25 Things You Can (and Can't) Do With Your Mattress

Reading Time: 14 minutes

We hear "can I...?" questions about mattresses every single day at our Brantford showroom. Can I flip it? Can I put it on the floor? Can I clean it with vinegar? Can I bend it to get it up the stairs?

Some of the answers are obvious. Some are not. And some of the things people do with their mattresses make Brad visibly wince. After 38 years of selling, delivering, and fitting mattresses, we have seen it all. This is our definitive list of 25 things you can (and absolutely cannot) do with your mattress.

13 Things You CAN Do With Your Mattress

1. Rotate It Every 3 to 6 Months

Rotating your mattress 180 degrees (head to foot) is one of the simplest ways to extend its life. It distributes body weight more evenly across the sleeping surface and prevents premature compression in the spots where your hips and shoulders press hardest. Most manufacturers recommend rotating every three to six months, and it takes two people less than a minute.

2. Use a Mattress Protector (and You Really Should)

A waterproof mattress protector is the single best investment you can make after buying a mattress. It shields against sweat, spills, dead skin cells, and dust mite accumulation without changing the feel of your bed. A good protector costs $40 to $80 and can add years to your mattress's lifespan. We carry them in our Brantford showroom and can match one to your mattress.

3. Vacuum It Quarterly

Yes, you can vacuum your mattress, and you should. Use the upholstery attachment on your vacuum cleaner and run it across the entire surface every three months or so. This removes dust, dead skin cells, pet dander, and the dust mites that feed on all of it. If anyone in your household has allergies, vacuuming monthly is even better.

4. Put It on a Platform Bed (Without a Box Spring)

Modern mattresses, especially foam and hybrid models, do not require a box spring. A platform bed with solid slats (spaced no more than 3 inches apart) provides adequate support and airflow. Many people prefer the clean look of a platform over a traditional box spring setup, and there is nothing wrong with that.

5. Pair It With an Adjustable Base

Most modern mattresses are compatible with adjustable bases, which let you raise the head or foot of the bed. This is useful for sleep apnea (head elevation), acid reflux management, reading in bed, or simply finding your most comfortable angle. Check your mattress warranty to confirm compatibility, but most pocket coil, foam, and hybrid mattresses work fine.

6. Add a Mattress Topper

If your mattress is structurally sound but the comfort layer has softened, a quality topper can buy you another year or two. A 2-to-3-inch memory foam or latex topper adds a fresh comfort surface without replacing the entire mattress. Just know that a topper cannot fix a mattress with deep sagging or broken springs.

7. Spot Clean Stains With Mild Detergent

Accidents happen. When they do, blot (do not rub) the area with a cloth dampened with cold water and a small amount of mild dish soap or laundry detergent. Work from the outside of the stain inward. Then blot with a clean damp cloth to remove the soap, and let the area air dry completely before putting sheets back on. Our full stain removal guide covers every type of stain.

8. Let It Air Out

When you wash your sheets, leave the mattress bare for an hour or two before remaking the bed. This lets moisture evaporate and allows fresh air to circulate through the surface. It is an especially good habit during Ontario's humid summers, when trapped moisture can become a real problem.

9. Break It In for 30 Days Before Judging

A new mattress can feel strange for the first few weeks. Your body is adapting from the worn-out contours of your old mattress to a new support profile. Most manufacturers recommend 30 days of regular use before deciding whether the mattress is right for you. That stiff or "different" feeling usually resolves by week three or four.

10. Keep It Past 10 Years (If It Is Still Good)

The "replace every 7 to 10 years" guideline is exactly that: a guideline. If your mattress shows no visible sagging, still supports your body without pain, and has been well maintained with a protector and regular rotation, there is no reason to replace it at exactly the 10-year mark. Some well-made mattresses with quality materials can last 12 to 15 years. Judge by feel and condition, not by a calendar.

11. Donate It (If It Is in Decent Shape)

If your mattress is structurally sound with no stains, rips, or infestations, many charities will accept it. In the Brantford area, organizations like the Salvation Army and Habitat for Humanity ReStore accept gently used mattresses. Check their current policies first, as some have specific condition requirements.

12. Use It on Bed Slats (With Proper Spacing)

Slats work as mattress support as long as they are no more than 3 inches apart and made from solid wood that will not bow under weight. If the gaps are wider, you can add a bunkie board on top for a continuous support surface. Our foundation guide covers all the options.

13. Read the Law Tag (Yes, That One)

The white tag sewn into your mattress contains important information: materials used, manufacturing date, and warranty reference numbers. Contrary to the old joke, it is not illegal for you to remove the tag (the "do not remove" language is directed at retailers before the sale). But keeping it attached is wise because you will need it if you ever file a warranty claim.

