Care & Maintenance
A mattress is one of the biggest single purchases in the home, and simple habits make the difference between a bed that sags in three years and one that stays supportive for close to a decade. Here's what actually protects your investment - starting with the single most effective step, a mattress protector.
Start with a mattress protector
If you only make one change after reading this guide, make it this one. A mattress protector sits between you and the mattress and takes the hit from spills, sweat, dust mites and everyday allergens before any of it reaches the actual bed. Without one, moisture and body oils work their way into the comfort layers over months and years, breaking down foams and fabrics from the inside - damage that no amount of cleaning can undo afterwards.
Choose a protector that's waterproof but still breathable, so it doesn't trap heat overnight, and make sure it fits your mattress snugly with no bunching. Wash it regularly along with your sheets. It's a small, inexpensive layer that does more for the working life of a mattress than almost anything else on this list.
Rotate and flip on a schedule
Sleeping in the same spot every night puts repeated pressure on the same section of a mattress, and over time that shows up as a body impression or soft patch. Turning the mattress end-to-end every few months spreads that wear more evenly across the surface, so no single area is doing all the work.
Whether you should also flip it top-to-bottom depends on the build - many modern pocket spring and foam mattresses are one-sided by design and are only meant to be rotated, not flipped. Check the care label or manufacturer's guidelines for your specific mattress before flipping, since flipping a one-sided mattress can put the comfort layers in the wrong position.
Keep it clean
A monthly vacuum over the surface lifts out dust, skin cells and allergens before they build up in the fabric. If your mattress has a removable, washable cover, follow the care label and wash it on the recommended cycle. For a spill or stain, blot it with a mild detergent rather than scrubbing, and avoid saturating the mattress with liquid - excess moisture that doesn't dry out properly is exactly what encourages mould and mildew inside the layers. For a full step-by-step method, see our mattress cleaning guide.
Check the base and foundation
The mattress is only half the sleep system - the bed base or foundation underneath does a lot of the structural work. A base that's sagging, has broken slats, or simply isn't rated for the mattress on top of it will cause uneven wear no matter how well you care for the mattress itself. Inspect your base periodically for wear and address any issues promptly, and make sure it's a genuine match for the mattress type sitting on it.
Keep your bedding just as clean
Sheets, pillowcases and underlays sit directly against the protector or mattress surface and carry sweat, body oils and dust through to it every night. Washing bedding regularly on the manufacturer's recommended cycle keeps that layer from building up and passing through to the mattress underneath - it's a simple habit that supports everything the protector is already doing.
Everyday habits to avoid
A couple of common habits shorten a mattress's working life faster than anything else. Jumping or standing on a mattress - tempting as it is for kids - puts sudden, concentrated strain on the internal springs and comfort layers that they're not built to handle, and it adds up over time. It's worth treating the mattress as a sleep surface only.
Moisture and direct sunlight are the other two to watch. A damp room or a mattress pushed up against a window that gets strong sun for hours a day will see materials break down faster - sunlight can fade and weaken fabrics and foams, while trapped moisture is a direct path to mould. Where possible, keep the mattress in a well-ventilated room out of direct sun.
How long should a mattress actually last
Most quality mattresses are built to perform well for around 7 to 10 years, though that range depends heavily on the build and how well it's looked after. A mattress that's protected, rotated and kept clean from day one will comfortably sit at the longer end of that range; one that isn't will start sagging and losing support well before then. If you're noticing visible sagging, waking up with new aches, or the mattress is simply older than a decade, it's a reasonable time to start looking at our current mattress range.
FAQs
Do I really need a mattress protector?
Yes - it's the single most effective step for extending a mattress's life. A waterproof, breathable protector stops spills, sweat and allergens from reaching the comfort layers, where the damage they cause can't be cleaned out later.
How often should I rotate my mattress?
Every few months is a good general rule, though you should check the manufacturer's guidelines for your specific mattress. Regular rotation spreads out wear so you don't end up with a permanent body impression in one spot.
Should I flip my mattress as well as rotate it?
Only if it's designed to be flipped. Many modern pocket spring and foam mattresses are one-sided and should only be rotated, not flipped - flipping a one-sided mattress can put the comfort layers in the wrong position. Check the care label first.
How long should a good mattress last?
Most quality mattresses perform well for around 7 to 10 years. Proper care - a protector, regular rotation, cleaning and a supportive base - pushes you toward the longer end of that range.
Can moisture and sunlight actually damage a mattress?
Yes. Trapped moisture can lead to mould and mildew inside the layers, and prolonged direct sunlight can fade and weaken fabrics and foams. Keep the mattress in a well-ventilated room away from direct sun where possible.
