If you can’t remember, it’s been too long. Most UK households replace their sofa every ten years, their mattress every eight — and their duvet and pillows roughly never. They get washed occasionally, aired out when guests are coming, and quietly kept for a decade past the point of doing their job.
Bedding isn’t furniture. It has a working life, and when that life ends, you notice it in your sleep before you notice it in the fabric. Here’s the honest timeline.
Pillows: 2–3 Years
The shortest lifespan in the bedroom, and the one most ignored.
A pillow’s job is to hold your head and neck at a consistent height all night. Over two to three years of nightly compression, the filling breaks down and stops springing back — which is why an old pillow needs folding, punching and propping to feel right. If you’re doing any of that, the pillow has already retired. You just haven’t told it.
There’s also the less pleasant maths: a pillow absorbs sweat, skin cells and dust mites every night for years. Washing helps, but it can’t reverse a flattened filling.
The test is simple. Fold the pillow in half and let go. If it springs back, it’s fine. If it stays folded, it’s done. You can find sensible replacements at Absolute Home Textiles without the inflated pricing that tends to follow the word “sleep” around — and replacing two pillows costs less than one dinner out, for something you use eight hours a night.
Duvets: 5 Years for Synthetic, Longer for Natural Fill
A duvet’s warmth comes from trapped air, not the fabric itself. As synthetic filling compresses and clumps over roughly five years of use, it traps less air — which is why an old duvet feels heavier yet keeps you less warm. People usually blame the radiator, the window or the weather. It’s the duvet.
The visible signs: filling that’s migrated into lumps, cold spots you can feel through the cover, and a duvet that’s gone flat and limp rather than lofty.
When replacing, the tog system does the actual work — 4.5 tog for summer, 10.5 for spring and autumn, 13.5 and up for winter.An all-seasons duvet (a 4.5 and a 9 that button together) is the practical answer if you don’t want two duvets in storage. This range of duvets by tog covers the full spread, including anti-allergy options — worth choosing if anyone in the house wakes up congested, since the filling is treated to resist the dust mites that build up in older duvets.
Bed Linen: 3–5 Years, Depending on What You Bought
Sheets and duvet covers wear out more gracefully than fillings — they don’t fail, they fade. Cotton thins gradually with washing, colours dull, and elastic in fitted sheets gives up long before the fabric does.
The lifespan difference is mostly down to what the linen was made from in the first place. Decent 100% cotton or a quality polycotton survives years of 60°C washes; bargain-bin sets go bobbly and translucent within eighteen months. This is one of those categories where the mid-priced option is genuinely the cheapest over time, because you replace it half as often.
If you’re replacing bedding across more than one bedroom — or you let out property and need the same linen in every room — buying in bulk makes obvious sense. British Wholesales supplies household-quality bed linen at bulk prices with no minimum order, making it a popular choice for landlords and holiday-let owners who prefer to buy once for five rooms rather than five times for one.
The Things That Outlast Everything
For balance: mattress protectors and pillow protectors barely degrade — replace them when they’re damaged, not on a schedule. And a good blanket or throw lasts decades. The replacement cycle applies to the things that compress and absorb, not the things that simply cover.
The Five-Minute Audit
Tonight, before bed: fold each pillow in half and see if it springs back. Hold your duvet up to the light and look for thin patches and clumping. Check your fitted sheet’s corners for dead elastic.
Most people find at least one item that should have gone two years ago. None of it is expensive to put right — and unlike most home improvements, this one improves the third of your life you spend asleep.