12 Things You Should NOT Do With Your Mattress

14. Do Not Put It on the Floor Permanently

This is the number one question we get: "Can I just put my mattress on the floor?" Temporarily, yes. A week between bed frames is fine. But long-term floor placement traps moisture underneath the mattress, especially on concrete or in basements. That moisture creates the conditions for mould and mildew, which destroy the mattress from the bottom up. It also voids most warranties. Get a proper foundation.

15. Do Not Flip a One-Sided Mattress

Most modern mattresses are designed with comfort layers only on the top surface. The bottom is a support base, not a sleeping surface. Flipping a one-sided mattress means sleeping on the base, which is flat, hard, and not designed for your body. If you want a flippable mattress, look for one specifically designed that way, like our Sleep In Canadian-made flippable mattresses or the Restonic Revive Reflections ET.

16. Do Not Fold or Bend It (Unless It Is All-Foam)

Pocket coil and hybrid mattresses contain internal structures (border wires, coil systems, reinforced edges) that are not meant to bend. Folding or bending a coil mattress can permanently deform the coil unit and void your warranty. All-foam mattresses are more flexible, which is why "bed in a box" companies can compress and ship them, but even foam mattresses should not be folded in half and stored that way.

17. Do Not Jump on It

We know this sounds like something your mother would say, but it is legitimate advice. Jumping concentrates your body weight into a small impact area, which can damage coil systems, delaminate foam layers, and warp edge support structures. Children are especially notorious for this. If durability matters to you, keep the trampolining to the backyard.

18. Do Not Use Bleach or Harsh Chemicals

Bleach, hydrogen peroxide (at high concentrations), and ammonia-based cleaners can break down foam cell structures, discolour fabric, and leave chemical residues that off-gas into your sleeping environment. For stain removal, stick with mild detergent and cold water. Enzyme-based cleaners designed for mattresses are also safe for most types.

19. Do Not Ignore Sagging Over 1.5 Inches

A slight body impression is normal, especially in the first year. But visible sagging deeper than 1.5 inches (about the width of two stacked coins) means the support system is failing. Sleeping in a sag puts your spine out of alignment and can cause or worsen upper back pain, hip pain, and poor sleep quality. If your mattress is sagging this much, it is time to replace it.

20. Do Not Steam Clean Without Checking First

Steam cleaning can kill dust mites and sanitise surfaces, which sounds great. But the moisture from steam can be damaging to memory foam and some hybrid mattress constructions. Some warranties explicitly prohibit steam cleaning. Always check your manufacturer's care instructions before introducing steam to your mattress. For most people, vacuuming and spot cleaning are safer alternatives.

21. Do Not Lift It by the Side Handles

Those handles on the side of your mattress are for repositioning, not lifting. They are designed to help you shift the mattress on your bed frame, not to bear the full weight of a 60-to-100-pound mattress. Lifting by the handles can tear the fabric and damage the mattress casing. When moving your mattress, grab it from the bottom and carry it flat with a partner.

22. Do Not Eat and Drink in Bed Regularly

The occasional cup of tea in bed is fine. Making it a daily habit is asking for trouble. Crumbs attract insects, liquid spills soak through sheets and into foam, and food residue creates odours that are difficult to remove. If you enjoy eating in bed, at the very least use a mattress protector and a proper tray. Your mattress will thank you.

23. Do Not Skip the Foundation and Expect Your Warranty to Hold

Almost every mattress warranty requires the use of a proper support foundation: a box spring, platform bed, slatted frame (with slats no more than 3 inches apart), or adjustable base. If you file a warranty claim and your mattress was sitting on the floor, on an old frame with broken slats, or on an inappropriate surface, the manufacturer will deny the claim. It is one of the most common reasons warranty claims get rejected.

24. Do Not Store It Without Protection

If you need to store a mattress, wrap it in a breathable mattress bag (not plastic, which traps moisture). Store it flat in a dry, temperature-controlled space. Do not lean it against a wall for months, as this can cause the internal materials to shift and compress unevenly. Garages and unheated sheds in Ontario are poor storage options because of humidity swings and temperature extremes.

25. Do Not Assume a Mattress Topper Fixes Everything

A topper can add comfort to a mattress that has lost its surface softness. It cannot fix structural problems. If your mattress is sagging, has broken coils, or has lost its core support, a topper is a bandage on a deeper problem. You would not put a new coat of paint on a house with a crumbling foundation. The same logic applies here. If the support system is gone, the mattress needs to be replaced, not topped.

When It Is Time to Replace Instead of Maintain

All the care and maintenance in the world cannot make a mattress last forever. Here are the signs that your mattress has reached the end of its useful life:

If you recognise two or more of these signs, it is probably time. The average Canadian spends roughly one-third of their life in bed, and sleeping on a failing mattress affects everything from chronic pain to energy levels to mood. Jacobson et al. (2008) found in the Journal of Chiropractic Medicine that switching to a new, properly supportive mattress significantly reduced both back pain and shoulder pain in study participants.
