How to Care for & Clean a Mattress

A good mattress is one of the hardest-working pieces of furniture you own, supporting you for roughly 3,000 hours a year and absorbing perspiration, skin cells and dust along the way. Yet most people never rotate, protect or clean theirs until something goes wrong. This guide walks you through the simple, regular habits that keep a mattress comfortable, hygienic and supportive for its full lifespan, plus exactly how to tackle stains, odours and sagging when they appear. Get the routine right and you can comfortably add years of good sleep, and protect the investment you made in the first place.

1. Why mattress care matters

A quality mattress is designed to last roughly seven to ten years, but how close you get to that figure depends almost entirely on how you treat it. Foams compress, fillings settle and springs fatigue with use, and uneven wear is the single biggest reason a mattress feels “done” long before it should. Sleeping in the same spot night after night creates a body impression, and once that hollow forms it changes the way the whole sleep surface supports your spine.

There is a hygiene dimension too. The average adult loses around half a litre of moisture and roughly a gram of skin each night, all of which feeds dust mites and, over time, can encourage mildew deep in the fillings. None of this is alarming, but it does explain why a mattress that is rotated, protected and cleaned regularly stays fresher, smells better and holds its shape far longer than one that is simply slept on and forgotten. A few minutes of maintenance every month genuinely pays for itself.

The good news is that mattress care is undemanding. There are no special products to buy and no complicated schedules to follow, just a handful of habits worth building into your routine. The sections below cover each one in turn, starting with the most important and most often neglected: rotation.

2. Rotating and flipping correctly

Rotating means turning the mattress 180 degrees so the end that was at your head is now at your feet. This spreads wear evenly across the surface and stops a permanent dip forming where you sleep. As a rule, rotate a new mattress once a month for the first three months while the fillings are settling, then every three to four months after that. Set a reminder on your phone or tie it to the start of each season so it never slips your mind.

Flipping is different and depends on the build. Many modern mattresses, including most pocket-sprung and memory-foam models, are single-sided: they have a dedicated comfort layer on top and a firmer support base underneath, so they should only ever be rotated, never flipped. Double-sided or traditional “turnable” mattresses can be flipped over completely as well as rotated, which distributes wear across two sleep surfaces. Check the care label or product description before you turn anything over.

If you have just bought a new mattress, the first few weeks are when consistent rotation matters most. Pairing it with the right base is equally important, which we cover in section four. For a refresher on choosing the correct size and feel in the first place, our mattress buying guide walks through tension, fillings and depth in detail.

3. Protecting it from day one

The cheapest and most effective thing you can do for any mattress is to fit a protector before you ever sleep on it. A good protector forms a barrier against perspiration, spills, skin cells and dust mites, all of which would otherwise work their way into the fillings where they cannot be cleaned out. It is far easier to wash a protector at 60 degrees than to rescue a stained mattress, and many manufacturers will only honour a guarantee if the mattress has been kept stain-free.

• Quilted protectors add a thin layer of padding and feel soft underhand, ideal for everyday protection against moisture and dust.
• Waterproof or terry-towelling protectors use a breathable membrane to block liquids completely, which is the sensible choice for children’s beds, guest rooms and anyone prone to night sweats.
• Mattress toppers sit on top to tune the feel firmer or softer, and a washable topper takes the brunt of daily wear so the mattress beneath stays pristine.

Beyond a protector, wash your bedding weekly at 60 degrees where the fabric allows, as this is the temperature that reliably kills dust mites and removes the oils that build up on sheets. Keeping pets off the bed, banning food and drink in the bedroom and using a fitted sheet over the protector all add further layers of defence. These small habits keep the sleep surface hygienic and dramatically reduce how often deep cleaning is needed. The same protect-first principle applies across the home, and our furniture care guide covers the rest of your bedroom pieces.

4. The right base and support

A mattress is only ever as good as what sits beneath it, and the wrong base will void guarantees and cause premature sagging no matter how well you care for the rest. The base provides ventilation and even support, so matching it to your mattress type is part of looking after it. Pairing a new mattress with an old, worn divan or sagging slats undoes much of your maintenance effort.

Whichever base you use, make sure slats are no more than around 7 centimetres apart; wider gaps let the mattress dip between them and can invalidate the warranty. Airflow matters too, as a mattress that cannot breathe traps moisture underneath and risks mildew. If you have a solid-top base or an ottoman, lift the mattress every month or two and leave it to air. Browse compatible frames in our beds collection, and if you are short on space the ottoman beds range adds generous storage without sacrificing support.

