also adds some wear, so a few times a year suits most people.

Should I replace both pillows at the same time?

It usually makes sense, especially on a shared bed, so both sides match in height and feel. If one pillow gets far more use than the other, you may only need to replace that one.
