Tip #5: Store It If You Don’t Need It All the Time

Tip #1: Let It Breathe

Why it matters: When you first unbox your mattress topper, don’t be alarmed by a slight “new foam” smell. It’s completely normal—it just needs time to off-gas.

What to do:
Unroll it in a well-ventilated area and allow 48 hours for it to fully expand and air out. This not only dissipates any odor but also ensures the foam settles into its intended shape before use.

Tip #2: Washing the Cover

Why it matters: A clean cover helps keep allergens, dust, and sweat from sinking into the foam. But improper washing can shrink or wear it out.

What to do:
Unzip the cover and wash it separately using a cold, gentle cycle. Avoid harsh detergents and skip the bleach—less is more when it comes to preserving fabric integrity.

Trick: Brightening Dull Spots

Why it matters: Over time, even with a cover, your topper may develop yellowish spots or lose its brightness—especially in humid conditions.

What to do:
Mix 2 parts 3% hydrogen peroxide with 1 part water. Spray lightly on affected areas, let it sit, and air dry. It’s a chemical-free refresh that brings back the brightness without damaging the foam.

Tip #3: Drying the Cover

Why it matters: Heat can damage elastic fibers and cause shrinkage. Drying smart preserves fit and softness.

What to do:

• Option A: Hang dry for maximum fabric longevity.
• Option B: If using a dryer, choose the lowest heat and longest time setting to ensure an even, gentle dry.

Tip #4: Spot Clean the Foam

Why it matters: Foam absorbs moisture easily, and full submersion will ruin it.

What to do:
Dab (don’t soak) spots with warm water and a tiny amount of dish soap. Use a clean cloth to blot the area gently, then air dry thoroughly before re-covering.

Tip #5: Store It Away Properly

Why it matters: Not using your topper for a while? Storing it properly keeps it fresh and ready for next time.

What to do:
Roll (don’t fold) your topper and store it in a cool, dry place—preferably in a breathable storage bag. Avoid humid closets or hot attics. For visual learners, we’ve made a quick how-to video you can watch here.