5. Your regular cleaning routine

Deep-cleaning a mattress takes around twenty minutes and only needs doing two to four times a year, ideally each time you rotate it. Start by stripping the bed and washing all the bedding and the protector on a hot wash. Then vacuum the entire surface using the upholstery attachment, working in overlapping strokes and paying attention to the seams and piping where dust and skin cells collect. This single step removes the bulk of allergens that feed dust mites.

1. Strip and wash all bedding and the protector at 60 degrees.
2. Vacuum thoroughly with the upholstery tool, including both sides if the mattress is turnable.
3. Spot-treat any marks while the surface is bare (see section six).
4. Deodorise by sieving bicarbonate of soda over the top, leaving it for several hours, then vacuuming it away.
5. Air it with the windows open before remaking the bed.

Between deep cleans, a quick weekly vacuum when you change the sheets keeps things in check, and airing the mattress for half an hour each morning before making the bed lets overnight moisture evaporate rather than soaking into the fillings. A bedroom kept cool and well ventilated does much of the hygiene work for you, so open a window daily where you can.

6. Tackling spills and stains

Speed is everything with spills. Blot, never rub, with a clean dry cloth or paper towel to lift as much liquid as possible before it spreads into the fillings. Rubbing only pushes the stain deeper and wider. Once you have blotted, treat the mark with the gentlest effective method, working from the outside of the stain inwards so you do not enlarge it. The golden rule is to use as little moisture as possible, because a mattress that gets soaked is very slow to dry and prone to mildew.

• General stains: mix a little washing-up liquid into cool water, dampen a cloth and dab gently, then blot with a clean damp cloth to lift the residue.
• Blood, urine and other protein stains: use cold water only, as heat sets these permanently. An enzyme-based cleaner or a paste of bicarbonate of soda works well; dab, leave, then blot away.
• Sweat and yellowing: a 50:50 solution of white vinegar and water, lightly applied and blotted, helps lift discolouration and neutralise odour.

Whatever you use, finish by blotting with a cloth dampened in clean water to remove any cleaning residue, then let the area dry completely before remaking the bed. A hairdryer on a cool setting or a fan speeds drying and helps prevent watermarks. Always test any solution on a hidden corner first, and check the care label, as some covers should not be treated with vinegar or enzyme cleaners.

7. Freshening and removing odours

Mattresses absorb odours gradually from perspiration and humidity, and the simplest fix is also the most effective. Sieve a generous, even layer of bicarbonate of soda across the whole surface, leave it to draw out moisture and smells for at least a few hours (overnight is better), then vacuum it off thoroughly. Bicarbonate of soda is a natural deodoriser and gently lifts trapped moisture at the same time, so this doubles as part of your deep-clean routine.

For a lightly scented finish, you can stir a few drops of lavender or another essential oil into the bicarbonate before sprinkling, which leaves a subtle, calming fragrance well suited to the bedroom. Avoid spraying perfumes or air fresheners directly onto the mattress, as these add moisture and simply mask odours rather than removing the cause. Good ventilation remains the best long-term defence: an aired, dry mattress rarely develops a smell in the first place.

A new mattress may have a faint manufacturing smell, sometimes called off-gassing, when first unwrapped. This is harmless and fades within a few days; simply stand the mattress in a well-ventilated room for several hours before use and the odour will dissipate. If a persistent musty smell ever returns despite airing and deodorising, it usually points to trapped moisture underneath, which is your cue to check the base ventilation covered in section four.

8. When to replace your mattress

Even a well-maintained mattress eventually reaches the end of its useful life, and recognising the signs saves you months of poor sleep. As a guide, most mattresses need replacing somewhere between seven and ten years, though heavier use, a poor base or simply a change in what your body needs can shorten that. The clearest test is how you feel: if you regularly wake stiff or unrested, or sleep better in a hotel bed, your mattress is likely past its best.

• Visible sagging, dips or lumps that no longer spring back after rotating.
• Springs you can feel or hear, or fillings that have clearly bunched.
• Waking with aches in your back, hips or shoulders that ease as the day goes on.
• Worsening allergies or congestion overnight despite regular cleaning.
• The mattress is more than seven to eight years old and no longer comfortable.

When the time comes, choosing the right replacement is its own task, and getting the size and tension right is half the battle. Our bed and mattress size guide sets out the exact dimensions for every UK size, while the full mattresses range covers everything from memory foam to pocket-sprung. If you are updating the frame at the same time, it is worth refreshing the wider bedroom setup so the new mattress sits on a base that will help it last.
