TL;DR
- Yes, Puffy mattress covers are machine washable on a gentle cycle with cold water (Puffy, 2024).
- Avoid bleach, fabric softener, and high heat – they break down the fabric and any waterproof lining (Puffy, 2024).
- Wash the cover alone or with lightweight items like sheets; heavier items like towels can stretch or tear it (Puffy, 2024).
- Air dry when possible, or use a dryer’s low heat setting only (Puffy, 2024).
- Always check the care label first, since some covers use different materials with different limits (Persil, 2024).
Can You Machine Wash a Puffy Mattress Cover?
Yes. Puffy mattress covers are designed to be machine washed, but only on the right settings. <cite index=”5-1″>A gentle cycle with cold water protects the fabric, since hot water can cause shrinking</cite>.
Skipping the correct settings is the main reason covers wear out early. A front-loading machine is gentler than a top-loader with a center agitator, which can tear the material over repeated washes (Persil, 2024).
Check the care label before your first wash. Puffy’s covers come in a few materials – cotton blends, bamboo, and waterproof laminate – and each has slightly different limits (Persil, 2024).
What You Need Before You Start
- A washing machine with a gentle or delicate cycle
- Mild, liquid laundry detergent (no bleach)
- Cold or lukewarm water setting
- A dryer with a low heat option, or a flat space to air dry
Step 1: Check the Care Label
Look at the tag sewn into the cover for material-specific instructions. Puffy’s standard covers are machine washable, but waterproof models need extra care to protect the laminate layer underneath (Puffy, 2024).
If the label lists a specific water temperature or forbids machine washing, follow that over any general guide – including this one.
Step 2: Pre-Treat Any Stains
Work a small amount of liquid detergent directly into visible stains and let it sit for 5 to 10 minutes before washing (Persil, 2024). This loosens the stain so the wash cycle can finish the job instead of setting it further.
Skip this step if the cover has no visible stains – pre-treating a clean cover adds unnecessary detergent residue.
Step 3: Load the Machine Correctly
Wash the cover by itself, or pair it with light items such as sheets or pillowcases. <cite index=”5-1″>Washing with heavier items like towels can cause the fabric to stretch or tear from the added friction</cite>.
Distribute the cover evenly in the drum so the spin cycle doesn’t throw it off balance (Puffy, 2024).
Step 4: Select Gentle Cycle, Cold Water
Set the machine to a gentle or delicate cycle with cold water. <cite index=”5-1″>Hot water can shrink the fabric, while cold water preserves both size and softness</cite>. Use a mild detergent and skip bleach or harsh chemicals, which can weaken the material (Puffy, 2024).
Step 5: Dry on Low Heat or Air Dry
After washing, avoid high heat in the dryer – it can shrink or damage the fabric (Puffy, 2024). Air drying is the safer default, especially for waterproof covers, since heat can break down the protective coating over time (Puffy, 2024).
If you use a dryer, choose a low heat setting and remove the cover promptly once it’s dry to prevent over-drying and stiffness.
Common Problems and How to Fix Them
| Problem | Likely Cause | Solution |
|---|---|---|
| Cover shrank after washing | Hot water or high heat drying | Rewash on cold, air dry going forward; shrinkage is often permanent |
| Fabric feels stiff | Detergent residue not fully rinsed | Run an extra rinse cycle next time |
| Waterproof layer peeling | Bleach, fabric softener, or high heat | Stop using these products; peeling laminate cannot be reversed |
| Cover came out twisted or torn | Washed with heavy items like towels | Wash the cover alone or with lightweight items only |
Frequently Asked Questions About Washing a Puffy Mattress Cover

Yes. Puffy mattress covers are machine washable on a gentle cycle with cold water and a mild detergent (Puffy, 2024). Always check the care label first, since waterproof models need extra care.
What water temperature should you use?
